Documentation for npm package that has been published

Recently, I created my very first npm package using TypeScript. However, when I tried to use this package in another project, I realized that I wasn't getting the expected code completion and it was challenging to work with it without proper support.

I believe the solution lies in creating a declaration file (.d.ts) and including it in the package, but I am struggling to do it correctly.

Even after searching online resources and tutorials, I haven't been able to resolve this issue effectively.

The current state of my 'typings.d.ts' file is as follows:

export declare function Slider(props: SliderProps): void;

The module properties are stored in a separate 'types.ts' file, which is distinct from the main module itself.

Any assistance or guidance on how to rectify this problem would be greatly appreciated.

Here is a snippet from my package.json file:

{
    "main": "node_modules/expo/AppEntry.js",
    "name": "react-native-range-slider-expo",
    "description": "range slider",
    "license": "MIT",
    ...
}

And here is an excerpt from my tsconfig.json file:

{
    "compilerOptions": {
        "allowSyntheticDefaultImports": true,
        "jsx": "react-native",
        "lib": [
            "dom",
            "esnext"
        ],
        ...
}

Answer №1

You can streamline the process of creating your type declaration file without manual intervention.

All you need is to configure tsconfig.json and package.json accordingly:

Simply include the following line in tsconfig.json:

{
  "compilerOptions": {
    "declaration": true
  },
}

Ensure that the declaration path is accurately specified in package.json:

"types": "dist/main.d.ts", // assuming main.ts serves as your entry point

Lastly, remember to eliminate any redundant typings.d.ts files from your src directory.
