Res.status is particularly handy when building functionality around catching errors: fetch('').Node.js has announced that they are introducing support for fetch() as an experimental module with v17.5 and it will be widely available for use with the v18 release. Res.json() // parse via JSON (=> Promise) The response object contains much more than just the response body JSON: fetch('') We can chain together as many of these statements as we want. Note that we are avoiding callback hell by keeping logic that utilizes the response JSON in our then() arrow functions. If needed, the fetch() method also accepts a credentials parameter for authentication. That's more like it: now we're passing headers and a JSON body. "client_secret": "876JHG76UKFJYGVHf867rFUTFGHCJ8JHV"įetch(url, ) Here's how we'd make a more complicated (and realistic) POST call: const url ='' From we generate JSON from the request body and print the result to the console.Ĭhances are you're not going to get much value out of any request without passing headers, parameters, or a body to the target endpoint. Without specifying a method, node-fetch assumes we're making a GET request. Indeed, that's all it takes a base level. We'll start with the most basic GET request possible: const fetch = require('node-fetch') In the JS file we'd like to make a request, we can reference node-fetch using require(): const fetch = require('node-fetch') index.js Creating a node-fetch Request
#Nodejs fetch install#
Start a Node project and install node-fetch: npm install -save node-fetch Install node-fetch When used on the client side, isomorphicfetch works by first importing the es6-promise polyfill. isometric-fetch mimics the syntax of node-fetch, but impressively works on both the client and server-side.
The other request library worth mentioning is isomorphic-fetch, which is intended to be a drop-in replacement for node-fetch.
To put it simply: it's straightforward, and the only one that actually works out of the box with Webpack without absurd configuration nonsense. Who is gunslinging API requests to the point where we need this many options to pipe or parallel API requests anyway?Īfter using all of these libraries, node-fetch is the weapon of choice for today. Don't get me started with async libraries with 40 different methods for chaining requests. httpis a bit primitive, request breaks when building with Webpack, r2 seems like a pointless clone, and so on. Like everything in Javascript, there are way too many packages doing the same thing and solving the same problem. Considering how deep I've gone down the GraphQL rabbit hole myself, this may be the last chance to bother writing about REST at all. Hopefully, those who have lost their way might find something to take from it. I want to provide an alternative to using AJAX calls when interacting with REST APIs to clear my conscious of ever enabling bad behavior in the first place. I would have assumed any post with the word "React" would immediately explode, when in reality people are more interested in using Handlebars with ExpressJS (I'm not proud of that post by the way, please don't read it). That demographic makes up significantly less than 10-20% of the active workforce. While we content publishers sling Medium posts from our ivory towers, we quickly create a perception of what "everybody" is doing, but it turns out "everybody" only includes individuals who are exceptionally visible.
Maintaining a blog of tutorials has taught me a lot about the gap between perception and reality. The only cool thing about JQuery is who can remove it from their legacy stack the fastest, which begs the question: why is the third most popular page on this site an old post about JQuery? JQuery themselves have proclaimed JQuery to be dead.
#Nodejs fetch free#
If you're the type of person to read technical Javascript posts in your free time (you are), you don't need me to tell you that JQuery is dead.
