Refactor ESLint config (#13482) We would like to insert TypeScript into the ESLint configuration, and because of the way that the current config is organized, that is not easy to do. Most files are assumed to be files that are suited for running in a browser context. This isn't correct, as we should expect most files to work in a Node context instead. This is because all browser-based files will be run through a transpiler that is able to make use of Node-specific variables anyway. There are a couple of important ways we can categories files which our ESLint config should be capable of handling well: * Is the file a script or a module? In other words, does the file run procedurally or is the file intended to be brought into an existing file? * If the file is a module, does it use the CommonJS syntax (`require()`) or does it use the ES syntax (`import`/`export`)? When we introduce TypeScript, this set of questions will become: * Is the file a script or a module? * If the file is a module, is it a JavaScript module or a TypeScript module? * If the file is a JavaScript module, does it use the CommonJS syntax (`require()`) or does it use the ES syntax (`import`/`export`)? To represent these divisions, this commit removes global rules — so now all of the rules are kept in `overrides` for explicitness — and sets up rules for CommonJS- and ES-module-compatible files that intentionally do not overlap with each other. This way TypeScript (which has its own set of rules independent from JavaScript and therefore shouldn't overlap with the other rules either) can be easily added later. Finally, this commit splits up the ESLint config into separate files and adds documentation to each section. This way sets of rules which are connected to a particular plugin (`jsdoc`, `@babel`, etc.) can be easily understood instead of being obscured.

Exclude files from builds by build type (#12521) This PR enables the exclusion of JavaScript and JSON source by `buildType`, and enables the running of `eslint` under LavaMoat. 80-90% of the changes in this PR are `.patch` files and LavaMoat policy additions. The file exclusion is designed to work in conjunction with our code fencing. If you forget to fence an import statement of an excluded file, the application will now error on boot. **This PR commits us to a particular naming convention for files intended only for certain builds.** Continue reading for details. ### Code Fencing and ESLint When a file is modified by the code fencing transform, we run ESLint on it to ensure that we fail early for syntax-related issues. This PR adds the first code fences that will be actually be removed in production builds. As a consequence, this was also the first time we attempted to run ESLint under LavaMoat. Making that work required a lot of manual labor because of ESLint's use of dynamic imports, but the manual changes necessary were ultimately quite minor. ### File Exclusion For all builds, any file in `app/`, `shared/` or `ui/` in a sub-directory matching `**/${otherBuildType}/**` (where `otherBuildType` is any build type except `main`) will be added to the list of excluded files, regardless of its file extension. For example, if we want to add one or more pages to the UI settings in Flask, we'd create the folder `ui/pages/settings/flask`, add any necessary files or sub-folders there, and fence the import statements for anything in that folder. If we wanted the same thing for Beta, we would name the directory `ui/pages/settings/beta`. As it happens, we already organize some of our source files in this way, namely the logo JSON for Beta and Flask builds. See `ui/helpers/utils/build-types.js` to see how this works in practice. Because the list of ignored filed is only passed to `browserify.exclude()`, any files not bundled by `browserify` will be ignored. For our purposes, this is mostly relevant for `.scss`. Since we don't have anything like code fencing for SCSS, we'll have to consider how to handle our styles separately.

Add TypeScript migration dashboard (#13820) As we convert parts of the codebase to TypeScript, we will want a way to track progress. This commit adds a dashboard which displays all of the files that we wish to convert to TypeScript and which files we've already converted. The list of all possible files to convert is predetermined by walking the dependency graph of each entrypoint the build system uses to compile the extension (the files that the entrypoint imports, the files that the imports import, etc). The list should not need to be regenerated, but you can do it by running: yarn ts-migration:enumerate The dashboard is implemented as a separate React app. The CircleCI configuration has been updated so that when a new commit is pushed, the React app is built and stored in the CircleCI artifacts. When a PR is merged, the built files will be pushed to a separate repo whose sole purpose is to serve the dashboard via GitHub Pages (this is the same way that the Storybook works). All of the app code and script to build the app are self-contained under `development/ts-migration-dashboard`. To build this app yourself, you can run: yarn ts-migration:dashboard:build or if you want to build automatically as you change files, run: yarn ts-migration:dashboard:watch Then open the following file in your browser (there is no server component): development/ts-migration-dashboard/build/index.html Finally, although you shouldn't have to do this, to manually deploy the dashboard once built, you can run: git remote add ts-migration-dashboard git@github.com:MetaMask/metamask-extension-ts-migration-dashboard.git yarn ts-migration:dashboard:deploy

