Validation has been added to the build script when the "prod" target is
selected. We now ensure that all expected environment variables are
set, and that no extra environment variables are present (which might
indicate that the wrong configuration file is being used).
The `prod` target uses a new `.metamaskprodrc` configuration file. Each
required variable can be specified either via environment variable or
via this config file. CI will continue set these via environment
variable, but for local manual builds we can use the config file to
simplify the build process and ensure consistency.
A new "dist" target has been added to preserve the ability to build a
"production-like" build without this validation.
The config validation is invoked early in the script, in the CLI
argument parsing step, so that it would fail more quickly. Otherwise
we'd have to wait a few minutes longer for the validation to run.
This required some refactoring, moving functions to the utility module
and moving the config to a dedicated module.
Additionally, support has been added for all environment variables to
be set via the config file. Previously the values `PUBNUB_PUB_KEY`,
`PUBNUB_SUB_KEY`, `SENTRY_DSN`, and `SWAPS_USE_DEV_APIS` could only be
set via environment variable. Now, all of these variables can be set
either way.
Closes#15003
The build script now uses `yargs` rather than `minimist`. The CLI is
now better documented, and we have additional validation for each
option.
A patch for `yargs` was required because it would blow up on the line
`Error.captureStackTrace`. For some reason when running under LavaMoat,
that property did not exist.
Closes#12766
Adds a new flag, `--apply-lavamoat`, to the main build script. The flag controls whether LavaMoat is actually applied to the output of the build process. The flag defaults to `true`, but we explicitly set it to `false` in the `start` package script. Meanwhile, the `start:lavamoat` script is modified such that it applies LavaMoat to the build output in development mode, but it no longer runs the build process itself under LavaMoat as there aren't very compelling reasons to do so.
This change is motivated by the fact that development builds do not have their own dedicated LavaMoat policies, which causes development builds to fail since #14537. The downside of this change is that LavaMoat-related failures will not be detected when running `yarn start`. @kumavis has plans for fixing this problem in a future major version of the `@lavamoat` suite.
This commit modifies the build system so that TypeScript files can be
transpiled into ES5 just like JavaScript files.
Note that this commit does NOT change the build system to run TypeScript
files through the TypeScript compiler. In other words, no files will be
type-checked at the build stage, as we expect type-checking to be
handled elsewhere (live, via your editor integration with `tsserver`,
and before a PR is merged, via `yarn lint`). Rather, we merely instruct
Babel to strip TypeScript-specific syntax from any files that have it,
as if those files had been written using JavaScript syntax alone.
Why take this approach? Because it prevents the build process from being
negatively impacted with respect to performance (as TypeScript takes a
significant amount of time to run).
It's worth noting the downside of this approach: because we aren't
running files through TypeScript, but relying on Babel's [TypeScript
transform][1] to identify TypeScript syntax, this transform has to keep
up with any syntax changes that TypeScript adds in the future. In fact
there are a few syntactical forms that Babel already does not recognize.
These forms are rare or are deprecated by TypeScript, so I don't
consider them to be a blocker, but it's worth noting just in case it
comes up later. Also, any settings we place in `tsconfig.json` will be
completely ignored by Babel. Again, this isn't a blocker because there
are some analogs for the most important settings reflected in the
options we can pass to the transform. These and other caveats are
detailed in the [documentation for the transform][2].

This commit allows developers to write TypeScript files and lint them
(either via a language server in their editor of choice or through the
`yarn lint` command).
The new TypeScript configuration as well as the updated ESLint
configuration not only includes support for parsing TypeScript files,
but also provides some compatibility between JavaScript and TypeScript.
That is, it makes it possible for a TypeScript file that imports a
JavaScript file or a JavaScript file that imports a TypeScript file to
be linted.
Note that this commit does not integrate TypeScript into the build
system yet, so we cannot start converting files to TypeScript and
pushing them to the repo until that final step is complete.
The version of a build is now derived from both the `version` field in
`package.json` and the requested build type and version. The build type
and version are added onto the manifest version as a suffix, according
to the SemVer prerelease format.
We already have support in the extension for versions of this format,
but to apply a Flask or Beta version required manual updates to
`package.json`. Now it can be done just with build arguments.
A `get-version` module was created to make it easier to generate the
version in the various places we do that during the build. It was
created in the `development/lib` directory because it will be used by
other non-build development scripts in a future PR.
