simple URL validator with Typescript for Deno 🦕

Usag:

Permssion Flags (Require):

  • --allow-net : for API Requests To Tinify Server
  • --allow-read : for read images and post it to server for compression process
  • --allow-write : for create new Image after compression process

Authentication:

You must have a valid Tinify API key (you can get your own from here)

If you need to save the compressed image to a server :

import { Tinify } from "https://deno.land/x/tinify/mod.ts";
// Read file frome the server
const img = await Deno.readFile('test/Uncompressed-image.jpg') ; 

// Image URL
const imgURL = "https://www.gravatar.com/avatar/ea52ed86c481ca2816b8403acdbc9169?s=512"

// Replace <API_KEY> with your tinify api key for more info visite https://tinypng.com/developers
const tinify = new Tinify({
    api_key:"<API_KEY>"
})

const compressedImage:any = await (await tinify.compress(img)) // Image compression process from Uint8Array encode (file)
const compressedImageFromURl:any = await (await tinify.compress(imgURL)) // Image compression process from url

console.log(await compressedImage.saveTo('test/Compressed-image.jpg')) // save new compressed image in the server

Output:

{
  input: { size: 402678, type: "image/jpeg" },
  output: {
    size: 168904,
    type: "image/jpeg",
    width: 1920,
    height: 1280,
    ratio: 0.4195,
    url: "https://api.tinify.com/output/r72h1n39uugta3p2yybnqukdj3rbwhv6"
  },
  compressedImagePath: "test/Compressed-image.jpg"
}

If you need to convert the compressed image to base64 string :

const compressedImage:any = await (await tinify.compress(img)) // Image compression process from Uint8Array encode (file) or url


console.log(await compressedImage.toBase64())

Output:

{
  input: { size: 402678, type: "image/jpeg" },
  output: {
    size: 168904,
    type: "image/jpeg",
    width: 1920,
    height: 1280,
    ratio: 0.4195,
    url: "https://api.tinify.com/output/r72h1n39uugta3p2yybnqukdj3rbwhv6"
  },
  base64Image: "base64 string of the compressed image"
}
