Package Exports

multi-condition
multi-condition/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (multi-condition) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Getting started

To install package from npm registry run:

npm install multi-condition

How it works?

A component that replaces and extends use of ternary operator in JSX.

Substitute `A ? B : C`

For example this:

{condition ? <ConditionTrue /> : <ConditionFalse />}

Can be replaced with:

import { Show, If, Else } from 'multi-condition';

<Show>
  <If condition={condition}>
    <ConditionTrue />
  </If>
  <Else>
    <ConditionFalse />
  </Else>
</Show>

Or this:

{condition ? <ConditionTrue /> : null}

Can be replaced with just:

<Show>
  <If condition={true}>
    <ConditionTrue />
  </If>
</Show>

Or this:

{firstCondition
  ? (
    secondCondition
      ? <FirstConditionTrueSecondFalse />
      : <FirstConditionTrueSecondFalse />
  ) : (
    <FirstConditionFalse />
  )
}

Can be replaced with:

<Show>
  <If condition={firstCondition}>
    <Show>
      <If condition={secondCondition}>
        <FirstConditionTrueSecondTrue />
      </If>
      <Else>
        <FirstConditionTrueSecondFalse />
      </Else>
    </Show>
  </If>
  <Else>
    <FirstConditionFalse />
  </Else>

Or this (same thing, less nesting):

<Show>
  <If condition={firstCondition && SecondCondition}>
    <FirstConditionTrueSecondTrue />
  </If>
  <If condition={firstCondition && !SecondCondition}>
    <FirstConditionTrueSecondFalse />
  </If>
  <Else>
    <FirstConditionFalse />
  </Else>
</Show>

Extend `A ? B : C`

Additionally, this component presents new option to show more than one branch at the same time:

<Show>
  <If condition={firstCondition}>
    <FirstConditionTrue />
  </If>
  <If condition={secondCondition}>
    <SecondConditionTrue />
  </If>
  <Else>
    <BothFalse />
  </Else>
</Show>

If both conditions are true, both FirstConditionTrue and SecondConditionTrue will be shown.
If one of them is true, then one component will be shown.
If both conditions are false, then BothFalse will be shown.

Different syntax

Of course if you prefer you can also import If, Else and Show components together:

import * as Show from 'multi-condition';

<Show.Show>
  <Show.If condition={true}>
    <ConditionTrue />
  </Show.If>
  <Show.Else>
    <ConditionFalse />
  </Show.Else>
</Show.Show>

Developing

You can freely clone this repository, create feature branch (e.g. feature/some-name) and run:

npm install

Make some changes that fit you and test it with:

npm run build
npm link

And in another local project where you want to use the package run:

npm link multi-condition

If everything works you can create pull request targeted to develop with your suggested changes.
