# `@total-typescript/tsconfig`
`tsconfig.json` can seem extremely scary. But really, it's only 2 or 3 decisions you need to make.
This package makes those decisions even easier. Based on my [TSConfig Cheat Sheet](https://www.totaltypescript.com/tsconfig-cheat-sheet).
## Setup
1. Install:
```bash
npm install --save-dev @total-typescript/tsconfig
```
2. Choose which `tsconfig.json` you need from the [list](#list-of-tsconfigs) below.
3. Add it to your `tsconfig.json`:
```jsonc
{
// I'm building an app that runs in the DOM with an external bundler
"extends": "@total-typescript/tsconfig/bundler/dom/app"
}
```
## List of TSConfigs
The tricky thing about `tsconfig.json` is there is _not_ a single config file that can work for everyone. But, with two or three questions, we can get there:
### Are You Using `tsc` To Turn Your `.ts` Files Into `.js` Files?
#### Yes
If yes, use this selection of configs:
```jsonc
{
// My code runs in the DOM:
"extends": "@total-typescript/tsconfig/tsc/dom/app", // For an app
"extends": "@total-typescript/tsconfig/tsc/dom/library", // For a library
"extends": "@total-typescript/tsconfig/tsc/dom/library-monorepo", // For a library in a monorepo
// My code _doesn't_ run in the DOM (for instance, in Node.js):
"extends": "@total-typescript/tsconfig/tsc/no-dom/app", // For an app
"extends": "@total-typescript/tsconfig/tsc/no-dom/library", // For a library
"extends": "@total-typescript/tsconfig/tsc/no-dom/library-monorepo" // For a library in a monorepo
}
```
#### No
If no, you're probably using an external bundler. Most frontend frameworks, like Vite, Remix, Astro, Nuxt, and others, will fall into this category. If so, use this selection of configs:
```jsonc
{
// My code runs in the DOM:
"extends": "@total-typescript/tsconfig/bundler/dom/app", // For an app
"extends": "@total-typescript/tsconfig/bundler/dom/library", // For a library
"extends": "@total-typescript/tsconfig/bundler/dom/library-monorepo", // For a library in a monorepo
// My code _doesn't_ run in the DOM (for instance, in Node.js):
"extends": "@total-typescript/tsconfig/bundler/no-dom/app", // For an app
"extends": "@total-typescript/tsconfig/bundler/no-dom/library", // For a library
"extends": "@total-typescript/tsconfig/bundler/no-dom/library-monorepo" // For a library in a monorepo
}
```
## Options Not Covered:
### `jsx`
If your app has JSX, you can set the `jsx` option in your `tsconfig.json`:
```json
{
"extends": "@total-typescript/tsconfig/bundler/dom/app",
"compilerOptions": {
"jsx": "react-jsx"
}
}
```
### `outDir`
Mostly relevant for when you're transpiling with `tsc`. If you want to change the output directory of your compiled files, you can set the `outDir` option in your `tsconfig.json`:
```json
{
"extends": "@total-typescript/tsconfig/tsc/node/library",
"compilerOptions": {
"outDir": "dist"
}
}
```
### Framework-Specific Options
I don't yet cover framework-specific options, like `vite`, `next`, `remix`, etc. With enough persuasion, I might add them in the future.
## Why Not Use `@tsconfig/bases`?
The [`@tsconfig/bases`](https://github.com/tsconfig/bases) package is a great resource for TypeScript configurations. However, I disagree with the idea that there is a single "recommended" configuration that works for everyone.
Also, I wanted a set of `tsconfig.json` files that I controlled so I could use them to keep my [Total TypeScript Course Repos](https://github.com/total-typescript) up to date.
