+# Default build configuration by Grafana
+
+**This is an auto-generated directory and is not intended to be changed! ⚠️**
+
+The `.config/` directory holds basic configuration for the different tools
+that are used to develop, test and build the project. In order to make it updates easier we ask you to
+not edit files in this folder to extend configuration.
+
+## How to extend the basic configs?
+
+Bear in mind that you are doing it at your own risk, and that extending any of the basic configuration can lead
+to issues around working with the project.
+
+### Extending the ESLint config
+
+Edit the `.eslintrc` file in the project root in order to extend the ESLint configuration.
+
+**Example:**
+
+```json
+{
+  "extends": "./.config/.eslintrc",
+  "rules": {
+    "react/prop-types": "off"
+  }
+}
+```
+
+---
+
+### Extending the Prettier config
+
+Edit the `.prettierrc.js` file in the project root in order to extend the Prettier configuration.
+
+**Example:**
+
+```javascript
+module.exports = {
+  // Prettier configuration provided by Grafana scaffolding
+  ...require('./.config/.prettierrc.js'),
+
+  semi: false,
+};
+```
+
+---
+
+### Extending the Jest config
+
+There are two configuration in the project root that belong to Jest: `jest-setup.js` and `jest.config.js`.
+
+**`jest-setup.js`:** A file that is run before each test file in the suite is executed. We are using it to
+set up the Jest DOM for the testing library and to apply some polyfills. ([link to Jest docs](https://jestjs.io/docs/configuration#setupfilesafterenv-array))
+
+**`jest.config.js`:** The main Jest configuration file that extends the Grafana recommended setup. ([link to Jest docs](https://jestjs.io/docs/configuration))
+
+#### ESM errors with Jest
+
+A common issue found with the current jest config involves importing an npm package which only offers an ESM build. These packages cause jest to error with `SyntaxError: Cannot use import statement outside a module`. To work around this we provide a list of known packages to pass to the `[transformIgnorePatterns](https://jestjs.io/docs/configuration#transformignorepatterns-arraystring)` jest configuration property. If need be this can be extended in the following way:
+
+```javascript
+process.env.TZ = 'UTC';
+const { grafanaESModules, nodeModulesToTransform } = require('./jest/utils');
+
+module.exports = {
+  // Jest configuration provided by Grafana
+  ...require('./.config/jest.config'),
+  // Inform jest to only transform specific node_module packages.
+  transformIgnorePatterns: [nodeModulesToTransform([...grafanaESModules, 'packageName'])],
+};
+```
+
+---
+
+### Extending the TypeScript config
+
+Edit the `tsconfig.json` file in the project root in order to extend the TypeScript configuration.
+
+**Example:**
+
+```json
+{
+  "extends": "./.config/tsconfig.json",
+  "compilerOptions": {
+    "preserveConstEnums": true
+  }
+}
+```
+
+---
+
+### Extending the Webpack config
+
+Follow these steps to extend the basic Webpack configuration that lives under `.config/`:
+
+#### 1. Create a new Webpack configuration file
+
+Create a new config file that is going to extend the basic one provided by Grafana.
+It can live in the project root, e.g. `webpack.config.ts`.
+
+#### 2. Merge the basic config provided by Grafana and your custom setup
+
+We are going to use [`webpack-merge`](https://github.com/survivejs/webpack-merge) for this.
+
+```typescript
+// webpack.config.ts
+import type { Configuration } from 'webpack';
+import { merge } from 'webpack-merge';
+import grafanaConfig from './.config/webpack/webpack.config';
+
+const config = async (env): Promise<Configuration> => {
+  const baseConfig = await grafanaConfig(env);
+
+  return merge(baseConfig, {
+    // Add custom config here...
+    output: {
+      asyncChunks: true,
+    },
+  });
+};
+
+export default config;
+```
+
+#### 3. Update the `package.json` to use the new Webpack config
+
+We need to update the `scripts` in the `package.json` to use the extended Webpack configuration.
+
+**Update for `build`:**
+
+```diff
+-"build": "webpack -c ./.config/webpack/webpack.config.ts --env production",
++"build": "webpack -c ./webpack.config.ts --env production",
+```
+
+**Update for `dev`:**
+
+```diff
+-"dev": "webpack -w -c ./.config/webpack/webpack.config.ts --env development",
++"dev": "webpack -w -c ./webpack.config.ts --env development",
+```
