What this file does

Benchmarks React-Redux performance across versions, with configurable run length and selective benchmark execution.

When to use it

  • Compare React-Redux versions for performance regressions
  • Measure app performance under specific benchmark scenarios
  • Automate performance testing in CI pipelines
  • Add custom benchmarks to track regressions over time

Assumes this stack

react-redux-benchmarks

Performance benchmark harness for React-Redux

This repo expects that you are using Yarn for package management.

Running benchmarks

yarn initialize
yarn start

After benchmarks have been initialized, you can run with simply:

yarn start

Running specific versions

To specify a single version:

REDUX=5.0.7 yarn start

To specify running against multiple versions:

REDUX=5.0.7:4.4.9 yarn start

To run a specific benchmark:

BENCHMARKS=stockticker yarn start

or specific benchmarks:

BENCHMARKS=stockticker:another yarn start

Setting run length

By default, benchmarks run for 30 seconds. To change this, use

SECONDS=10 yarn start

Adding a benchmark

Benchmarks live in the sources/ directory. Each benchmark must insert this code into index.js:

import 'fps-emit'

In addition, a config-overrides.js must be created with these contents:

module.exports = function override(config, env) {
    //do stuff with the webpack config...
    console.log(`Environment: ${env}`)

    if(env === "production") {
        config.externals = {
            "react" : "React",
            "redux" : "Redux",
            "react-redux" : "ReactRedux",
        }
    }


    return config;
}

and the scripts section of package.json should be changed to:

  "scripts": {
    "start": "react-app-rewired  start",
    "build": "react-app-rewired  build",
    "test": "react-app-rewired  --env=jsdom",
    ...
  }

Also, index.html must be modified to include these lines:

    <script type="text/javascript" src="redux.min.js"></script>
    <script type="text/javascript" src="react.production.min.js"></script>
    <script type="text/javascript" src="react-dom.production.min.js"></script>
    <script type="text/javascript" src="react-redux.min.js"></script>

If you need to make changes to the fps-emit package, bump the version number in its package.json, then update each benchmark to use the newest version using yarn upgrade-interactive and selecting fps-emit for an update. Then rebuild all the benchmarks using yarn initialize

What's inside

5 sections covering setup, running, version selection, benchmark addition, and fps-emit updates, with 4 code blocks and 2 command examples.

Change this for your project

  • Replace REDUX=5.0.7 with your target Redux versions
  • Replace BENCHMARKS=stockticker with your benchmark names
  • Replace sources/ directory path if your benchmarks live elsewhere

Where it goes

Keep alongside your test suite. Used to define and score model evaluations.
