How to Use TinyPNG API in JavaScript

TinyPNG is a popular image compression tool that can help reduce the size of your images without compromising on the image quality. The TinyPNG API extends the functionality of the TinyPNG service, making it possible for developers to integrate the tool into their own applications. In this article, we will take a look at how you can use the TinyPNG API in JavaScript.

Getting Started with the TinyPNG API

Before you can use the TinyPNG API, you will need to sign up for an API key. You can do this by visiting the TinyPNG Developers website at https://tinypng.com/developers. Once you have an API key, you can use it to make API calls.

Installing the TinyPNG API for JavaScript

The TinyPNG API for JavaScript can be installed using npm. To install the package, run the following command:

npm install tinify --save

Using the TinyPNG API in JavaScript

To use the TinyPNG API in JavaScript, you will need to create an instance of the tinify object. Once you have the object, you can use it to compress your images.

Here is an example of how to use the TinyPNG API in JavaScript:

const tinify = require("tinify");
tinify.key = "YOUR_API_KEY";

const source = tinify.fromFile("example.png");
source.toFile("example-compressed.png")

In this example, we first import the tinify package and set the API key. Next, we load the image using the fromFile method and then compress the image using the toFile method.

Using the TinyPNG API with Node.js

To use the TinyPNG API with Node.js, you can use the fs module to read and write image files. Here is an example:

const tinify = require("tinify");
const fs = require("fs");
tinify.key = "YOUR_API_KEY";

const source = tinify.fromBuffer(fs.readFileSync("example.png"));
source.toBuffer((err, resultData) => {
  if (err) throw err;
  fs.writeFileSync("example-compressed.png", resultData);
});

In this example, we first load the tinify and fs packages and set the API key. Next, we read the image file using the readFileSync method and then compress the image using the toBuffer method. Finally, we write the compressed image to file using the writeFileSync method.

Conclusion

In this article, we have looked at how to use the TinyPNG API in JavaScript. We have covered how to sign up for an API key, install the package, and use the API with both Node.js and in the browser. With the TinyPNG API, you can improve the performance of your applications by compressing images and reducing their file size.
