Using with Node

Using LINQ To Typescript with Node

Setting Up

Ensure that you're using Current or LTS version of Node

Run npm init to setup the project.

Run npm install linq-to-typescript tslib.

Using with JavaScript

Create index.js with the following,

"use strict";
const linq_to_typescript_1 = require("linq-to-typescript");

const primeNumbers = linq_to_typescript_1.range(2, 10000)
    .select((i) => [i, Math.floor(Math.sqrt(i))])
    .where(([i, iSq]) => linq_to_typescript_1.range(2, iSq).all((j) => i % j !== 0))
    .select(([prime]) => prime)
    .toArray();
console.log(primeNumbers);

then run node index.js

Using with TypeScript

Ensure that you have TypeScript installed npm install typescript -g

Run tsc --init to create the tsconfig.json file

Configuring tsconfig.json

• Update the Typescript configuration file to target es2017. Node supports ES2017.
• Add the ES2017, esnext.asynciterable, and dom library files to be included for compilation. ("lib" element)
• Uncomment the "importHelpers": true line

Add index.ts file with the following,

import { range } from "linq-to-typescript"

const primeNumbers = range(2, 10000)
    .select((i) => [i, Math.floor(Math.sqrt(i))])
    .where(([i, iSq]) =>
        range(2, iSq).all((j) => i % j !== 0))
    .select(([prime]) => prime)
    .toArray()

async function asyncIterable() {
    for await (const i of  range(0, 10).selectAsync(async (x) => x * 2)) {
        console.log(i)
    }
}

asyncIterable()
console.log(primeNumbers)

Run tsc to compile the index.ts to index.js

Run node index.js
