imgbb-uploader

Lightweight Nodejs module to upload local pictures files to imgbb API and get display URLs in response.
Primary use is letting imgBB handle the hosting & serving of images.

Compatibility:

Node >= 8 ( async/await )
Care: this module uses fs under the hood. It WON'T work outside the node environment !

I want to use this client-side

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

Install

npm install imgbb-uploader

Use with two string params (legacy, LTS)

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");

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'
}

This async function returns a promise:
console.log(imgbbUploader(myKey, myPath)) // Promise { <pending> }
Use await or .then as shown above.

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

Use with options object (more features, yay! )

From version 1.2.0 onward, you can also 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");

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 (POSIX time ftw).
  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)

  Enable this to upload base64-encoded image directly as string. (available from 1.3.0 onward)
  Allows to work with RAM directly for increased performance (skips fs I/O calls).
  Beware: options.imagePath will be ignored as long as options.base64string is defined! 
  */
};

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

This module is tiny & totally unlicensed: to better fit your need, please fork away !
Basic instructions for tweaking

More examples using option object

Using options.base64string:

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

// Some promise of base64 data
const base64str = () =>
  new Promise((resolve) => {
    return setTimeout(() => {
      resolve(
        "iVBORw0KGgoAAAANSUhEUgAAAAIAAAACCAYAAABytg0kAAAAEklEQVR42mNcLVNbzwAEjDAGACcSA4kB6ARiAAAAAElFTkSuQmCC",
      );
    }, 1000);
  });

// Your barebone async function
const myUrl = async (name) => {
  return await imgbbUploader({
    apiKey: "definitely-not-a-valid-key",
    base64string: await base64str(),
    name: 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";
    });
};

myUrl("Dolunay_Obruk-Sama_<3");

This module doesn't support array uploads. For heavy duty, you'll probably have to work with fs.readdir and maybe async forEach. For example, you can create a baseDir.js file wherever it suits you:

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

Then you can require it elsewhere and use something like path.join(myDirpath, "subfolder") to dig into directories programmatically.
Once there you can for example fs.readdir and iterate forEach file of that directory.
See fs documentation and Stack Overflow for more inspiration on the matter.
