SaltyCrane Cheat Sheets — Notes on JavaScript and web development

Flow Type Cheat Sheet

Flow is a static type checker for JavaScript. This is a list of Flow types generated from the source code in https://github.com/facebook/flow/tree/v0.56.0/ The script to generate this list is on github. Fixes welcome. See also my TypeScript cheat sheet, TypeScript React cheat sheet, and Docker cheat sheet.

  • There are separate sections for "private" or "magic" types with a $ in the name. See the note here and comment here. Update: Some these types are now documented here.
  • Links in bold point to the Flow documentation. Other links point to the Flow source code.
