Type Declarations

TypeScript type declarations for stdlib.

Installation

npm install @stdlib/types

Usage

/// <reference types="@stdlib/types"/>

import { ArrayLike } from '@stdlib/types/array';

function sum( x: ArrayLike<number> ): number {
    let s = 0.0;
    for ( let i = 0; i < x.length; i++ ) {
        s += x[ i ];
    }
    return s;
}

Type declarations are organized as modules. For example, to use iterator type declarations,

/// <reference types="@stdlib/types"/>

import { Iterator } from '@stdlib/types/iter';

function sum( iter: Iterator ): number {
    let s = 0.0;
    while ( true ) {
        let v = iter.next();
        if ( v.done ) {
            break;
        }
        s += v.value;
    }
    return s;
}

For the complete list of declared modules, see the index.d.ts type declaration file.

Notes

• In order to use included TypeScript declarations, configure your tsconfig.json file accordingly. For example,

  {
    "compilerOptions": {
      ...
      "typeRoots": [ "./path/to/@stdlib/types" ],
      ...
    },
    ...
  }

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
