To have a home place where people can refer back for Flow problems
To have people collectively share knowledge about Flow
Current Flow material
This is an incomplete list of things done well around Flow. The intention is not to make judgement, but rather to serve as references to existing materials and as planner for missing pieces.
Flow docs has complete basic types and Algolia search
CodeSandboxes for more complex demos than Try Flow bookmarklets
Problem solving (Flow docs has an FAQ page but it's a single page collection of questions and answers without a table of content, so it is not very easy to browse around)
Flow practices / cookbook / how-to guides
Troubleshooting with tooling, IDE support, configuration with prettier and babel, etc.
