What is CustomJS and how does it work?
CustomJS is a node type in Latenode that lets you write and run JavaScript code directly in your automation scenarios. You can use full JavaScript syntax, import npm packages, and process data from previous nodes without needing external tools or API keys.
When should I use CustomJS instead of built-in nodes?
Use CustomJS when you need custom logic that standard nodes don't provide, like complex data transformation, conditional calculations, or connecting to APIs that Latenode hasn't pre-built. It's faster than requesting a custom integration and gives you full control over your automation.
How can I use CustomJS to connect apps and automate workflows in Latenode?
Add a CustomJS node to your scenario after a trigger or another action. Write code to transform data, call external APIs, or process information from connected apps. CustomJS runs as part of your scenario execution, so data flows seamlessly between your apps and your custom logic on the same canvas.
About CustomJS
CustomJS is a JavaScript code snippet manager that lets you inject custom scripts into any website. You can write, organize, and run JavaScript snippets on specific domains or globally across all sites. The tool supports script scheduling, automatic execution on page load, and syncing your snippets across devices. Use it to modify page behavior, automate repetitive tasks, test code directly in the browser, or customize the appearance and functionality of websites you visit regularly.
