+
+[![Build
+Status](https://api.travis-ci.com/edx/frontend-build.svg?branch=master)](https://travis-ci.com/edx/frontend-build)
+![npm\_version](https://img.shields.io/npm/v/@openedx/frontend-build.svg)
+[![Codecov](https://img.shields.io/codecov/c/github/edx/frontend-build)](https://codecov.io/gh/edx/frontend-build)
+[![license](https://img.shields.io/npm/l/@openedx/frontend-build.svg)](https://github.com/edx-unsupported/frontend-base/blob/master/LICENSE)
+
+## Purpose
+
+The purpose of this package is to provide a common sense foundation and
+setup for frontend projects including:
+
+-   linting (eslint)
+-   testing (jest)
+-   development server (webpack-dev-server)
+-   build (webpack)
+
+This package can serve as a single dev dependency replacing a large
+number of dev and build dependencies. It aims to provide common sense
+defaults that should be good for most edX projects out of the box, but
+can extended or overridden where needed.
+
+## Cloning and Startup
+
+``` {.}
+1. Clone your new repo:
+
+  ``git clone https://github.com/openedx/frontend-build.git``
+
+2. Use node v18.x.
+
+  The current version of the micro-frontend build scripts support node 18.
+  Using other major versions of node *may* work, but this is unsupported.  For
+  convenience, this repository includes an .nvmrc file to help in setting the
+  correct node version via `nvm <https://github.com/nvm-sh/nvm>`_.
+
+3. Install npm dependencies:
+
+  ``cd frontend-build && npm ci``
+```
+
+## Usage
+
+CLI commands are structured: `fedx-scripts <targetScript> <options>`.
+Options are passed on to the target script, so refer to each target
+script\'s CLI documentation to learn what options are available. Example
+package.json:
+
+    {
+       "scripts": {
+          "build": "fedx-scripts webpack",
+          "i18n_extract": "fedx-scripts formatjs extract",
+          "lint": "fedx-scripts eslint --ext .jsx,.js .",
+          "precommit": "npm run lint",
+          "snapshot": "fedx-scripts jest --updateSnapshot",
+          "start": "fedx-scripts webpack-dev-server --progress",
+          "test": "fedx-scripts jest --coverage --passWithNoTests",
+          "serve": "fedx-scripts serve"
+       },
+       "dependencies": {
+          ...
+       },
+       "devDependencies": {
+          "@openedx/frontend-build": "1.0.0"
+       }
+    }
+
+## Extending or Overriding Config Presets
+
+This package contains a set of configuration presets:
+
+-   webpack-prod (or webpack)
+-   webpack-dev (or webpack-dev-server)
+-   webpack-dev-stage (for running development apps against stage apis)
+-   babel
+-   babel-preserve-modules
+-   jest
+-   eslint
+
+If you need to extend or modify a configuration you can add your own
+configuration files, either by extending frontend-build\'s configuration
+files or supplying your own wholesale.
+
+Method 1: Extend base config (babel.config.js):
+
+    const { createConfig } = require('@openedx/frontend-build');
+    module.exports = createConfig('babel', {
+       /* option overrides or extensions */
+    });
+
+Method 2: Custom manipulations (babel.config.js):
+
+    const { getBaseConfig } = require('@openedx/frontend-build');
+    const config = getBaseConfig('babel');
+
+    /* Custom config manipulations */
+
+    module.exports = config;
+
+Frontend build will look in the following locations for configuration
+files in your project.
+
+-   eslint: `<project_root>/.eslintrc.js`
+-   jest: `<project_root>/jest.config.js`
+-   babel: `<project_root>/babel.config.js`
+-   webpack-prod: `<project_root>/webpack.prod.config.js`
+-   webpack-dev-server: `<project_root>/webpack.dev.config.js`
+
+You may specify custom config file locations via the command line if you
+prefer a different location. Example package.json:
+
+    {
+       "scripts": {
+          "build": "fedx-scripts webpack --config ./config/webpack.config.js",
+          "start:stage": "fedx-scripts webpack-dev-server --config webpack.dev-stage.config.js",
+          ...
+       }
+    }
+
+Note, specifying a custom config location for babel may cause issues
+with other tools in frontend-build. eslint, jest, webpack, and
+webpack-dev-server configuration presets rely upon the babel config and
+resolve the location of the config file according to the default
+locations described above. If you need to move the babel config file to
+a custom location, you may also need to customize references to its
+location in other configuration files. Please reach out to the FedX team
+if you need to do this and are running into problems.
+
+## Local module configuration for Webpack
+
+
+The development webpack configuration allows engineers to create a
+\"module.config.js\" file containing local module overrides. This means
+that if you\'re developing a new feature in a shared library
+(\@edx/frontend-platform, \@openedx/paragon, etc.), you can add the local
+location of that repository to your module.config.js file and the
+webpack build for your application will automatically pick it up and use
+it, rather than its node\_modules version of the file.
