如何在 NodeJS 的 ts 文件中设置环境变量？

Question

I am struggling with the following error:

error TS2591: Cannot find name 'process'. Do you need to install type definitions for node? Try `npm i --save-dev @types/node` and then add 'node' to the types field in your tsconfig.

baseUrl: process.env.TEST

// environment.prod.ts

import 'dotenv/config';

export const environment = {
    production: true,
      baseUrl: process.env.TEST
    };

//.env

TEST=whatever

I've already installed @types/node and dotenv, the problem is the IDE on typescript files is telling me there is something wrong with TEST , what am I missing?

Answer 1

Its not enough to install dotenv package, it's types and use it right after with process.env.TEST

You also have to configure your dotenv package in App.ts or any root file of an application you have

something like this:

dotenv.config({ path: __dirname + `/../.production.env}` })
