Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Testing

This package logs the rendering of components in console by debug and highlights the extra renderings.

Installation

npm i @manauser/react-render-log

or

yarn add @manauser/react-render-log

or

pnpm add @manauser/react-render-log

Usage

app.tsx (variant 1 - with provider as a wrapper):

// app.tsx
import { FC } from 'react'
import { RenderLogProvider } from '@manauser/react-render-log'

import { Home } from './home'

const App: FC = () => (
  <RenderLogProvider
    debugEnabled={import.meta.env.MODE !== 'production'}
    isStrictMode={import.meta.env.MODE === 'development'}
  >
    <Home />
  </RenderLogProvider>
)

export default App

or app.tsx (variant 2 - with provider as a HOC withRenderLogProvider):

// app.tsx
import { FC } from 'react'
import {
  OwnRenderLogProviderProps,
  withRenderLogProvider,
} from '@manauser/react-render-log'

import { Home } from './home'

const App: FC = () => <Home />

export default withRenderLogProvider.apply(
  {
    debugEnabled: import.meta.env.MODE !== 'production',
    isStrictMode: import.meta.env.MODE === 'development',
  } satisfies OwnRenderLogProviderProps,
  [App],
)

or app.tsx (variant 3 - with combine providers via combine-function):

// app.tsx
import { FC } from 'react'

import { Home } from './home'
import { withProviders } from './providers'

const App: FC = () => <Home />

export default withProviders(App)

where withProviders is a function that wraps the component in all the providers you need.
You need to install for this case compose-function package.

// providers.ts
import { withRenderLogProvider } from '@manauser/react-render-log'
import compose from 'compose-function'

export const withProviders = compose(
  withRenderLogProvider.bind({
    debugEnabled: import.meta.env.MODE !== 'production',
    isStrictMode: import.meta.env.MODE === 'development',
  }),
)

home.tsx (as example of using withRenderLog HOC):

// home.tsx
import { FC } from 'react'
import { withRenderLog } from '@manauser/react-render-log'

import { Smt } from './smt'

const Home: FC = () => (
  <div>
    <Smt renderLogId="1" title="first" />
    <Smt renderLogId="2" title="second" />
  </div>
)

export default withRenderLog(Home) // or withRenderLog(Home, 'SomeCustomName')

By render list of the same components (like above), you should use renderLogId prop (like a key). In this case, the props of this component should be wrapped in PropsWithRenderLog type.

smt.tsx (as example of using withRenderLog HOC and PropsWithRenderLog):

// smt.tsx
import { FC } from 'react'
import { PropsWithRenderLog, withRenderLog } from '@manauser/react-render-log'

type Props = {
  title: string
}

const Smt: FC<PropsWithRenderLog<Props>> = ({ title }) => <div>{title}</div>

export default withRenderLog(Smt)
