Getting Started

Getting started with Pixelbin Backend SDK for Javascript

Installation

npm install @pixelbin/admin --save

Usage

Quick Example

// import the PixelbinConfig and PixelbinClient
const { PixelbinConfig, PixelbinClient } = require("@pixelbin/admin");

// Create a config with you API_TOKEN
const config = new PixelbinConfig({
    domain: "https://api.pixelbin.io",
    apiSecret: "API_TOKEN",
    integrationPlatform: "YourAppName/1.0 (AppPlatform/2.0)", // this is optional
});

// Create a pixelbin instance
const pixelbin = new PixelbinClient(config);

async function getData() {
    try {
        // list the assets stored on your organization's Pixelbin Storage
        const explorer = pixelbin.assets.listFilesPaginator({
            onlyFiles: true,
            pageSize: 5,
        });
        while (explorer.hasNext()) {
            const { items, page } = await explorer.next();
            console.log(page.current); // 1
            console.log(page.hasNext); // false
            console.log(page.size); // 3
            console.log(items.length); // 3
        }
    } catch (err) {
        console.log(err);
    }
}

getData();

Uploader

upload

Uploads a file to PixelBin with greater control over the upload process.

returns: Promise

On Success

Example :

Uploading a buffer

// import the PixelbinConfig and PixelbinClient
const { PixelbinConfig, PixelbinClient } = require("@pixelbin/admin");
const fs = require("fs");

// Create a config with you API_TOKEN
const config = new PixelbinConfig({
    domain: "https://api.pixelbin.io",
    apiSecret: "API_TOKEN",
    integrationPlatform: "YourAppName/1.0 (AppPlatform/2.0)", // this is optional
});

// Create a pixelbin instance
const pixelbin = new PixelbinClient(config);

const buffer = fs.readFileSync("./myimage.png")

const result = await pixelbin.uploader.upload({
  file: buffer,
  name: "myimage",
  path: "folder",
  format: "png",
  tags: [],
  metadata: {},
  overwrite: false,
  filenameOverride: false,
  access: "public-read",
  uploadOptions: {
    chunkSize: 5 * 1024 * 1024 // 5MB
    concurrency: 2, // 2 concurrent chunk uploads
    maxRetries: 1, // 2 retries for errors that can be retried
    exponentialFactor: 1, // exponential factor for retries
  }
});

console.log(result.url)
// "https://cdn.pixelbin.io/v2/mycloudname/original/folder/myimage.png"

Example :

Uploading a stream

// import the PixelbinConfig and PixelbinClient
const { PixelbinConfig, PixelbinClient } = require("@pixelbin/admin");
const fs = require("fs");

// Create a config with you API_TOKEN
const config = new PixelbinConfig({
    domain: "https://api.pixelbin.io",
    apiSecret: "API_TOKEN",
    integrationPlatform: "YourAppName/1.0 (AppPlatform/2.0)", // this is optional
});

// Create a pixelbin instance
const pixelbin = new PixelbinClient(config);

const buffer = fs.createReadStream("./myimage.png")

const result = await pixelbin.uploader.upload({
  file: buffer,
  name: "myimage",
  path: "folder",
  format: "png",
  tags: [],
  metadata: {},
  overwrite: false,
  filenameOverride: false,
  access: "public-read",
  uploadOptions: {
    chunkSize: 5 * 1024 * 1024 // 5MB
    concurrency: 2, // 2 concurrent chunk uploads
    maxRetries: 1, // 2 retries for errors that can be retried
    exponentialFactor: 1, // exponential factor for retries
  }
});

console.log(result.url)
// "https://cdn.pixelbin.io/v2/mycloudname/original/folder/myimage.png"

Integration Platform

The integrationPlatform parameter allows you to customize the User-Agent string in API requests. This helps in identifying the specific application or plugin making the request, useful for analytics and troubleshooting.

How to Use

Include the integrationPlatform in your Pixelbin configuration as shown above. The string should clearly identify your application or plugin and include version details as well as any platform your system is deployed on if applicable.

Syntax : Pixelbin{integration_name}/{integration_version} ({platform_name}/{platform_version})

Security Utils

For generating Signed URLs

Generate a signed PixelBin url

Example:

const { security } = require("@pixelbin/admin");

const signedUrl = security.signURL(
    "https://cdn.pixelbin.io/v2/dummy-cloudname/original/__playground/playground-default.jpeg", // url
    20, // expirySeconds
    "0b55aaff-d7db-45f0-b556-9b45a6f2200e", // accessKey
    "dummy-token", // token
);
// signedUrl
// https://cdn.pixelbin.io/v2/dummy-cloudname/original/__playground/playground-default.jpeg?pbs=8eb6a00af74e57967a42316e4de238aa88d92961649764fad1832c1bff101f25&pbe=1695635915&pbt=0b55aaff-d7db-45f0-b556-9b45a6f2200e

Usage with custom domain url

const { security } = require("@pixelbin/admin");

const signedUrl = security.signURL(
    "https://krit.imagebin.io/v2/original/__playground/playground-default.jpeg", // url
    30, // expirySeconds
    "0b55aaff-d7db-45f0-b556-9b45a6f2200e", // accessKey
    "dummy-token", // token
);
// signedUrl
// https://krit.imagebin.io/v2/original/__playground/playground-default.jpeg?pbs=1aef31c1e0ecd8a875b1d3184f324327f4ab4bce419d81d1eb1a818ee5f2e3eb&pbe=1695705975&pbt=0b55aaff-d7db-45f0-b556-9b45a6f2200e

URL Utils

Pixelbin provides url utilities to construct and deconstruct Pixelbin urls.

urlToObj

Deconstruct a pixelbin url

Returns:

Example:

const { url } = require("@pixelbin/admin");

const pixelbinUrl =
    "https://cdn.pixelbin.io/v2/your-cloud-name/z-slug/t.resize(h:100,w:200)~t.flip()/path/to/image.jpeg";

const obj = url.urlToObj(pixelbinUrl);

Usage with URL Translation Worker

const { url } = require("@pixelbin/admin");

const obj = {
    cloudName: "your-cloud-name",
    zone: "z-slug",
    version: "v2",
    transformations: [],
    filePath: "",
    worker: true,
    workerPath: "resize:h100,w:200/folder/image.jpeg",

// url
// https://cdn.pixelbin.io/v2/your-cloud-name/z-slug/wrkr/resize:h100,w:200/folder/image.jpeg

For Uploading File Buffer

To upload a Buffer, originalFilename must be passed in the options object.

const { Readable } = require("stream");
const res = await pixelbin.assets.fileUpload({
    file: Readable.from(req.file.buffer),
    name: req.body.name,
    options: { originalFilename: req.file.originalname },
    overwrite: true,
});