The `BuildType` constant was extracted to its own module as well, and
moved to the `development/lib` directory. This was to make it clear
that it's used by various different development scripts, not just the
build.
ESLint rules have been added to enforce our JSDoc conventions. These
rules were introduced by updating `@metamask/eslint-config` to v9.
Some of the rules have been disabled because the effort to fix all lint
errors was too high. It might be easiest to enable these rules one
directory at a time, or one rule at a time.
Most of the changes in this PR were a result of running
`yarn lint:fix`. There were a handful of manual changes that seemed
obvious and simple to make. Anything beyond that and the rule was left
disabled.
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 LavaMoat policy generation script would sporadically fail because
it ran the build concurrently three times, and the build includes
steps that delete the `dist` directory and write to it. So if one build
process tried to write to the directory after another deleted it, it
would fail.
This was solved by adding a new `--policy-only` flag to the build
script, and a new `scripts:prod` task. The `scripts:prod` task only
runs the script tasks for prod, rather than the entire build process.
The `--policy-only` flag stops the script tasks once the policy has
been written, and stops any other files from being written to disk.
This prevents the three concurrent build processes from getting in each
others way, and it dramatically speeds up the process.
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.
The build type (i.e. the distribution) is now included in the Sentry
environment during setup, for all builds except the "main" build. This
will allow us to track Flask and beta errors separately from other
errors.
A constant was created for the build types. The equivalent constant in
our build scripts was updated to match it more closely, for
consistency. We can't use the same constant in both places because our
shared constants are in modules that use ES6 exports, and our build
script does not yet support ES6 exports.
The singular `BuildType` was used rather than `BuildTypes` to match our
naming conventions elsewhere for enums. We name them like classes or
types, rather than like a collection.
Relates to #11896
The main `version` field in `package.json` will now include the beta
version (if present) rather than it being passed in via the CLI when
building. The `version` field is now a fully SemVer-compatible version,
with the added restriction that any prerelease portion of the version
must match the format `<build type>.<build version>`.
This brings the build in-line with the future release process we will
be using for the beta version. The plan is for each future release to
enter a "beta phase" where the version would get updated to reflect
that it's a beta, and we would increment this beta version over time as
we update the beta. The manifest gives us a place to store this beta
version. It was also important to replace the automatic minor bump
logic that was being used previously, because the version in beta might
not be a minor bump.
Additionally, the filename logic used for beta builds was updated to
be generic across all build types rather than beta-specific. This will
be useful for Flask builds in the future.
This is a refactor to replace the `isBeta` boolean with `buildType`
throughout the build system. This will allow us to modify the behaviour
of each step of the build process for Flask as well.
This should result in no functional changes.
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,
});
```

This rationalizes how arguments are passed to and parsed by the build system. To accomplish this, everything that isn't an environment variable from `.metamaskrc` or our CI environment is now passed as an argument on the command line.
Of such arguments, the `entryTask` is still expected as a positional argument in the first position (i.e. `process.argv[2]`), but everything else must be passed as a named argument. We use `minimist` to parse the arguments, and set defaults to preserve existing behavior.
Arguments are parsed in a new function, `parseArgv`, in `development/build/index.js`. They are assigned to environment variables where convenient, and otherwise returned from `parseArgv` to be passed to other functions invoked in the same file.
This change is motivated by our previous inconsistent handling of arguments to the build system, which will grow increasingly problematic as the build system grows in complexity. (Which it will very shortly, as we introduce Flask builds.)
Miscellaneous changes:
- Adds a build system readme at `development/build/README.md`
- Removes the `beta` package script. Now, we can instead call: `yarn dist --build-type beta`
- Fixes the casing of some log messages and reorders some parameters in the build system
This adds an `--omit-lockdown` flag to our build script, which will cause SES `lockdown` to be omitted from the resulting bundle. Useful for development when we don't want the environment to be locked down.
Thanks to @kumavis for the suggestion.
The Firefox e2e tests now use the `.zip` file for testing the
extension. We've found this to produce more similar results to
production, compared to the old method of loading the unzipped
directory.
Passing in a `.zip` file to the Chrome driver didn't seem to work. I
didn't investigate this further to see if it was possible, but I'm not
sure it makes a difference on Chrome anyway.
