| # Apps | |
| This directory exists to hold a variety of projects that can produce independent, binary-like outputs deployed elsewhere. Typically not published to NPM or built on `yarn start`. | |
| For packages that we might publish as NPM packages, see [`/packages`](../packages). | |
| ## Adding a new app? | |
| If you want to add a new project into this directory, then add a new directory and follow [monorepo -documentation](../docs/guide/monorepo.md). | |
| ## Building | |
| Apps (unlike packages) are not built on Calypso's `yarn`. | |
| You must manually build apps by running: | |
| ```bash | |
| cd apps/app-name | |
| yarn build | |
| # Or any other command in the app's package.json | |
| # E.g. for the FSE plugin dev & sync command: | |
| yarn dev --sync | |
| ``` | |
| ## Validating package.json | |
| `package.json` is linted using ESLint. Run `yarn eslint apps/*/package.json` to validate them. | |
| If you need exceptions to linting rules, add a `./eslintrc.js` file to your app and disable the relevant rules. | |
