flowtypify generates flowtype definitions from a given JSON Schema. This enables you to type-check the contract your app is working against. Whenever you update the schema, regenerate the flowtype definitions and flow will tell you about breaking changes.
Version-wise its an early Proof of Concept, but the testsuite already covers most of the features I've seen in the wild so far.
fowtypify will parse the JSON schemas and output the types to
--write enabled, a file with the same basename plus
.flow.js will be created for each supplied schema.
npm install --save-dev flowtypify ./node_modules/.bin/flowtypify --write src/schematas/*.json
Yepp, that's, apart from the lack of any optimizations in
flowtypify, due to your schema not having
additionalProperties: false set on object definitions you have.
Everything in test/scenarios works, the following does not work, yet ;)
$idfields (no support for
$idas of JSON Schema Core 9.2 at all, yet)
