Sending a JSON file to Express server using JS

Question

I am fairly new to JS and I have a JSON file that I need to send to my server (Express) that I can then parse and use its contents throughout the web app I\'m building.

Answer 1

Just make sure you're requiring the correct file as a variable and then pass that variable into your res.send!

const data = require('/path/to/data.json')

app.get('/search', function (req, res) {
  res.header("Content-Type",'application/json');
  res.send(JSON.stringify(data));
})

Also, my personal preference is to use res.json as it sets the header automatically.

app.get('/search', function (req, res) {
  res.json(data);
})

EDIT:

The drawback to this approach is that the JSON file is only read once into memory. If you don't want the file read into memory or you're planning on modify the JSON on disk at some point then you should see Ian's Answer
