About This Skill

What it does

This skill allows you to mix JavaScript and TypeScript code within the same project or file. It enables gradual adoption of TypeScript, allowing developers to introduce type safety incrementally without rewriting entire JavaScript codebases at once. The allowJs compiler option is enabled for this purpose.

When to use it

Migrating a large JavaScript codebase to TypeScript gradually.
Working on projects with existing JavaScript dependencies that are not yet available in TypeScript.
Combining TypeScript modules with legacy JavaScript files.
When you need to quickly prototype something using JavaScript and then refactor it into TypeScript later.

Key capabilities

Enables the allowJs compiler option.
Allows mixing .js and .ts/.tsx files in a project.
Supports gradual TypeScript adoption.

Example prompts

"Can you help me integrate this JavaScript file into my TypeScript project?"
"How do I use allowJs to transition from JavaScript to TypeScript?"
“I have a legacy Javascript library, how can I use it in my Typescript project?”

Tips & gotchas

Ensure your TypeScript configuration (tsconfig.json) includes "allowJs": true. Without this setting, the skill will not function correctly.
Be mindful of potential type errors when mixing JavaScript and TypeScript code; thorough testing is recommended.
