Misk Simple Redux

Using Redux can be simple.

@misk/SimpleRedux includes all the Redux parts necessary for forms, network requests, and other interactive components. Don't write Redux boilerplate for basic interactivity again.

Getting Started

$ npm install @misk/simpleredux

SimpleSelector

simpleSelectorGet

Allows for single-key cached selection from Redux state

Most directly equivalent to deprecated simpleSelect

// OLD
const field1 = simpleSelect(props.simpleForm, "Dino::Field1", "data")
const tagsField = simpleSelect(props.simpleForm, "Dino::Tags", "data", simpleType.array)

// NEW
const field1 = simpleSelectorGet(props.simpleForm, ["Dino::Field1", "data"])
const tagsField = simpleSelectorGet(props.simpleForm, ["Dino::Tags", "data"], [])

simpleSelectorGet
- subState: same as parameter 1 for simpleSelect. Example: props.simpleForm, props.simpleNetwork
- path: allows any length path to an object key you'd like to access. This combines parameter 2 and 3 of simpleSelect.
  - Examples: "Dino::Name.data", ["Dino::Price", "data"]
  - Same as parameter in Lodash/Get
- defaultValue? is optional and allows setting of a default value if the requested path is not found.
  - Examples: false, [], {}
  - This is useful for cases like storing a list of tags where the UI expects an empty array [] in the case of no elements, not undefined.
  - Same as parameter in Lodash/Get

simpleSelectorPick

Allows for multi-key cached selection from Redux state

// OLD
const fields = [
  "Name",
  "Price",
  "Itemized Receipt",
  "CheckAlice",
  "CheckBob",
  "CheckEve",
  "CheckMallory",
  "CheckTrent",
  "Meal",
  "Tags"
].map((f: string) => `Dino::${f}`)
const fieldsData = fields
  .map((key: string) => {
    const value = simpleSelect(props.simpleForm, key, "data")
    return { [key]: value }
  })
  .reduce((prev, current) => ({...prev, ...current}), {})

// New
const fields = [
  "Name",
  "Price",
  "Itemized Receipt",
  "CheckAlice",
  "CheckBob",
  "CheckEve",
  "CheckMallory",
  "CheckTrent",
  "Meal",
  "Tags"
].map((f: string) => `Dino::${f}.data`)
const fieldsData = simpleSelectorPick(props.simpleForm, fields)

simpleSelectorPick
- subState: same as parameter 1 for simpleSelect.
  - Example: props.simpleForm, props.simpleNetwork
- paths: array of paths of keys to return from object.
  - Example: ["Dino::Name.data", "Dino::Price.data"]
  - Same as parameter in Lodash/Pick

Merge and Failure Sagas

Dispatched actions can include an options object that has two very powerful keys:

mergeSaga
failureSaga

These are Redux sagas that are run on merge (success) or failure and allow for an additional async block of computation that include other network calls, seeding to many fields parts of the network response data, and anything else.

Both mergeSaga and failureSaga follow the same generic Redux Saga API. Consider looking at the src/saga.ts or src/utilities/mergeSaga.ts code to find examples of sagas already part of @misk/simpleredux.