Update ESLint config to v8 (#12886) The ESLint config has been updated to v8. The breaking changes are: * The Prettier rule `quoteProps` has been changed from `consistent` to `as-needed`, meaning that if one key requires quoting, only that key is quoted rather than all keys. * The ESLint rule `no-shadow` has been made more strict. It now prevents globals from being shadowed as well. Most of these changes were applied with `yarn lint:fix`. Only the shadowing changes required manual fixing (shadowing variable names were either replaced with destructuring or renamed). The dependency `globalThis` was added to the list of dynamic dependencies in the build system, where it should have been already. This was causing `depcheck` to fail because the new lint rules required removing the one place where `globalThis` had been erroneously imported previously. A rule requiring a newline between multiline blocks and expressions has been disabled temporarily to make this PR smaller and to avoid introducing conflicts with other PRs.

The breaking changes are: * The Prettier rule `quoteProps` has been changed from `consistent` to `as-needed`, meaning that if one key requires quoting, only that key is quoted rather than all keys. * The ESLint rule `no-shadow` has been made more strict. It now prevents globals from being shadowed as well. Most of these changes were applied with `yarn lint:fix`. Only the shadowing changes required manual fixing (shadowing variable names were either replaced with destructuring or renamed). The dependency `globalThis` was added to the list of dynamic dependencies in the build system, where it should have been already. This was causing `depcheck` to fail because the new lint rules required removing the one place where `globalThis` had been erroneously imported previously. A rule requiring a newline between multiline blocks and expressions has been disabled temporarily to make this PR smaller and to avoid introducing conflicts with other PRs.

Refactor ESLint config (#13482) We would like to insert TypeScript into the ESLint configuration, and because of the way that the current config is organized, that is not easy to do. Most files are assumed to be files that are suited for running in a browser context. This isn't correct, as we should expect most files to work in a Node context instead. This is because all browser-based files will be run through a transpiler that is able to make use of Node-specific variables anyway. There are a couple of important ways we can categories files which our ESLint config should be capable of handling well: * Is the file a script or a module? In other words, does the file run procedurally or is the file intended to be brought into an existing file? * If the file is a module, does it use the CommonJS syntax (`require()`) or does it use the ES syntax (`import`/`export`)? When we introduce TypeScript, this set of questions will become: * Is the file a script or a module? * If the file is a module, is it a JavaScript module or a TypeScript module? * If the file is a JavaScript module, does it use the CommonJS syntax (`require()`) or does it use the ES syntax (`import`/`export`)? To represent these divisions, this commit removes global rules — so now all of the rules are kept in `overrides` for explicitness — and sets up rules for CommonJS- and ES-module-compatible files that intentionally do not overlap with each other. This way TypeScript (which has its own set of rules independent from JavaScript and therefore shouldn't overlap with the other rules either) can be easily added later. Finally, this commit splits up the ESLint config into separate files and adds documentation to each section. This way sets of rules which are connected to a particular plugin (`jsdoc`, `@babel`, etc.) can be easily understood instead of being obscured.

