Pixelbin Core SDK helps you integrate Pixelbin with your Frontend JS Application.
npm install @pixelbin/core --save
// Import the Pixelbin class
import Pixelbin from "@pixelbin/core";
// Create your instance
const pixelbin = new Pixelbin({
cloudName: "demo",
zone: "default", // optional
});
// Import transformations
import Pixelbin, { transformations } from "@pixelbin/core";
const EraseBg = transformations.EraseBg;
const Basic = transformations.Basic;
// Create a new instance. If you have't (see above for the details)
const pixelbin = new Pixelbin({
/*...*/
});
// Create EraseBg.bg transformation
let t1 = EraseBg.bg();
// Create resize transformation
const t2 = Basic.resize({ height: 100, width: 100 });
// create a new image
const demoImage = pixelbin.image("path/to/image"); // File Path on Pixelbin
// Add the transformations to the image
demoImage.setTransformation(t1.pipe(t2));
// Get the image url
console.log(demoImage.getUrl());
// output
// https://cdn.pixelbin.io/v2/your-cloud-name/z-slug/erase.bg()~t.resize(h:100,w:100)/path/to/image
Add the this distributable in a script tag
<script src="pixelbin.v7.0.0.js"></script>
// Pixelbin is available in the browser as `Pixelbin` on the window object
const pixelbin = new Pixelbin({ cloudName: "demo", zone: "default" });
// create an image with the pixelbin object
const image = pixelbin.image("demoImage.jpeg");
// create a transformation
let t = Pixelbin.transformations.Basic.resize({ height: 100, width: 100 });
// add Transformations to the image
image.setTransformation(t);
// get the url
image.getUrl();
// output
// https://cdn.pixelbin.io/v2/demo/default/t.resize(h:100,w:100)/demoImage.jpeg
The SDK provides a upload
utility to upload images directly from the browser with a presigned url.

A transformation is an operation or a list of operations that can be performed on an image. Please refer list of supported transformations for details.
// import a resize transformation
import Pixelbin, { transformations } from "@pixelbin/core";
const { resize } = transformations.Basic;
// create the resize transformation
const t = resize({ height: 100, width: 100 });
Multiple transformations can be chained by using and
on the created transformation object
// import a resize transformation
import Pixelbin, { transformations } from "@pixelbin/core";
const { resize, flip } = transformations.Basic;
// create the basic transformations
const t1 = resize({ height: 100, width: 100 });
const t2 = flip();
const t3 = t1.pipe(t2);
Image class represents an image on Pixelbin.
//To use the url translation worker feature, call image method on the pixelbin object whilst passing `worker` as true;
const image = pixelbin.image("path/to/image", { worker: true });
//To create an Image, call image method on the pixelbin object;
const image = pixelbin.image("path/to/image");
Transformations can be set on an image by using setTransformation
on the image object.
image.setTransformation(t);
Note: Transformations won't be applied to the worker URLs generated from the SDK.
To get the url of the image with the applied transformations, use the getUrl
on the image object.
image.getUrl();
