Convex Functions let you build the brain of your app. You write queries to fetch data, mutations to change data, and actions to talk to outside services. Each function type has a special job. Queries are fast because they cache results. Mutations keep your data safe with transactions. Actions can call external APIs but cannot touch the database directly.
You also get HTTP actions for webhooks and APIs. Every function needs argument validation and error handling. This skill shows you the right way to write them. It helps you avoid common mistakes and make your app reliable.
Anyone building apps with Convex will benefit. The examples use plain code and clear rules. You will learn to validate inputs, handle errors, and choose the right function for each task.
