redux-saga-effects v1.1.0

redux-saga-effects

Small package to help import effects from redux-saga package.

Installation

npm i redux-saga-effects

Motivation

You are using:

• Webpack 2 with Tree-Shaking or Rollup (your config is working with jsnext:main field)
• redux-saga (which is great btw!)

And you have code like this:

import {
  call,
} from 'redux-saga/effects';

function* someSaga() {
  yield call(anotherFunction, 'param1');
}

All is OK, except for... this is not working well with jsnext:main.

Details is here.

Much more details can be found in related issue https://github.com/redux-saga/redux-saga/issues/689.

Duplication of redux-saga adds ~30Kb to your bundle size (unminified, not compressed).

If you are not using Webpack 2 or Rollup or just don't care about your bundle size - all is fine, this package just not for you! 😉

But what to do if you need this to be working well and don't want to type more?.. 🤔

Possible solutions for proper work with jsnext:main:

1. Destructure effects later

import {
  effects, // <---- changed!
} from 'redux-saga';

const { // <---- added!
  call, // <---- added!
} = effects; // <---- added!

function* someSaga() {
  yield call(anotherFunction, 'param1');
}

In this case destructuring like that should take place in each file - it's OK, but need something better

2. Just use effects without destructuring

import {
  effects, // <--- changed
} from 'redux-saga/effects';

function* someSaga() {
  yield effects.call(anotherFunction, 'param1'); // <--- changed
}

If you OK with this style - it's good solution. But you need to type more. And read more, actually. But here is another option!

3. Use this package

import {
  call,
} from 'redux-saga-effects'; // <--- changed

function* someSaga() {
  yield call(anotherFunction, 'param1');
}

Look, just one symbol changed! 🔮

Benefits you get using this package:

• convinient API - all docs is coming from redux-saga itself, no additional wrappers, just re-export
• easy to migrate with existing codebase
• reduce bundle size for free - package is just 20 lines of code. Compare this with ~30Kb from duplication of redux-saga... 🤓

Downsides: install "one more package"
