dts-minify


Minifies TypeScript declaration files (.d.ts files).

Strips:

- Non-essential whitespace and newlines.
- Comments, but keeps triple-slash directives.

Use Case

This library is useful for minifying declaration files that won't be read by
humans.

Setup

Deno:

``sh
deno add @david/dts-minify
`

Node:

`sh
npm install dts-minify
`

Example

`ts
import { createMinifier } from "@david/dts-minify"; // dts-minify on npm
import * as ts from "typescript";

// setup (provide a TS Compiler API object)
const minifier = createMinifier(ts);

// minify
const inputText = declare class MyClass {
/**
* Some description.
*/
doSomething(value: number): number;
};
const minifiedText = minifier.minify(inputText);

console.log(minifiedText);
`

Outputs:

`ts
declare class MyClass{doSomething(value:number):number;}
`

#### keepJsDocs

When true, it won't remove the JS docs.

`ts
const minifiedText = minifier.minify(inputText, {
keepJsDocs: true, // false by default
});
`

Outputs:

`ts
declare class MyClass{/**
* Some description.
*/doSomething(value:number):number;}