Permission System 2.0 (#12243) # Permission System 2.0 ## Background This PR migrates the extension permission system to [the new `PermissionController`](https://github.com/MetaMask/snaps-skunkworks/tree/main/packages/controllers/src/permissions). The original permission system, based on [`rpc-cap`](https://github.com/MetaMask/rpc-cap), introduced [`ZCAP-LD`](https://w3c-ccg.github.io/zcap-ld/)-like permissions to our JSON-RPC stack. We used it to [implement](https://github.com/MetaMask/metamask-extension/pull/7004) what we called "LoginPerSite" in [version 7.7.0](https://github.com/MetaMask/metamask-extension/releases/tag/v7.7.0) of the extension, which enabled the user to choose which accounts, if any, should be exposed to each dapp. While that was a worthwhile feature in and of itself, we wanted a permission _system_ in order to enable everything we are going to with Snaps. Unfortunately, the original permission system was difficult to use, and necessitated the creation of the original `PermissionsController` (note the "s"), which was more or less a wrapper for `rpc-cap`. With this PR, we shake off the yoke of the original permission system, in favor of the modular, self-contained, ergonomic, and more mature permission system 2.0. Note that [the `PermissionController` readme](https://github.com/MetaMask/snaps-skunkworks/tree/main/packages/controllers/src/permissions/README.md) explains how the new permission system works. The `PermissionController` and `SubjectMetadataController` are currently shipped via `@metamask/snap-controllers`. This is a temporary state of affairs, and we'll move them to `@metamask/controllers` once they've landed in prod. ## Changes in Detail First, the changes in this PR are not as big as they seem. Roughly half of the additions in this PR are fixtures in the test for the new migration (number 68), and a significant portion of the remaining ~2500 lines are due to find-and-replace changes in other test fixtures and UI files. - The extension `PermissionsController` has been deleted, and completely replaced with the new `PermissionController` from [`@metamask/snap-controllers`](https://www.npmjs.com/package/@metamask/snap-controllers). - The original `PermissionsController` "domain metadata" functionality is now managed by the new `SubjectMetadataController`, also from [`@metamask/snap-controllers`](https://www.npmjs.com/package/@metamask/snap-controllers). - The permission activity and history log controller has been renamed `PermissionLogController` and has its own top-level state key, but is otherwise functionally equivalent to the existing implementation. - Migration number 68 has been added to account for the new state changes. - The tests in `app/scripts/controllers/permissions` have been migrated from `mocha` to `jest`. Reviewers should focus their attention on the following files: - `app/scripts/` - `metamask-controller.js` - This is where most of the integration work for the new `PermissionController` occurs. Some functions that were internal to the original controller were moved here. - `controllers/permissions/` - `selectors.js` - These selectors are for `ControllerMessenger` selector subscriptions. The actual subscriptions occur in `metamask-controller.js`. See the `ControllerMessenger` implementation for details. - `specifications.js` - The caveat and permission specifications are required by the new `PermissionController`, and are used to specify the `eth_accounts` permission and its JSON-RPC method implementation. See the `PermissionController` readme for details. - `migrations/068.js` - The new state should be cross-referenced with the controllers that manage it. The accompanying tests should also be thoroughly reviewed. Some files may appear new but have just moved and/or been renamed: - `app/scripts/lib/rpc-method-middleware/handlers/request-accounts.js` - This was previously implemented in `controllers/permissions/permissionsMethodMiddleware.js`. - `test/mocks/permissions.js` - A truncated version of `test/mocks/permission-controller.js`.

Normalize extension verison to SemVer (#12254) The extension version used throughout the wallet is now normalized to a SemVer-compliant version that matches the version used in `package.json`. We use this version for display on the "About" page, and we attach it to all error reports and metric events, so it's important that we format it consistently so that we can correlate events on the same version across different browsers. This normalization step is necessary because Firefox and Chrome both have different requirements for the extension version, and neither is SemVer-compliant.

Add build-time code exclusion using code fencing (#12060) This PR adds build-time code exclusion by means of code fencing. For details, please see the README in `./development/build/transforms`. Note that linting of transformed files as a form of validation is added in a follow-up, #12075. Hopefully exhaustive tests are added to ensure that the transform works according to its specification. Since these tests are Node-only, they required their own Jest config. The recommended way to work with multiple Jest configs is using the `projects` field in the Jest config, however [that feature breaks coverage collection](https://github.com/facebook/jest/issues/9628). That being the case, I had to set up two separate Jest configs. In order to get both test suites to run in parallel, Jest is now invoked via a script, `./test/run-jest.sh`. By way of example, this build system feature allows us to add fences like this: ```javascript this.store.updateStructure({ ..., GasFeeController: this.gasFeeController, TokenListController: this.tokenListController, ///: BEGIN:ONLY_INCLUDE_IN(beta) PluginController: this.pluginController, ///: END:ONLY_INCLUDE_IN }); ``` Which at build time are transformed to the following if the build type is not `beta`: ```javascript this.store.updateStructure({ ..., GasFeeController: this.gasFeeController, TokenListController: this.tokenListController, }); ``` Co-authored-by: Mark Stacey <markjstacey@gmail.com>

There are a couple of important ways we can categories files which our ESLint config should be capable of handling well: * Is the file a script or a module?

