How to make your JavaScript library
Create your own Javascript library in 5 easy steps with code examples. Learn how to make your code reusable & efficient.
Creating a JavaScript Library
Creating a JavaScript library can be a rewarding and fun experience. It allows you to create a reusable set of code that can be used in multiple projects and shared with other developers. Here is an example of creating a basic JavaScript library.Step 1: Setup the project
The first step is to setup the project. We need to create a directory for the project and add a few files. Create a directory called "mylibrary" and add an index.html and a src folder. Inside the src folder create a file called "mylibrary.js".mkdir mylibrary cd mylibrary touch index.html mkdir src touch src/mylibrary.js
Step 2: Add the library code
Next, we need to add the source code to the mylibrary.js file. This is the code that will be used in your library. For our example, we will create a simple function that returns the current date.
function getDate() {
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
if(dd<10) {
dd = '0'+dd
}
if(mm<10) {
mm = '0'+mm
}
today = yyyy + '-' + mm + '-' + dd;
return today;
}
Step 3: Adding the library to the HTML page
Now we need to add the library to our HTML page. We can do this by using theStep 4: Using the library
Once the library is added to the HTML page, we can use the getDate() function in our code. For example, we can add an element to the page that displays the current date.
Today's date is
That's it! We've successfully created a basic JavaScript library. With a few more lines of code, you can create a more complex library that can be used in multiple projects.
