Atomic Build Status

A tiny, Promise-based vanilla JS Ajax/HTTP plugin with great browser support.

Getting Started

Compiled and production-ready code can be found in the dist directory. The src directory contains development code.

1. Include Atomic on your site.

There are two versions of Atomic: the standalone version, and one that comes preloaded with a polyfill for ES6 Promises, which are only supported in newer browsers.

If you're including your own polyfill or don't want to enable this feature for older browsers, use the standalone version. Otherwise, use the version with the polyfill.

Direct Download

You can download the files directly from GitHub.

<script src="path/to/atomic.polyfills.min.js"></script>

CDN

You can also use the jsDelivr CDN. I recommend linking to a specific version number or version range to prevent major updates from breaking your site. Smooth Scroll uses semantic versioning.

<!-- Always get the latest version -->
<!-- Not recommended for production sites! -->
<script src="https://cdn.jsdelivr.net/gh/cferdinandi/atomic/dist/atomic.polyfills.min.js"></script>
 
<!-- Get minor updates and patch fixes within a major version -->
<script src="https://cdn.jsdelivr.net/gh/cferdinandi/atomic@4/dist/atomic.polyfills.min.js"></script>
 
<!-- Get patch fixes within a minor version -->
<script src="https://cdn.jsdelivr.net/gh/cferdinandi/atomic@4.0/dist/atomic.polyfills.min.js"></script>
 
<!-- Get a specific version -->
<script src="https://cdn.jsdelivr.net/gh/cferdinandi/atomic@4.0.0/dist/atomic.polyfills.min.js"></script>

NPM

You can also use NPM (or your favorite package manager).

npm install atomicjs

2. Make your Ajax request.

Pass in the requested URL, and optionally, your desired options. Request method defaults to GET.

Use .then() with a callback to handle successful responses, and catch() to handle errors.

// A basic GET request
atomic('https://some-url.com')
    .then(function (response) {
        console.log(response.data); // xhr.responseText
        console.log(response.xhr);  // full response
    })
    .catch(function (error) {
        console.log(error.status); // xhr.status
        console.log(error.statusText); // xhr.statusText
    });
 
// A POST request
atomic('https://some-url.com', {
    method: 'POST'
})
    .then(function (response) {
        console.log(response.data); // xhr.responseText
        console.log(response.xhr);  // full response
    })
    .catch(function (error) {
        console.log(error.status); // xhr.status
        console.log(error.statusText); // xhr.statusText
    });

ES6 Modules

Atomic does not have a default export, but does support CommonJS and can be used with native ES6 module imports.

import('/path/to/atomic.polyfills.min.js')
    .then(function () {
        atomic('https://some-url.com')
            .then(function (response) {
                console.log(response.data); // xhr.responseText
                console.log(response.xhr);  // full response
            })
            .catch(function (error) {
                console.log(error.status); // xhr.status
                console.log(error.statusText); // xhr.statusText
            });
    });

It uses a UMD pattern, and should also work in most major module bundlers and package managers.

Working with the Source Files

If you would prefer, you can work with the development code in the src directory using the included Gulp build system. This compiles, lints, and minifies code.

Dependencies

Make sure these are installed first.

Quick Start

  1. In bash/terminal/command line, cd into your project directory.
  2. Run npm install to install required files.
  3. When it's done installing, run one of the task runners to get going:
    • gulp manually compiles files.
    • gulp watch automatically compiles files when changes are made and applies changes using LiveReload.
    • gulp test runs unit tests.

Options and Settings

Atomic includes smart defaults and works right out of the box. You can pass options into Atomic through the ajax() function:

atomic('https://some-url.com', {
    method: 'GET', // {String} the request type
    username: null, // {String} an optional username for authentication purposes
    password: null, // {String} an optional password for authentication purposes
    data: {}, // {Object|Array|String} data to be sent to the server
    headers: { // {Object} Adds headers to your request: request.setRequestHeader(key, value)
        'Content-type': 'application/x-www-form-urlencoded'
    },
    responseType: 'text', // {String} the response type (https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/responseType)
    timeout: null, // {Integer} the number of milliseconds a request can take before automatically being terminated
    withCredentials: false // {Boolean} If true, send credentials with request (https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/withCredentials)
});

Canceling a Request

While Promises can't be canceled, Atomic does have an internal API for aborting your XHR request using the cancel() method.

In order to work, you must set your atomic() method to a variable without .then() methods. They can be called on the variable after setting.

// Setup your request
var xhr = atomic('https://some-url.com');
 
// Handle responses
xhr.then(function (response) {
        console.log(response.data); // xhr.responseText
        console.log(response.xhr);  // full response
    })
    .catch(function (error) {
        console.log(error.status); // xhr.status
        console.log(error.statusText); // xhr.statusText
    });
 
// Cancel your request
xhr.cancel();

Migrating from Atomic 3

New Features

  • Atomic is now Promise-based, and supports chaining with .then() and .catch().
  • For simple requests, you can now just pass in a URL to atomic() like you would with the Fetch API. You no longer need to pass in an object with the url parameter.

Breaking Changes

  • You must pass in a URL as the first argument. The URL as an options parameter is no longer support.
  • You now pass arguments directly into atomic(). The atomic.ajax() method no longer exists.
  • The .success(), .error(), and .always() callbacks have been removed. Use .then() and .catch() instead.
  • JSONP support has been removed.

You can still download Atomic 3 and earlier on the releases page.

Browser Compatibility

Atomic works in all modern browsers, and IE8 and above.

The standalone version provides native support for all modern browsers. Use the .polyfills version (or include your own) to support IE.
