Using Node.js (Express) to import a JSON file from a URL

As someone new to node.js, I am attempting to retrieve a json file from a specific url (e.g. 'http://www.example.com/sample_data.json'). My objective is to fetch the file just once when the server initializes and then store it locally on the client side for future manipulation. I attempted

var file = request('http//exmaple.com/sample_data.json')

however, this resulted in an error regarding import modules. Any guidance on how to begin would be greatly appreciated! Many thanks

Answer №1

If I wanted to accomplish that task, I would utilize the request module.

var request = require('request');
request('http//exmaple.com/sample_data.json', function (error, response, body) {
  if (!error && response.statusCode == 200) {
     var importedJSON = JSON.parse(body);
     console.log(importedJSON);
  }
})

Answer №2

Here are a few key points to remember when working with node.js:

1) Make sure to install the necessary modules using npm. For instance, if you're using the 'request' module, run the command "npm install request --save".

2) Remember to require the modules at the beginning of your code. For example, you can use the syntax: var request = require('request');

It's essential to address these steps initially before diving into your project.
