If not, to install npm, run the following command: Bash Copy the code sudo apt install npm Debugging in Node.js The next step is debugging. One strategy that helped me a lot was to use the to receive more detailed logs for many modules.
Take, for example, a basic express server like this: JavaScript Copy the code const app = require('express')(); const bodyParser = require('body-parser'); app.use(bodyParser.json()); // for parsing application/json app.use(bodyParser.urlencoded({ extended: true })); // for parsing application/x-www-form-urlencoded app.post('/', (req, res, next) => { console.log(req); }); app.listen(3000); Run it with the DEBUG variable set to *: JavaScript Copy the code DEBUG=* node server.
js You will receive detailed logs that look like this: The magic behind it is a lightweight module called debug. When you want to use it, you just initialize it with a "namespace". You can then connect to that namespace. If someone wants to see the output, they just need to enable the namespace in the DEBUG variable.
