# Flarum Typescript Config
A standardised `tsconfig.json` for use in Flarum extensions.
## Usage
You'll need to configure a `tsconfig.json` file to ensure your IDE sets up Typescript support correctly.
You need to install this package as a dev dependency to your extension JS:
```properties
npm install --save-dev flarum-tsconfig
yarn add --dev flarum-tsconfig
```
A baseline `tsconfig.json` is provided below that you can modify as needed. This file needs to be copied into your extension's `js` folder for your IDE to apply the correct settings.
```jsonc
{
// Use Flarum's tsconfig as a starting point
"extends": "flarum-tsconfig",
// This will match all .ts, .tsx, .d.ts, .js, .jsx files in your `src` folder
// and also tells your Typescript server to read core's global typings for
// access to `dayjs` and `$` in the global namespace.
"include": ["src/**/*", "../vendor/flarum/core/js/dist-typings/@types/**/*"],
"compilerOptions": {
// This will output typings to `dist-typings`
"declarationDir": "./dist-typings",
"baseUrl": ".",
"paths": {
"flarum/*": ["../vendor/flarum/core/js/dist-typings/*"]
}
}
}
```
You'll also need to ensure that you run `composer update` in your extension's root directory to ensure that a copy of Flarum core is downloaded to your `vendor` folder. Remember that `vendor` should **not** be committed to Git repositories.
