Angular is a popular framework for developing web applications. If we want to use JWTs in our Angular application, we can use the jwt-decode library to decode the JWTs and extract the information they contain.<\/p>\n\n\n\n<h4>What is jwt decode?<\/h4>\n\n\n\n<p>jwt-decode is a JavaScript library designed to make it easier to decode JWTs in simple JavaScript applications. It allows developers to analyze JWTs and extract the payload data they contain without complicated logic.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>To use the jwt-decode library in our Angular application, Let us follow these steps:<\/p>\n\n\n\n<h5><span class=\"has-inline-color has-vivid-cyan-blue-color\"><strong>1 &#8211; <\/strong>\u00a0<strong>Installation of the library<\/strong><\/span><\/h5>\n\n\n\n<pre class=\"wp-block-code\"><code>npm install jwt-decode\r<\/code><\/pre>\n\n\n\n<h5><span class=\"has-inline-color has-vivid-cyan-blue-color\"><strong>2 &#8211; Importing the library<\/strong><\/span><\/h5>\n\n\n\n<pre class=\"wp-block-code\"><code>import * as jwtDecode from 'jwt-decode';\r<\/code><\/pre>\n\n\n\n<h5><span class=\"has-inline-color has-vivid-cyan-blue-color\"><strong>3 &#8211; Decode JWT<\/strong><\/span><\/h5>\n\n\n\n<p>Let us  use the jwt-decode function to decode a JWT and retrieve the information it contains:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>const token = 'IhrJWTTokenHier'; \/\/ Replace 'YourJWTTokenHere' with your actual JWT\n\r\nconst decodedToken = jwtDecode(token);\r\n\r\nconsole.log(decodedToken);\r\n<\/code><\/pre>\n\n\n\n<p>The decodedToken variable now contains the extracted information from the JWT.<\/p>\n\n\n\n<p>We can now use the data contained in decodedToken in our Angular application, for example to display the logged in user or otherwise interact with the JWT data.<\/p>\n\n\n\n<h4>Conclusion<\/h4>\n\n\n\n<p>The jwt-decode library is a useful tool for easily processing JWTs in Angular applications.
