typescript-config

Opinionated reusable Typescript configurations, assuming:

A monorepo setup (*)
Transpile using a bundler
Strict rules
Use of src and dist directories
Use of ~/ as path alias for src

(*) Use the single-*.json variants if you do not use a monorepo setup.

Warning

At the time of writing, not all tooling correctly interprets the extended config.

Next.js will require you to explicitly defined "includes". Give it "src" and it will inject its types on startup.
TSUP will not understand the tsconfig if you ask it to generate type definitions. I use tsc to generate the types, as demonstrated in mono-ts.

Install

pnpm i @codecompose/typescript-config -D

...or the equivalent for your package manager.

Usage

{
  "extends": "@codecompose/typescript-config/single-react-library.json"
}

Available Configurations

base
library
react-library
service
nextjs
single-library
single-react-library

For something else, like a CLI or E2E app you can probably just use the base.json configuration.

Assumptions and Recommendations

Source maps are not enabled, because we assume that your bundler will handle that.

All configurations have incremental set to true. In my experience, it can happen that builds get stuck in limbo and you need to delete the tsbuildinfo file to get things going again. For this reason I recommend adding the following script to your manifest based on del-cli:
