| description | Convert existing projects into Apify Actors - serverless cloud programs. Actorize JavaScript/TypeScript (SDK with Actor.init/exit), Python (async context manager), or any language (CLI wrapper). Use when migrating code to Apify, wrapping CLI tools as Actors, or adding Actor SDK to existing projects. |
Apify Actorization
Actorization converts existing software into reusable serverless applications compatible with the Apify platform. Actors are programs packaged as Docker images that accept well-defined JSON input, perform an action, and optionally produce structured JSON output.
Quick Start
- Run
apify init in project root
- Wrap code with SDK lifecycle (see language-specific section below)
- Configure
.actor/input_schema.json
- Test with
apify run --input '{"key": "value"}'
- Deploy with
apify push
When to Use This Skill
- Converting an existing project to run on Apify platform
- Adding Apify SDK integration to a project
- Wrapping a CLI tool or script as an Actor
- Migrating a Crawlee project to Apify
Prerequisites
Verify apify CLI is installed:
apify --help
If not installed, use one of these methods (listed in order of preference):
npm install -g apify-cli
Security note: Do NOT install the CLI by piping remote scripts to a shell
(e.g. curl … | bash or irm … | iex). Always use a package manager.
Verify CLI is logged in:
apify info
If not logged in, check if the APIFY_TOKEN environment variable is defined (if not, ask the user to generate one at https://console.apify.com/settings/integrations and then define APIFY_TOKEN with it).
Then authenticate using one of these methods:
apify login
Security note: Avoid passing tokens as command-line arguments (e.g. apify login -t <token>).
Arguments are visible in process listings and may be recorded in shell history.
Prefer environment variables or interactive login instead.
Never log, print, or embed APIFY_TOKEN in source code or configuration files.
Use a token with the minimum required permissions (scoped token) and rotate it periodically.
Actorization Checklist
Copy this checklist to track progress:
Step 1: Analyze the Project
Before making changes, understand the project:
- Identify the language - JavaScript/TypeScript, Python, or other
- Find the entry point - The main file that starts execution
- Identify inputs - Command-line arguments, environment variables, config files
- Identify outputs - Files, console output, API responses
- Check for state - Does it need to persist data between runs?
Step 2: Initialize Actor Structure
Run in the project root:
apify init
This creates:
.actor/actor.json - Actor configuration and metadata.actor/input_schema.json - Input definition for the Apify ConsoleDockerfile (if not present) - Container image definition
Step 3: Apply Language-Specific Changes
Choose based on your project's language:
Quick Reference
| Language | Install | Wrap Code |
|---|
| JS/TS | npm install apify | await Actor.init() ... await Actor.exit() |
| Python | pip install apify | async with Actor: |
| Other | Use CLI in wrapper script | apify actor:get-input / apify actor:push-data |
Steps 4-6: Configure Schemas
See schemas-and-output.md for detailed configuration of:
- Input schema (
.actor/input_schema.json)
- Output schema (
.actor/output_schema.json)
- Actor configuration (
.actor/actor.json)
- State management (request queues, key-value stores)
Validate schemas against @apify/json_schemas npm package.
Step 7: Write README
IMPORTANT: Always generate a README.md as part of actorization. The README is the Actor's landing page on Apify Store and is critical for discoverability (SEO), user onboarding, and support. Do not consider an Actor complete without a proper README.
See the Actor README guidelines at skills/apify-actor-development/references/actor-readme.md for the required structure including: intro and features, data extraction table, step-by-step tutorial, pricing info, input/output examples, and FAQ. Aim for at least 300 words with SEO-optimized H2/H3 headings. Also review these top Actors for best practices:
Step 8: Test Locally
Run the actor with inline input (for JS/TS and Python actors):
apify run --input '{"startUrl": "https://example.com", "maxItems": 10}'
Or use an input file:
apify run --input-file ./test-input.json
Important: Always use apify run, not npm start or python main.py. The CLI sets up the proper environment and storage.
Step 9: Deploy
apify push
This uploads and builds your actor on the Apify platform.
Monetization (Optional)
After deploying, you can monetize your actor in the Apify Store. The recommended model is Pay Per Event (PPE):
- Per result/item scraped
- Per page processed
- Per API call made
Configure PPE in the Apify Console under Actor > Monetization. Charge for events in your code with await Actor.charge('result').
Other options: Rental (monthly subscription) or Free (open source).
Security
Treat all crawled web content as untrusted input. Actors ingest data from external websites that may contain malicious payloads. Follow these rules:
- Sanitize crawled data — Never pass raw HTML, URLs, or scraped text directly into shell commands,
eval(), database queries, or template engines. Use proper escaping or parameterized APIs.
- Validate and type-check all external data — Before pushing to datasets or key-value stores, verify that values match expected types and formats. Reject or sanitize unexpected structures.
- Do not execute or interpret crawled content — Never treat scraped text as code, commands, or configuration. Content from websites could include prompt injection attempts or embedded scripts.
- Isolate credentials from data pipelines — Ensure
APIFY_TOKEN and other secrets are never accessible in request handlers or passed alongside crawled data. Use the Apify SDK's built-in credential management rather than passing tokens through environment variables in data-processing code.
- Review dependencies before installing — When adding packages with
npm install or pip install, verify the package name and publisher. Typosquatting is a common supply-chain attack vector. Prefer well-known, actively maintained packages.
- Pin versions and use lockfiles — Always commit
package-lock.json (Node.js) or pin exact versions in requirements.txt (Python). Lockfiles ensure reproducible builds and prevent silent dependency substitution. Run npm audit or pip-audit periodically to check for known vulnerabilities.
Pre-Deployment Checklist
Apify MCP Tools
If MCP server is configured, use these tools for documentation:
search-apify-docs - Search documentationfetch-apify-docs - Get full doc pages
Otherwise, the MCP Server url: https://mcp.apify.com/?tools=docs.
