If you are interested in developer trends you should check out my new newsletter at: unzip.dev
I'm assuming you are using nodejs with a version later than 13.
First, you will need to change your package.json
to:
{
"name": "api",
"version": "1.0.0",
"type": "module",
...
}
(The type
is the important part).
Now you can freely use imports, here is an express start with dotenv
import dotenv from "dotenv"
import express from "express"
dotenv.config()
const app = express()
const port = process.env.PORT || 5000
app.get('/', (req, res) => {
res.send('Hello World!')
})
app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`)
})
Notes:
Having dotenv
gives you the ability to add environment variables into .env
files and use them easily in your express (in this case) app.
