Advanced TypeScript types for fun and reliability

The main goal of the workshop is to demonstrate various TypeScript features which attendees might or might not be familiar with. These include setting strict types, validating data at runtime and compile time, creating custom type mappings, and exploring type predicates and assertions among other advanced topics.

Participants need a Node runtime, npm installed, and preferably Node version 12.2 or later. A basic understanding of TypeScript is also recommended to follow the workshop effectively.

The workshop is designed to be interactive with participants writing a lot of code themselves, getting involved in breakout rooms for discussions, and performing tasks in groups. This approach helps simulate a real-life coding environment and tackles problem-solving in a collaborative setting.

Zot is used in the workshop to validate data at boundaries, such as inputs from users or data fetched from APIs. It ensures that the data matches expected types and structures, promoting reliability and reducing runtime errors in applications.

Beyond the basic strict mode, the workshop explores several strict settings that are not covered by TypeScript's default strict mode. These include 'noUncheckedIndexedAccess', 'noUnusedLocals', and 'noImplicitReturns', which provide stricter type checking and help catch potential bugs in code.
