FlowTees

Purpose

This tool provides support in the conversion process of converting a Flow component to TypeScript. It takes the trivial work out of the conversion. These are just floaties to help you but won't totally convert your component.

Note: Tool is specifically made for Atlaskit.

Features

• Renames files to tsx/ts
• Ignores node_modules
• Removing flow decorators (@flow, $StringLitteral, $FlowFixMe)
• Remove type keyword from exports and imports
• Renames type keyword to interface keyword when applicable and can handle extends
• Configures package.json and creates tsconfig.json files

Usage

FlowTees is a command line application, called flowtees, the application is used before beginning the conversion process. It assumes that no work has been started on the component yet.

To begin, run the following command:

$ flowtees [directory/to/component]

e.g. say you are converting the select component, then the command would look like this:

$ flowtees ~/src/atlaskit-mk-2/packages/core/select

The program will begin analyzing the js files in the directory and do a dry run to find only compatible files to convert. The compatible files will be listed in green while incompatible files will be shown in red.

After processing the files, you will get a prompt asking whether you want to also include the build config files for TS. This helps to create the appropriate tsconfig.json files in the component directory and also modify the the package.json file so it points to the correct index.ts file.

Installation

$ pip install flowtees
