Warn about slow reducers in your [Redux](https://redux.js.org/) app.

Fork of [redux-log-slow-reducers](https://github.com/michaelcontento/redux-log-slow-reducers)

## Installation

```shell
npm install --save redux-log-slow-reducers
# or
yarn add @martini97/redux-log-slow-reducers
```

## Usage

```js

// Note: There is a optional second argument to logSlowReducers which allows you
//       to define how slow a reducer must be to trigger a warning (in ms) and
//       a predicate to decide whether or not to wrap the reducer functions. The
//       default value for threshold is 8ms, as this is half the time available
//       in one frame to run at 60fps. If you do not pass a predicate it will
//       always wrap the reducers.

import logSlowReducers from '@martini97/redux-log-slow-reducers';
import { createStore, combineReducers } from 'redux';

import * as reducers from './reducers';

const loggingReducers = logSlowReducers(
  reducers,
  { thresholdInMs: 10, predicate: () => process.env.NODE_ENV !== 'production' }
);
const store = createStore(combineReducers(loggingReducers));
```

## Contributing

This project uses [commitlint](https://commitlint.js.org/#/) to enforce commit
patterns, since it runs on CI there is no getting around that, so if you want to
avoid having your CI breaking, consider adding this to your `.git/hooks/commit-msg`:

```bash
ROOT=$(git rev-parse --show-toplevel)
NODE_BIN="$ROOT/node_modules/.bin"
COMMITLINT="$NODE_BIN/commitlint"

sed '/^# Please enter the commit message for your changes/,$d' $1 | $COMMITLINT
```
