readFile in nodejs with Typescript

I start to learn typescript today, and there's a problem.

Here is the filetree(after compiling):

dist
    index.js
src
    data.txt
    index.ts

Here is ./src/index.ts:

import { readFileSync } from 'fs';

let data = readFileSync('./data.txt');
console.log(data);

After compiling with command "tsc", it creates ./dist/index.js, absolutely the file data.txt cannot be read correctly. How to make it the right path?

Usually you are not supposed to put data in src folder. There are several ways if you really want to do so:

  1. copy data.txt to dist while compiling typescript
  2. use absolute path which could be path.join(__dirname, "../src/data.txt")
  3. Since you already know index.ts is going to be compiled to dist, use "../src/data.txt" directly
