This application is a browser extension. There is no ability to run it as a standalone web application.
Each child of the src directory represents the JavaScript context in which it is ran.
When working on the extension, you can run it in development mode which will watch for any file changes and
use react-refresh to update the extension as you work. This gives us near instant reloading of our changes, and
persists the state of the application between changes. To start development mode for the extension, run this command:
yarn devWe bundle a test app to use along with the extension. It gives easy access to the various functions that the extension can do.
In a separate terminal, run:
yarn dev:test-appYou'll need to add it to your browser of choice. Leather only
supports Chromium and Firefox browsers. When you run yarn dev, it will compile the application to the /dist folder
Several testing scripts are available in package.json.
The integration tests expect the extension to be built prior to running. The extension can be built for tests with the command below.
yarn build:testThe integration tests use Playwright, which requires the system to have the browsers it needs. The following command installs everything Playwright needs.
yarn playwright install --with-depsNote that the installed browsers are tied to the version of Playwright being used, and it may be necessary to run the above command again in some situations, such as when upgrading Playwright or switching branches. Read the documentation for more information.
All integration tests can be run using:
yarn test:integrationTo run a suite of tests you can use:
yarn playwright test specs/TEST.spec.ts
yarn playwright test tests/specs --shard=3/8Unit tests can be run with vitest using:
yarn test:unitSee instructions on Leather.io to install from source
Alternatively, the following steps can be taken by technical users with the latest version of node installed on their machines.
Run the following from within this repository's root directory if you've pulled it with Git:
yarn && yarn prepare && yarn buildThe extension is now built in the ./dist folder.
To build the extension in Firefox mode, the TARGET_BROWSER=firefox variable needs to be set.
yarn && yarn prepare && TARGET_BROWSER=firefox yarn buildNote that when building in a clean environment, some code may vary between this and the submitted build. This is because some variables are set within the scope of the production build's CI.
