Deno 2.2 Improves Dependency Management and Expands Node.js Compatibility
Deno 2.2 enhances Node.js compatibility, improves dependency management, adds OpenTelemetry support, and expands linting and task automation for developers.
Maltypart is a simple multipart request builder.
It is very similar to HTML5 FormData, but offers a bit more control over fields and serialization.
Maltypart is a good fit if your app needs to work with multipart form submissions, but you don't want to couple networking logic to your HTML. It supports a few nice additions that FormData doesn't offer, and can serialize Strings, Files, Elements and more.
Creating a new RequestBody:
// Pull in the dependency however you wish: AMD, CJS, Node and globals are all supported
var RequestBody = require('maltypart').RequestBody;
// Create a new multipart body:
var request = new RequestBody();
Appending Strings:
// request is from the first example
request.append({
// String values get serialized with the default content-type, application/octet-stream:
some_key : "some value",
// Passing an Object or Array to append() lets you specify multiple fields at once
second_key : "second value"
});
Appending Typed Content:
request.append('example_image', {
// Specify an Object with "contentType" and "data" properties to set your own content-type:
contentType : "image/png",
// Base64-encoded data as a String:
data : "iVBORw0KGgoAAAANSUhEUgAAABAAAAAQAQMAAAAlPW0iAAAABlBMVEUAAAD"
+ "///+l2Z/dAAAAM0lEQVR4nGP4/5/h/1+G/58ZDrAz3D/McH8yw83NDDe"
+ "NGe4Ug9C9zwz3gVLMDA/A6P9/AFGGFyjOXZtQAAAAAElFTkSuQmCC"
// You can also pass a maltypart.RequestField instead of a POJO.
});
Appending a File:
request.append('some_file', new File(), function() {
// file added.
});
Using with XMLHttpRequest:
// A standard XHR
var xhr = new XMLHttpRequest();
xhr.open('POST', '/upload', true);
// Set the request's content-type appropriately:
xhr.setRequestHeader('Content-Type', request.getContentType());
// Set the multipart-encoded body:
xhr.send( request.getData() );
Via node / browserify:
var maltypart = require('maltypart');
Via AMD / requirejs:
define(['maltypart'], function(maltypart) {
});
Via globals / script tag:
<script src="maltypart.js"></script>
<script>
maltypart; // now it's exposed as a "maltypart" global
</script>
Installation via Bower: (Recommended)
bower install maltypart