When we introduce TypeScript, this set of questions will become: * Is the file a script or a module? * If the file is a module, is it a JavaScript module or a TypeScript module? * If the file is a JavaScript module, does it use the CommonJS syntax (`require()`) or does it use the ES syntax (`import`/`export`)? To represent these divisions, this commit removes global rules — so now all of the rules are kept in `overrides` for explicitness — and sets up rules for CommonJS- and ES-module-compatible files that intentionally do not overlap with each other. This way TypeScript (which has its own set of rules independent from JavaScript and therefore shouldn't overlap with the other rules either) can be easily added later. Finally, this commit splits up the ESLint config into separate files and adds documentation to each section.

Permission System 2.0 (#12243) # Permission System 2.0 ## Background This PR migrates the extension permission system to [the new `PermissionController`](https://github.com/MetaMask/snaps-skunkworks/tree/main/packages/controllers/src/permissions). The original permission system, based on [`rpc-cap`](https://github.com/MetaMask/rpc-cap), introduced [`ZCAP-LD`](https://w3c-ccg.github.io/zcap-ld/)-like permissions to our JSON-RPC stack. We used it to [implement](https://github.com/MetaMask/metamask-extension/pull/7004) what we called "LoginPerSite" in [version 7.7.0](https://github.com/MetaMask/metamask-extension/releases/tag/v7.7.0) of the extension, which enabled the user to choose which accounts, if any, should be exposed to each dapp. While that was a worthwhile feature in and of itself, we wanted a permission _system_ in order to enable everything we are going to with Snaps. Unfortunately, the original permission system was difficult to use, and necessitated the creation of the original `PermissionsController` (note the "s"), which was more or less a wrapper for `rpc-cap`. With this PR, we shake off the yoke of the original permission system, in favor of the modular, self-contained, ergonomic, and more mature permission system 2.0. Note that [the `PermissionController` readme](https://github.com/MetaMask/snaps-skunkworks/tree/main/packages/controllers/src/permissions/README.md) explains how the new permission system works. The `PermissionController` and `SubjectMetadataController` are currently shipped via `@metamask/snap-controllers`. This is a temporary state of affairs, and we'll move them to `@metamask/controllers` once they've landed in prod. ## Changes in Detail First, the changes in this PR are not as big as they seem. Roughly half of the additions in this PR are fixtures in the test for the new migration (number 68), and a significant portion of the remaining ~2500 lines are due to find-and-replace changes in other test fixtures and UI files. - The extension `PermissionsController` has been deleted, and completely replaced with the new `PermissionController` from [`@metamask/snap-controllers`](https://www.npmjs.com/package/@metamask/snap-controllers). - The original `PermissionsController` "domain metadata" functionality is now managed by the new `SubjectMetadataController`, also from [`@metamask/snap-controllers`](https://www.npmjs.com/package/@metamask/snap-controllers). - The permission activity and history log controller has been renamed `PermissionLogController` and has its own top-level state key, but is otherwise functionally equivalent to the existing implementation. - Migration number 68 has been added to account for the new state changes. - The tests in `app/scripts/controllers/permissions` have been migrated from `mocha` to `jest`. Reviewers should focus their attention on the following files: - `app/scripts/` - `metamask-controller.js` - This is where most of the integration work for the new `PermissionController` occurs. Some functions that were internal to the original controller were moved here. - `controllers/permissions/` - `selectors.js` - These selectors are for `ControllerMessenger` selector subscriptions. The actual subscriptions occur in `metamask-controller.js`. See the `ControllerMessenger` implementation for details. - `specifications.js` - The caveat and permission specifications are required by the new `PermissionController`, and are used to specify the `eth_accounts` permission and its JSON-RPC method implementation. See the `PermissionController` readme for details. - `migrations/068.js` - The new state should be cross-referenced with the controllers that manage it. The accompanying tests should also be thoroughly reviewed. Some files may appear new but have just moved and/or been renamed: - `app/scripts/lib/rpc-method-middleware/handlers/request-accounts.js` - This was previously implemented in `controllers/permissions/permissionsMethodMiddleware.js`. - `test/mocks/permissions.js` - A truncated version of `test/mocks/permission-controller.js`.

