flow-setup

Always confused with all the config settings you need to have flow setup for a new project?

flow-setup is a simple no-install tool that will install flow on your project plus create all necessary config files.

A .flowconfig in particular will be created for you based on your needs. Great for when you're managing multiple projects you want to keep up to date. This can be configured to pull config files anywhere on github but by default comes from https://github.com/Brianzchen/flow-setup/tree/master/configs

Usage

1npx flow-setup [configName] [...options]
2# eg
3npx flow-setup
4npx flow-setup library
5npx flow-setup foo --owner=bar --repo=blah

By default this tool pulls configs from this repo but if you want to have something custom and don't want to contribute, you can create your own public repo without forking this tool with the Options guide below.

API

configName (Optional)

This is the name of the json file inside your config dir path that will be pulled, by default it will be looking for the file recommended.json if you don't specify anything.

Options

• owner: (default: brianzchen) The github owner for url pathing
• repo: (default: flow-setup) The github repo for url pathing
• path: (default: configs) The directory of the configs in the repo

You do not need to reference the branch as flow-setup reads from the default branch

Creating configs

Configs are just json files with properties that represent the various sections in a .flowconfig. Each property holds an array of strings for each row in a section.

Although some sections support key-value pairs, using strings allow for more universal compatibility for row values.

The config also supports a special extends property that takes a string, this will match to another config that your current config will merge with. Multiple configs can be merged recursively as one extends another.

Sample

1{
2  "extends": "base",
3  "ignore": [
4    ".*node_modules/.*",
5    "!.*node_modules/react-native/.*",
6    ".*node_modules/react-native/Libraries/polyfills/.*",
7    "!.*node_modules/@.*",
8    "!.*node_modules/date-fns/.*",
9    "!.*node_modules/tiny-invariant/.*",
10    "!.*node_modules/key-commander/.*",
11    "!.*node_modules/react-ld/.*"
12  ],
13  "lints": [
14    "deprecated-type=error",
15    "deprecated-utility=error",
16    "unnecessary-optional-chain=error"
17  ],
18  "options": [
19    "format.bracket_spacing=true",
20    "format.single_quotes=true",
21    "exact_by_default=true",
22    "include_warnings=true"
