action-processor

Simple utility to run a series of functions over an initial state and return the end state.

Supports async functions which will be waited upon before the next action, to ensure actions are completed sequentially.

Supports ignoring failed actions .

Installation

npm i -S action-processor

Usage

action-processor exposes a simple API:

const {run} = require('action-processor');

const result = run(initialState, actions, opts);

Where:

• initialState is any value. It will be passed as the only argument to the first item in actions.
• actions is an array of functions or async functions (or a mixture). Each function should take one argument: previousState and return the next state to pass to the next action function (or be returned in the case of the last action).
• opts is an object with the following settings:
  • continueOnFailure (default: false): If set to true, any action invocation which throws an error will be skipped, and the chain will continue as if that action were not included.
