Installation

Using pnpm:

pnpm add -D @kikiutils/tsconfigs

You can also use yarn, npm, or bun.

Usage

The base configuration is tsconfig.base.json. You can extend it directly or pick one that matches your desired module and target.

Here's an example of a typical tsconfig.json setup:

{
  "extends": "@kikiutils/tsconfigs/esnext/es2022.json",
  "compilerOptions": {
    "declaration": true,
    "declarationDir": "./dist",
    "declarationMap": true,
    "emitDeclarationOnly": true
  },
  "include": ["./src"]
}

The extends path is structured as:

@kikiutils/tsconfigs/<module>/<target>.json

For example, to use CommonJS as the module and ES2021 as the target, set:

"extends": "@kikiutils/tsconfigs/commonjs/es2021.json"

For unit testing with Jest, you can extend the shared Jest config:

"extends": "@kikiutils/tsconfigs/jest.json"

[!NOTE] All paths and file names are lowercase.

🍞 If you're using the Bun runtime, simply use:

"extends": "@kikiutils/tsconfigs/bun.json"
