pronto-flow no longer falls in my interestes and I cannot give it any time in keeping it updated. With flow ever changing the logic for parsing the changing json output of that tool is a moving target. I've also made the decision to use TypeScript over Flow for future JavaScript projects.

Feel free to fork and take the project in a new direction. You could also contact me to unarchive it if you are willing to maintain it.

Pronto runner for flow, a static type checker for javascript. What is Pronto?

Uses official flow executable installed by npm.

You'll need to install flow by yourself with npm. If flow is in your PATH, everything will simply work, otherwise you have to provide pronto-flow your custom executable path (see below).

Configuring flow via .flowconfig will work just fine with pronto-flow.

pronto-flow can be configured by placing a .pronto_flow.yml inside the directory where pronto is run.

Following options are available:

Example configuration to call custom flow executable:

# .pronto_flow.yml
flow_executable: '/my/custom/node/path/.bin/flow'
cli_options: '--show-all-errors'
