imgbb-uploader

Lightweight Nodejs module to upload pictures to imgBB (or other chevereto-based APIs) and get display URLs in response.
Primary use is letting imgBB handle the hosting & serving of images.

Install

npm install imgbb-uploader

Compatibility:

Node >= 8 ( Promises/await ) ESM projects are supported from 1.5 onward Care: this module uses fs under the hood. It WON'T work outside the node environment !

Formats supported by ImgBB API: .jpg, .png,.bmp,.gif, base64, url.

We also support Chevereto v3 & v4!

Did you know? imgBB is based on Chevereto, a software written by rodber that you can easily host yourself.

Upload to imgBB with two string params (legacy)

I) Get a free API key from imgbb ( estimated time ~1 minute )
II) Put that in an environment variable
III) imgbbUploader takes exactly two String arguments : your API key, and the path to your image :

const imgbbUploader = require("imgbb-uploader");
/* or use import in ESM projects:
import { imgbbUploader } from "imgbb-uploader"; 
*/

imgbbUploader("your-imgbb-api-key-string", "path/to/your/image.png")
  .then((response) => console.log(response))
  .catch((error) => console.error(error));

`.then((response) => console.log(response))` output example :

{
  id: '26Sy9tM',
  title: '5e7599f65f27',
  url_viewer: 'https://ibb.co/26Sy9tM',
  url: 'https://i.ibb.co/z5FrMR2/5e7599f65f27.png',
  display_url: 'https://i.ibb.co/z5FrMR2/5e7599f65f27.png',
  size: 260258,
  time: '1609336605',
  expiration: '0',
  image: {
    filename: '5e7599f65f27.png',
    name: '5e7599f65f27',
    mime: 'image/png',
    extension: 'png',
    url: 'https://i.ibb.co/z5FrMR2/5e7599f65f27.png'
  },
  thumb: {
    filename: '5e7599f65f27.png',
    name: '5e7599f65f27',
    mime: 'image/png',
    extension: 'png',
    url: 'https://i.ibb.co/26Sy9tM/5e7599f65f27.png'
  },
   medium: {
   filename: '5e7599f65f27.png',
    name: '5e7599f65f27',
    mime: 'image/png',
    extension: 'png',
    url: 'https://i.ibb.co/14kK0tt/5e7599f65f27.png'
  },
  delete_url: 'https://ibb.co/26Sy9tM/087a7edaaac26e1c940283df07d0b1d7'
}

Note about imgBB API: the medium Object will only be returned for .png and base64 files !

With options object (more features, yay! )

From version 1.2.0 onward, you can pass an options object as param.
Use it to customize filename and/or a set duration after which the image will be deleted, cf their docs.

The key you'll use for your image depends on its nature. One of these must be defined:

imagePath in case of a local file
imageUrl in case of an URL string
base64string in case of base64-encoded image

const imgbbUploader = require("imgbb-uploader");
/* or use import in ESM projects:
import { imgbbUploader } from "imgbb-uploader"; 
*/

const options = {
  apiKey: process.env.IMGBB_API_KEY, // MANDATORY

  imagePath: "./your/image/path", // OPTIONAL: pass a local file (max 32Mb)

  name: "yourCustomFilename", // OPTIONAL: pass a custom filename to imgBB API

  expiration: 3600 /* OPTIONAL: pass a numeric value in seconds.
  It must be in the 60-15552000 range.
  Enable this to force your image to be deleted after that time. */,

  imageUrl: "https://placekitten.com/500/500", // OPTIONAL: pass an URL to imgBB (max 32Mb)

  base64string:
    "iVBORw0KGgoAAAANSUhEUgAAAAIAAAACCAYAAABytg0kAAAAEklEQVR42mNcLVNbzwAEjDAGACcSA4kB6ARiAAAAAElFTkSuQmCC",
  // OPTIONAL: pass base64-encoded image (max 32Mb)
};

imgbbUploader(options)
  .then((response) => console.log(response))
  .catch((error) => console.error(error));

Basic instructions for tweaking

Another example: handling buffer with option object

const imgbbUploader = require("imgbb-uploader");

// Some buffer we need to upload
const data = "definitely-not-an-image-binary";

// Some promise of base64 data
const bufferToBase64 = (buffer) =>
  new Promise((resolve) => {
    const buff = new Buffer(buffer);
    const base64string = buff.toString("base64"); // https://nodejs.org/api/buffer.html#buftostringencoding-start-end
    return setTimeout(() => {
      resolve(base64string);
    }, 1000);
  });

// Some async function
const getDisplayUrl = async (buffer, name = "Default-filename") => {
  return await imgbbUploader({
    apiKey: "definitely-not-a-valid-key",
    base64string: await bufferToBase64(buffer),
    name,
  })
    .then((res) => {
      console.log(`Handle success: ${res.url}`);
      return res.url;
    })
    .catch((e) => {
      console.error(`Handle error: ${e}`);
      return "http://placekitten.com/300/300";
    });
};

const myUrl = getDisplayUrl(data, "Dolunay_Obruk-Sama_<3");

Working with directories/arrays

This module don't and won't directly support array uploads. Only you can pick the best solution for your usecase.
For example, to upload local directories of pictures, I enjoy working with fs.readdir.
I usually create an imagesDir.js file wherever it suits me:

module.exports = require("path").join(__dirname);

Then require that elsewhere and use path.join(imagesDir, relevantSubfolder) to dig into directories.
Once there, iterate using fs.readdir and forEach as needed.
