@iyio/any-comp-cli v0.5.16

AnyComp

A lightweight replacement for Storybook designed to run directly in any React application.

Features

• Simplified Integration - No complex configuration or build steps. Just run the any-comp CLI and quickly test any of your components.

• Auto Scanning - All components in your project are automatically registered. No need to define a story for every component you want to test.

• Persistent Component State - Save and reload the state of your components as you test to quickly recreate specific testing conditions.

The CLI

When running, the watch-any-comp command scans and watches for changes to all of your components and generates a AcCompRegistry. This component registry can then be rendered by the AnyCompBrowser component which renders an interface similar to StoryBook and contains a searchable list of all the components in your project

The example below continuously watches the src/components directly and creates a component registry located at src/testing/all-comps.tsx. The component registry is updated with any changes while the watch-any-comp command is running.

npx watch-any-comp --dir src/components --outDir src/testing

Component Browser

Once your component registry has be created using the watch-any-comp command you can view your components using the AnyCompBrowser component. When using AnyComp with a NexJS project create a new page that renders the AnyCompBrowser component then browse to the newly created page.

NextJs Page example

import { AcCompRegistry, AnyCompBrowser } from '@iyio/any-comp';
import { useEffect, useState } from 'react';

export default function AnyCompExamplePage(){

    const [compReg,setCompReg]=useState<AcCompRegistry|null>(null);

    useEffect(()=>{
        // import dynamically to avoid NextJS server side errors
        import('../testing/all-comps').then(v=>{
            setCompReg(v.anyCompReg as any);
        })
    },[]);

    return (
        <div>
            {compReg && <AnyCompBrowser reg={compReg} rememberCompId/>}
        </div>
    );
};

Installation

AnyComp consists of 2 packages @iyio/any-comp and @iyio/any-comp-cli. @iyio/any-comp contains the AnyCompBrowser component and other supporting code used to render your component for testing. @iyio/any-comp-cli contains the watch-all-comps command used to build component registries.

npm install @iyio/any-comp
npm install @iyio/any-comp-cli --save-dev

Prop Bindings

Prop bindings allow you to connect value props to onChange callbacks. For example if you have a TextInput component with a value prop and an onChange callback called when the value changes you can have these 2 props automatically bound together. With StoryBook you would have to create a custom Template to bind the 2 values together.

By default AnyComp will automatically bind value to onChange and {x} to on{x}Change. You can also use tags defined in JSDoc style comments to define custom bindings that don't fit the auto binding naming convention.

Binding examples:

interface ExampleCompProps
{
    onChange:(value:string)=>void;
    value:string;

    age:number;
    onAgeChange:(value:number)=>void;

    jobTitle:string;
    /**
     * @acBind jobTitle
     */
    onPositionChange:(value:string)=>void;
}

Resulting bindings

onChange -> value
onAgeChange -> value
onPositionChange -> jobTitle

Tags

Tags allow you to customize the behaviour of your components when rendered by AnyComp. Tags are stored as metadata in JSDoc style comments.

• @acIgnore - Ignores the component or prop the tag is applied to.
• @acBind targetPropName - Binds a the callback prop to target prop.

Tag examples:

interface ExampleCompProps
{
    sirName:string;
    /**
     * @acBind sirName
     */
    onLastNameChange:(value:string)=>void;

    /**
     * @acIgnore
     */
    secretKey:string;
}

export function ExampleComp({
    sirName,
    onLastNameChange,
    secretKey
}:ExampleCompProps){

    // ...
}


/**
 * @acIgnore
 */
export function UtilityComp()
{

}
