Valkit is a lightweight utility library designed to simplify value processing.

Supports React(16+), Vue(3+), and TypeScript.

Examples

In Vue Template's for loop, it's often necessary to process some values of item, for example:

<template>
 <div v-for="item in items" :key="item.id">
 <img v-if="item.cover || item.image" :src="item.cover || item.image" />
 <div>{{ item.name }}</div>
 </div>
</template>

Valkit helps reuse value-processing code:

<template>
 <div v-for="item in items" :key="item.id">
 <Valkit :value="item" :resolver="(item) => item.cover || item.image">
 <template #default="{ value: cover }">
 <img v-if="cover" :src="cover" />
 <div>{{ item.name }}</div>
 </template>
 </Valkit>
 </div>
</template>

Usage

Core

  • valkit(value, resolver)
  • valkitResolve(value, resolver)
  • valkitIs(value, predicate)
  • valkitSafe(value, fallback)
import { valkit, valkitResolve, valkitIs, valkitSafe } from 'valkit'
valkit(1, (v) => v) // 1
valkit(
 () => 1,
 (v) => v
) // 1
valkitIs(1, (v) => v === 1) // true
valkitSafe(1) // 1
valkitSafe(() => {
 throw new Error('test')
}, 1) // 1

React

  • Valkit
  • ValkitResolve
import { Valkit } from 'valkit/react'
const Component = () => <Valkit value={1} resolver={(v) => v} render={(v) => <div>{v}</div>} />

Vue

  • Valkit
  • ValkitResolve
<script setup>
 import { Valkit } from 'valkit/vue'
</script>
<template>
 <Valkit :value="1" :resolver="(v) => v">
 <template #default="{ value }">
 <div>{{ value }}</div>
 </template>
 </Valkit>
</template>
