I am using ESLinter for a simple node project. Below is the only code I have in index.js:
const express = require('express');
const app = express();
app.get('/', (req, res) => {
res.send({
hi: 'there'
});
});
const PORT = process.env.PORT || 5000;
app.listen(PORT);
I am using VSCode editor. It automatically runs ESLint for JS code.
In the IDE, I see below error for last but one line -
[eslint] 'process' is not defined. (no-undef)
Any Idea what's wrong?
Thanks @FelixKling and @Jaromanda X for quick responses.
I have fixed this with following config for .eslintrc.json file-
{
"env": {
"node": true,
"commonjs": true
},
"extends": "eslint:recommended",
"rules": {
"indent": [
"error",
"tab"
],
"linebreak-style": [
"error",
"unix"
],
"quotes": [
"error",
"single"
],
"semi": [
"error",
"always"
]
},
"parserOptions": {
"ecmaVersion": 2015
}
}
When I got error I had "browser": true instead of "node": true. Simple mistake.
Adding "node": "true" to an existing list of environments will do the job, too
"env": {
"node": true,
"commonjs": true,
"browser": true,
"es6": true
}
Add .eslintrc file to root of your project (if you don't already have one) and define globals to ignore
{
"globals": {
"process": true
}
}
Make sure you use process.env though out the project but only in a single configuration file. Consider adding no-process-envrule.
