Flow Type Development Environment

A development utility that sets up an automatic Flow type transformation environment for a Node.js project, allowing developers to execute Flow-typed JavaScript files seamlessly without manual build steps.

Capabilities

Configure automatic type transformation

• It registers a transformation hook that automatically processes required modules @test
• It enables transformation for files without explicit Flow pragmas when configured @test

Execute Flow-typed modules

• It successfully executes a module with Flow type annotations after registering the hook @test
• It executes multiple Flow-typed modules with different type annotations @test

Apply custom file filtering

• It transforms only files matching a custom include pattern @test
• It excludes files matching a custom exclude pattern from transformation @test

Implementation

@generates
