node.js - Read and write a text file in typescript

Question

How should I read and write a text file from typescript in node.js? I am not sure would read/write a file be sandboxed in node.js, if not, i believe there should be a way in accessing file system.

Answer 1

believe there should be a way in accessing file system.

Include node.d.ts using npm i @types/node. And then create a new tsconfig.json file (npx tsc --init) and create a .ts file as followed:

import * as fs from 'fs';
fs.readFileSync('foo.txt','utf8');

You can use other functions in fs as well : https://nodejs.org/api/fs.html
