This feature is available for premium tier and above customers. Efficiently reuse JavaScript code via snippets.

This premium feature empowers you to craft reusable JavaScript code that can be seamlessly referenced throughout your apps. These snippets are app-specific and can be utilised wherever JavaScript selection is available.

Accessing snippets

To access this feature, navigate to any drawer opened by clicking on a lightning bolt icon. Within this drawer, you will initially be presented with text (Handlebars syntax) by default. To utilise JavaScript snippets, select the JavaScript option provided. Subsequently, a new icon <\> should appear on the right-hand side. Clicking on this icon will enable you to view and start creating your JavaScript snippets. The GIF below will demonstrate where to find and access these snippets.

Creating a snippet

At the outset, you have two options since you don't have any snippets yet. You can either click the prominent Create snippet button or the + icon located in the top-right corner of the drawer. Both options will enable you to start creating your first snippet.

After clicking either of the above methods, the snippet drawer will now be open. An image illustrating this can be found below.

Within this drawer, several key elements are worth noting. Firstly, there's the Name field. Utilise this field to assign a descriptive name to your snippet, such as oddOrEven for a function that checks if a value is odd or even.

Additionally, below this field is where you would write your JavaScript function that you wish to reuse throughout your app. Below is a simple function example that checks whether a passed-in value is odd or even, returning this information in text format as the output.

return function(n) {
    if (n % 2 === 0) {
        return "even";
    } else {
        return "odd";

After you have finished entering your snippet's code, click the 'Save' button. This action will redirect you back to the previous screen, displaying the new snippet that you have created.

Using a snippet

Now that you have set up a snippet, you can use it similarly to how helpers functions are used. Simply click on a snippet within the list, and it will be inputted to your drawer. The only additional step you'll need to do is provide it with an argument. Using the previous example of oddOrEven, it would look something like this: snippets.oddOrEven(argument). This will pass whatever value is set into the snippet function, execute it, and return a result based on the outcome of the value passed in. Within Budibase you should be able to use a binding and pass a value into the snippet function.
