Composio Core Files - Cloudflare Workers E2E Test

This package tests @composio/core file operations in Cloudflare Workers environment.

Purpose

Verifies that:

composio.files.upload() throws the expected "not supported in Cloudflare Workers" error
composio.files.download() throws the expected "not supported in Cloudflare Workers" error
The FileToolModifier.workerd.ts is correctly loaded and provides the expected error message when autoUploadDownloadFiles is explicitly enabled
Composio initializes correctly with the default configuration (autoUploadDownloadFiles: false in workerd runtime)
Composio can be explicitly initialized with autoUploadDownloadFiles: false

Endpoints

Endpoint	Description
`GET /`	Lists all available test endpoints
`GET /test/files/upload`	Tests that `files.upload()` throws the expected error
`GET /test/files/download`	Tests that `files.download()` throws the expected error
`GET /test/file-modifier/error-message`	Tests the error when `autoUploadDownloadFiles: true` is explicitly set
`GET /test/auto-upload-disabled`	Tests Composio initialization with explicit `autoUploadDownloadFiles: false`
`GET /test/default-config`	Tests Composio initialization with default configuration (no explicit setting)

Running Tests

bash

# From the package directory
pnpm test:e2e

# Or from the monorepo root
pnpm --filter @e2e-tests/cf-workers-files test:e2e:cloudflare

Environment Variables

Copy .env.example to .env and set your API key:

bash

COMPOSIO_API_KEY=your-composio-api-key

Note: For file operation tests, a dummy API key works since the operations throw errors before making API calls.

Default Configuration

In Cloudflare Workers (workerd runtime), autoUploadDownloadFiles defaults to false.

This means you can initialize Composio without any special configuration:

typescript

const composio = new Composio({
  apiKey: 'your-key',
});
// autoUploadDownloadFiles is false by default in workerd

FileToolModifier Error

If you explicitly set autoUploadDownloadFiles: true and execute a tool with file properties in Cloudflare Workers, the following error is thrown:

File upload/download modifiers are not available on edge runtimes yet.
Please set `autoUploadDownloadFiles: false` or run Composio in another JS runtime (Node.js / Bun).

Best Practice

For edge runtimes, use the default configuration or explicitly set autoUploadDownloadFiles: false:

typescript

const composio = new Composio({
  apiKey: 'your-key',
  autoUploadDownloadFiles: false, // This is the default for workerd
});

Note that with this configuration, file upload/download operations will not be automatically handled.
