One way to provide environment variables when running a script with npm, is to create a file called .npmrc
in the root of the project (same level as package.json
).
Here is an example .npmrc
(note: lowercase):
telegram_token=abc
telegram_chat_id=123
git ignore this file, especially in public repos
I find it useful to have an npm script called node
, which runs node, but by loading the .npmrc
file:
In your package.json
"scripts": {
"node": "node",
...
Then, in your Node.js script, you would read the environment variables with the npm_config_
prefix.
You can run this now with npm run node -- index.js
The index.js
file:
console.log(process.env.npm_config_telegram_token)
> abc
console.log(process.env.npm_config_telegram_chat_id)
> 123
Here is how I personally manage my environments in Node.js.
Example
Below you can find an example using the library simple-telegram-message
:
const { sendMessageFor } = require('simple-telegram-message')
const sendMessage = sendMessageFor(process.env.npm_config_telegram_token, process.env.npm_config_telegram_chat_id)
sendMessage(`Hi from bot!`)
