JavaScript


ToolJet workflows let you import npm packages into your workflow so that every JavaScript node can use them. Once a package is added, it is bundled and available across all JavaScript nodes in that workflow version.

info

External library support for workflows is available on Enterprise Edition plans.

Adding Packages​

  1. Open your workflow in the editor.
  2. Click the Packages icon in the left sidebar to open the package manager panel.
  3. Type a package name (e.g., lodash) in the search field — results are fetched from the npm registry.
  4. Select the package and version you want to install, then click Add.
  5. The package is added to the workflow's dependency list and a bundle build starts automatically.

You can add multiple packages before the bundle finishes building. The bundle regenerates with all current dependencies.

Using Packages in JavaScript Nodes​

Once the bundle status is Ready, you can import the packages directly in any JavaScript node:

import lodash from 'lodash';
import { v4 as uuidv4 } from 'uuid';

const grouped = lodash.groupBy(getOrders.data, 'status');

return {
    requestId: uuidv4(),
    summary: grouped
};

Packages are available to all JavaScript nodes in the workflow — you don't need to import them separately per node.

Removing Packages​

  1. Open the package manager panel.
  2. Click the Remove icon next to the package you want to remove.
  3. The bundle regenerates automatically without the removed package.
