The cosmiconfig-typescript-loader package is designed to enable the loading of TypeScript files by cosmiconfig, a library used for finding and loading configuration files for Node.js projects. This loader allows cosmiconfig to read and parse configurations written in TypeScript, providing a seamless integration for projects that prefer TypeScript for configuration.

What are cosmiconfig-typescript-loader's main functionalities?

Loading TypeScript configuration files

This feature allows cosmiconfig to load and parse TypeScript files as configuration files. The code sample demonstrates how to configure cosmiconfig to use the cosmiconfig-typescript-loader for '.ts' files, enabling the loading of TypeScript configurations.

const { cosmiconfig } = require('cosmiconfig');
const { cosmiconfigTypescriptLoader } = require('cosmiconfig-typescript-loader');

const explorer = cosmiconfig('yourModuleName', {
  searchPlaces: ['config.ts', 'otherConfig.ts'],
  loaders: {
    '.ts': cosmiconfigTypescriptLoader
  }
});

explorer.search().then((result) => {
  console.log(result.config);
});

⚙️🚀 TypeScript config file support for cosmiconfig

`@endemolshinegroup/cosmiconfig-typescript-loader`

This package serves as a drop in replacement for @endemolshinegroup/cosmiconfig-typescript-loader. At the time of publishing this, endemolshinegroup is not maintaining the original package. I can only assume this is to do with the fact that Endemol Shine Group was purchased and absorbed by another business. This discontinuation of development efforts towards the original package left any open issues and pull requests unresolved.

This new package resolves the following original issues:

#134: "Doesn't work with Cosmiconfig sync API"
#147: "doesn't provide typescript, requested by ts-node"
#155: "Misleading TypeScriptCompileError when user's tsconfig.json "module" is set to "es2015""

Usage

Simply add TypeScriptLoader to the list of loaders for the .ts file type:

import { cosmiconfig } from "cosmiconfig";
import TypeScriptLoader from "cosmiconfig-typescript-loader";

const moduleName = "module";
const explorer = cosmiconfig("test", {
  searchPlaces: [
    "package.json",
    `.${moduleName}rc`,
    `.${moduleName}rc.json`,
    `.${moduleName}rc.yaml`,
    `.${moduleName}rc.yml`,
    `.${moduleName}rc.js`,
    `.${moduleName}rc.ts`,
    `.${moduleName}rc.cjs`,
    `${moduleName}.config.js`,
    `${moduleName}.config.ts`,
    `${moduleName}.config.cjs`,
  ],
  loaders: {
    ".ts": TypeScriptLoader(),
  },
});

const cfg = explorer.load("./");

Or more simply if you only support loading of a TypeScript based configuration file:

import { cosmiconfig } from "cosmiconfig";
import TypeScriptLoader from "cosmiconfig-typescript-loader";

const moduleName = "module";
const explorer = cosmiconfig("test", {
  loaders: {
    ".ts": TypeScriptLoader(),
  },
});

const cfg = explorer.load("./amazing.config.ts");
