typescript-plugin-toml

A typescript language service plugin providing support for toml files.

Usage

npm i -D typescript-plugin-const-json # yarn add -D typescript-plugin-const-json

And then add this to tsconfig.json.

{
  "compilerOptions": {
    "plugins": [{ "name": "typescript-plugin-const-json" }]
  }

.const.json

If the file name ends with .const.json, the typings will become as if you are using as const.

For example it will be like below.

test.toml and test.const.toml

key = 'val'

index.ts

import test from './test.toml'
import testConst from './test.const.toml'

type Test = typeof test // { key: string }
type TestConst = typeof testConst // { readonly key: 'val' }
