Start Implementing APIs in Anypoint Code Builder (ACB) with MySQL + Docker (Part 3)

Ready to move beyond scaffolding? In this hands-on tutorial, we’ll start implementing real API logic in Anypoint Code Builder (ACB) — MuleSoft’s next-gen IDE — using a MySQL database running in Docker. You’ll learn how to: - Set up a MySQL DB with Docker - Connect your ACB project to the database - Organize flows and subflows cleanly - Use DataWeave to generate SQL queries and responses - Structure your project for clean, scalable MuleSoft apps ⚠️ You’ll implement one flow with me, then get some homework to complete the rest — so you’ll walk away with real ACB skills, not just theory. 🧰 Tools used: - Anypoint Code Builder (in VS Code) - Docker + Docker Compose - MySQL (in Docker) - DataWeave 2.0 📂 Source Code & Scripts: GitHub repo → https://github.com/alexandramartinez/todo-api-impl docker-compose.yml - https://gist.github.com/alexandramartinez/3174ad0bc44ed1c7031e479522968a66 create-table-template.sql - https://gist.github.com/alexandramartinez/1531f62f4fdab02056c74d8df7963d03 get-all-tasks.xml - https://gist.github.com/alexandramartinez/7afb5fb85bb1e9425fe7f77e2587cd7a get-all-tasks-request.dwl - https://gist.github.com/alexandramartinez/88723e3d977e854b5390cc863ccd9328 get-all-tasks-response.dwl - https://gist.github.com/alexandramartinez/594c0e5e68babcebee89bc48dd9ed871 🧠 Need help with ACB?
