How can I run a specific script in Webflow using npm? I'm new to dependencies and would appreciate any guidance. Thank you!

TL;DR
  • Set up a local folder, initialize with NPM, and install needed packages.
  • Write your script, bundle it using a tool like Webpack, then embed the final JS file into Webflow via the Custom Code section.

To run a specific script in Webflow using NPM, you’ll first need to understand that Webflow itself doesn't directly integrate with NPM. However, you can still use NPM to manage dependencies and build tools outside of Webflow (e.g., for minifying scripts or bundling assets), then embed the final JavaScript into your Webflow project.

Here’s a step-by-step guide to help you run and use an NPM-based script with your Webflow site.

1. Set Up a Local Project Folder

  • Create a folder on your computer for your Webflow-related project.
  • In a terminal or command prompt, navigate to that folder using cd your-folder-name.

2. Initialize NPM and Install Dependencies

  • Run npm init -y to initialize the project and create a package.json file.
  • Install any necessary packages using npm install, e.g.,:
  • npm install gsap for animations,
  • npm install axios for HTTP requests.

3. Create and Run a Script

  • Create a JavaScript file, for example, main.js.
  • In that file, write the logic using the installed package, e.g.:
  • import gsap from 'gsap';
  • gsap.to('.box', { x: 100 });
  • Update the package.json to include a script. Example:
    ```json
    "scripts": {
    "build": "webpack"
    }
    ```

4. Bundle the Script for Webflow

  • Use a bundler like Webpack, esbuild, or Vite to compile your NPM-based scripts into one file.
  • Output the final JS file (e.g., bundle.js).

5. Add Bundled Script to Webflow

  • In Webflow, go to Project Settings > Custom Code or inside a Page's settings.
  • Paste your bundled JS file URL inside <script src="..."></script> tags.
  • If local, upload it to a service like GitHub Pages, Netlify, or an asset host.
  • Example: <script src="https://yourdomain.com/dist/bundle.js" defer></script>

6. Publish & Test on Webflow

  • Publish your Webflow site.
  • Test the functionality to ensure the script runs correctly.

Summary

To use an NPM script with Webflow, create your own local project, install dependencies, bundle your code, and then embed the final JavaScript file into your Webflow project using the Custom Code settings. Webflow itself doesn’t run npm scripts—you build externally and integrate the compiled output.
