Solidjs style utility components in React that is just 287 bytes!

---

What is this?

• 287 bytes
• Automatic type inference
• Can be imported in cjs or esm
• Full test-coverage

It is a super lightweight (287 bytes) only uility components to make your codebase shine ✨. Pretty much like solidjs style components such as For, Loop, Switch Switch.Case and If.

Why?

Here some codes to explore by yourself:

1. <For />

import { For } from 'react-utilify';

function Todos() {
  const todos = [
    { title: 'TS', name: 'For' },
    { title: 'Jest + RTL', name: 'map' },
  ];

  return (
    <>
      <For each={todos}>
        {(todo, idx) => (
          <>
            <p>
              {idx}: {todo.name}
            </p>
          </>
        )}
      </For>
    </>
  );
}

JS way:

import React from 'react';

function Todos() {
  const todos = [
    { title: 'TS', name: 'For' },
    { title: 'Jest + RTL', name: 'map' },
  ];

  return (
    <>
      {todos.map((todo) => {
        return (
          <>
            <h1>{todo.title}</h1>
            <p>
              {idx}: {todo.name}
            </p>
          </>
        );
      })}
    </>
  );
}

2. <If />

import { If } from 'react-utilify';

function Todos() {
  return (
    <>
      <if is={loading}>Loading...</if>

      <If is={error}>Error!</If>

      <If is={emptyData}>+Create task</If>

      <If is={data}>...</If>
    </>
  );
}

import React from 'react';

function Todos() {
  return (
    <>
      {isloading ? <>Loading...</> : <>''</>}

      {isError && !isLoading && <>Error!</>}

      {data.length === 0 && !isError && <>+Create task</>}

      {data.length > 0 && !isError && <>...</>}
    </>
  );
}

3. Switch -> Switch.Case

As opposed to If Switch Switch.Case renders only the case when is true and stops there!

function Todos() {
  const { loading, error, data } = useAPI(`todos`);

  return (
    <Switch>
      <Switch.Case is={loading}>Loading...</Switch.Case>

      <Switch.Case is={error}>Error!</Switch.Case>

      <Switch.Case is={data}>...</Switch.Case>
    </Switch>
  );
}

4. <Loop />

The use case of this componet is while layouting components and to see multiple components in action we need to copy paste same thing over and over. With this you will do your work much simpler and productively!

import { Loop } from 'react-utilify';

function Todos() {
  return (
    <Loop times={5}>
      <article>
        <h1>Some title</h1>
        <p>Some Paragraph</p>
      </article>
    </Loop>
  );
}