Normalize extension verison to SemVer (#12254) The extension version used throughout the wallet is now normalized to a SemVer-compliant version that matches the version used in `package.json`. We use this version for display on the "About" page, and we attach it to all error reports and metric events, so it's important that we format it consistently so that we can correlate events on the same version across different browsers. This normalization step is necessary because Firefox and Chrome both have different requirements for the extension version, and neither is SemVer-compliant.

Add build-time code exclusion using code fencing (#12060) This PR adds build-time code exclusion by means of code fencing. For details, please see the README in `./development/build/transforms`. Note that linting of transformed files as a form of validation is added in a follow-up, #12075. Hopefully exhaustive tests are added to ensure that the transform works according to its specification. Since these tests are Node-only, they required their own Jest config. The recommended way to work with multiple Jest configs is using the `projects` field in the Jest config, however [that feature breaks coverage collection](https://github.com/facebook/jest/issues/9628). That being the case, I had to set up two separate Jest configs. In order to get both test suites to run in parallel, Jest is now invoked via a script, `./test/run-jest.sh`. By way of example, this build system feature allows us to add fences like this: ```javascript this.store.updateStructure({ ..., GasFeeController: this.gasFeeController, TokenListController: this.tokenListController, ///: BEGIN:ONLY_INCLUDE_IN(beta) PluginController: this.pluginController, ///: END:ONLY_INCLUDE_IN }); ``` Which at build time are transformed to the following if the build type is not `beta`: ```javascript this.store.updateStructure({ ..., GasFeeController: this.gasFeeController, TokenListController: this.tokenListController, }); ``` Co-authored-by: Mark Stacey <markjstacey@gmail.com>

Make all named intrinsics non-modifiable (#11953) This PR makes ~all named intrinsics in all of our JavaScript processes non-modifiable. A named intrinsic is any property specified by the ECMAScript specification that exists on `globalThis` when the JavaScript process starts. We say that a property is non-modifiable if it is non-configurable and non-writable. We make exceptions for properties that meet any of the following criteria: 1. Properties that are non-configurable by the time `lockdown-run.js` is executed are not modified, because they can't be. 2. Properties that have accessor properties (`get` or `set`) are made non-configurable, but their writability cannot be modified, and is therefore left unchanged. It's unclear how many of the named intrinsics this applies to, if any, but it's good defensive programming, regardless.

Finally, this commit splits up the ESLint config into separate files and adds documentation to each section. This way sets of rules which are connected to a particular plugin (`jsdoc`, `@babel`, etc.) can be easily understood instead of being obscured.

Refactor ESLint config (#13482) We would like to insert TypeScript into the ESLint configuration, and because of the way that the current config is organized, that is not easy to do. Most files are assumed to be files that are suited for running in a browser context. This isn't correct, as we should expect most files to work in a Node context instead. This is because all browser-based files will be run through a transpiler that is able to make use of Node-specific variables anyway. There are a couple of important ways we can categories files which our ESLint config should be capable of handling well: * Is the file a script or a module? In other words, does the file run procedurally or is the file intended to be brought into an existing file? * If the file is a module, does it use the CommonJS syntax (`require()`) or does it use the ES syntax (`import`/`export`)? When we introduce TypeScript, this set of questions will become: * Is the file a script or a module? * If the file is a module, is it a JavaScript module or a TypeScript module? * If the file is a JavaScript module, does it use the CommonJS syntax (`require()`) or does it use the ES syntax (`import`/`export`)? To represent these divisions, this commit removes global rules — so now all of the rules are kept in `overrides` for explicitness — and sets up rules for CommonJS- and ES-module-compatible files that intentionally do not overlap with each other. This way TypeScript (which has its own set of rules independent from JavaScript and therefore shouldn't overlap with the other rules either) can be easily added later.
