Centralize tsconfig.json

[compulim]

Changelog Entry

Changed

• Added internal package @msinternal/botframework-webchat-tsconfig to centralize TypeScript configuration files, in PR #5539, by @compulim

Description

Added new @msinternal/botframework-webchat-tsconfig for centralizing TypeScript configuration files and pave way for convergence.

Design

Naming

Instead of naming the current config as "strictest", prefer "current" because the configuration is not "purely strict", it's "strict plus some Web Chat-specific configurations."

Setting types to empty array

By default, TypeScript will load all node_modules/@types/*. It would allow before/test/after in production code.

We are setting types: [] to explicitly setting the types to empty. The package would need to set their types library accordingly. For example, core is empty, while component is dom-speech-recognition.

However, we would add types using triple reference to test files.

Specific Changes

• Added new @msinternal/botframework-webchat-tsconfig package
• Unified all production-related tsconfig.json to the new package
• Added new features/cssModules configuration file
• Added <reference types="jest" /> to test files
• Added <reference types="node" /> to CommonJS files

• I have added tests and executed them locally
• I have updated CHANGELOG.md
• I have updated documentation
