Building locally
- Install Node.js version 14
- If you are using nvm (recommended) running
nvm use
will automatically choose the right node version for you.
- If you are using nvm (recommended) running
- Install Yarn
- Install dependencies:
yarn setup
(not the usual install command) - Copy the
.metamaskrc.dist
file to.metamaskrc
- Replace the
INFURA_PROJECT_ID
value with your own personal Infura Project ID. - If debugging MetaMetrics, you'll need to add a value for
SEGMENT_WRITE_KEY
Segment write key.
- Replace the
- Build the project to the
./dist/
folder withyarn dist
.
Uncompressed builds can be found in /dist
, compressed builds can be found in /builds
once they're built.
See the build system readme for build system usage information.

Development builds
To start a development build (e.g. with logging and file watching) run yarn start
.
To start the React DevTools and Redux DevTools Extension
alongside the app, use yarn start:dev
.
- React DevTools will open in a separate window; no browser extension is required
- Redux DevTools will need to be installed as a browser extension. Open the Redux Remote Devtools to access Redux state logs. This can be done by either right clicking within the web browser to bring up the context menu, expanding the Redux DevTools panel and clicking Open Remote DevTools OR clicking the Redux DevTools extension icon and clicking Open Remote DevTools.
- You will also need to check the "Use custom (local) server" checkbox in the Remote DevTools Settings, using the default server configuration (host
localhost
, port8000
, secure connection checkbox unchecked)
- You will also need to check the "Use custom (local) server" checkbox in the Remote DevTools Settings, using the default server configuration (host
Test site can be used to execute different user flows.
Running Unit Tests and Linting
Run unit tests and the linter with yarn test
. To run just unit tests, run yarn test:unit
.
You can run the linter by itself with yarn lint
, and you can automatically fix some lint problems with yarn lint:fix
. You can also run these two commands just on your local changes to save time with yarn lint:changed
and yarn lint:changed:fix
respectively.
Running E2E Tests
Our e2e test suite can be run on either Firefox or Chrome. In either case, start by creating a test build by running yarn build:test
.
Firefox e2e tests can be run with yarn test:e2e:firefox
.
Chrome e2e tests can be run with yarn test:e2e:chrome
, but they will only work if you have Chrome v79 installed. Update the chromedriver
package to a version matching your local Chrome installation to run e2e tests on newer Chrome versions.
Changing dependencies
Whenever you change dependencies (adding, removing, or updating, either in package.json
or yarn.lock
), there are various files that must be kept up-to-date.
yarn.lock
:- Run
yarn setup
again after your changes to ensureyarn.lock
has been properly updated.
- Run
- The
allow-scripts
configuration inpackage.json
- Run
yarn allow-scripts auto
to update theallow-scripts
configuration automatically. This config determines whether the package's install/postinstall scripts are allowed to run. Review each new package to determine whether the install script needs to run or not, testing if necessary. - Unfortunately,
yarn allow-scripts auto
will behave inconsistently on different platforms. macOS and Windows users may see extraneous changes relating to optional dependencies.
- Run
- The LavaMoat policy files. The tl;dr is to run
yarn lavamoat:auto
to update these files, but there can be devils in the details. Continue reading for more information.- There are two sets of LavaMoat policy files:
- The production LavaMoat policy files (
lavamoat/browserify/*/policy.json
), which are re-generated usingyarn lavamoat:background:auto
.- These should be regenerated whenever the production dependencies for the background change.
- The build system LavaMoat policy file (
lavamoat/build-system/policy.json
), which is re-generated usingyarn lavamoat:build:auto
.- This should be regenerated whenever the dependencies used by the build system itself change.
- The production LavaMoat policy files (
- Whenever you regenerate a policy file, review the changes to determine whether the access granted to each package seems appropriate.
- Unfortunately,
yarn lavamoat:auto
will behave inconsistently on different platforms. macOS and Windows users may see extraneous changes relating to optional dependencies. - Keep in mind that any kind of dynamic import or dynamic use of globals may elude LavaMoat's static analysis. Refer to the LavaMoat documentation or ask for help if you run into any issues.