+
+**NOTE: This module.config.js file should be added to your**
+[.gitignore]{.title-ref}.
+
+An example module.config.js file looks like the following. You can copy
+this into your application to use local versions of paragon and
+frontend-platform:
+
+    module.exports = {
+      /*
+      Modules you want to use from local source code.  Adding a module here means that when this app
+      runs its build, it'll resolve the source from peer directories of this app.
+
+      moduleName: the name you use to import code from the module.
+      dir: The relative path to the module's source code.
+      dist: The sub-directory of the source code where it puts its build artifact.  Often "dist".
+      */
+      localModules: [
+        { moduleName: '@openedx/brand', dir: '../src/brand-openedx' }, // replace with your brand checkout
+        { moduleName: '@openedx/paragon/scss/core', dir: '../src/paragon', dist: 'scss/core' },
+        { moduleName: '@openedx/paragon/icons', dir: '../src/paragon', dist: 'icons' },
+        { moduleName: '@openedx/paragon', dir: '../src/paragon', dist: 'dist' },
+        { moduleName: '@edx/frontend-platform', dir: '../src/frontend-platform', dist: 'dist' },
+      ],
+    };
+
+## Steps
+
+1.  Copy the `module.config.js` into your frontend app repository,
+    modifying it as necessary.
+2.  Run `npm install && npm run build` within any shared NPM package you
+    want to use locally.
+3.  Restart your app.
+
+## Notes
+
+-   The \"dir\" and \"dist\" keys give you granular control over the
+    shape of your repository\'s distribution. Paragon, for instance,
+    needs two separate entries to pick up both JS and SCSS imports.
+-   The directory location `../src` (relative to the root of your
+    frontend app repository) is recommended for shared NPM package
+    repositories, since it will work whether or not you are running your
+    frontend via devstack. If you are *not* running your frontend via
+    devstack, then you can place your shared libraries anywhere in your
+    file system, updating the \"dir\" key accordingly. To learn more,
+    see [this devstack ADR on local
+    packages](https://github.com/openedx/devstack/tree/master/docs/decisions/0005-frontend-package-mounts.rst).
+-   This mechanism uses Webpack resolve aliases, as documented here:
+    <https://webpack.js.org/configuration/resolve/#resolvealias>
+
+## Override default .env.development environment variables with .env.private
+
+In some situations, you may want to override development environment
+variables defined in .env.development with private environment variables
+that should never be checked into a repository. For example, a
+.env.development file may contain secrets for a third-party service
+(e.g., Algolia) that you\'d like to use during development but want to
+ensure these secrets are not checked into Git.
+
+You may create a [.env.private]{.title-ref} with any overrides of the
+environment settings configured in [.env.development]{.title-ref}.
+
+**Note: .env.private should be added to your project\'s .gitignore so it
+does not get checked in.**
+
+## Serving a production Webpack build locally
+
+In some scenarios, you may want to run a production Webpack build
+locally. To serve a production build locally:
+
+1.  Create an `env.config.js` file containing the configuration for
+    local development, with the exception of `NODE_ENV='production'`.
+2.  Run `npm run build` to build the production assets. The output
+    assets will rely on the local development configuration specified in
+    the prior step.
+3.  Add an NPM script `serve` to your application\'s `package.json`
+    (i.e., `"serve": "fedx-scripts serve"`).
+4.  Run `npm run serve` to serve your production build assets. It will
+    attempt to run the build on the same port specified in the
+    `env.config.js` file.
+
+## Development
+
+This project leverages the command line interface for webpack, jest,
+eslint, and babel. Because of this, local development can be tricky. The
+easiest way to do local development on this project is to either run
+scripts inside the project in example or to test with an existing
+project you can do the following:
+
+1.  Delete the node\_modules directories in the host project:
+    `rm -rf node_modules/`
+2.  Move frontend-build inside the host project and delete its node
+    modules folder
+    `mv ../frontend-build ./ && rm -rf frontend-build/node_modules`
+3.  Install the development version of frontend-build
+    `npm i --save-dev @openedx/frontend-build@file:./frontend-build`.

+## Reporting Security Issues
+
+Please do not report security issues in public. Please email
+<[email protected]>.
+
+## Optimization
+
+To increase optimization by reducing unused CSS, you can set
+`USE_PURGECSS=true` in `.env` or as ENV var in the corresponding MFE.
+However, note that doing this will increase build time by 30%. It\'s
+thus not recommended to use this option during development. On the other
+hand, enabling PurgeCSS will increase browser performance for the end
+user by as much as 20% (as measured by
+[lighthouse](https://developer.chrome.com/docs/lighthouse/overview/)).
+Operators are encouraged to do so for production deployments.
+
+For more information about optimizing MFEs, refer to the [issue
+\#138](https://github.com/openedx/wg-frontend/issues/138) in the
+wg-frontend repository.
