vue-json-compare

library3.0.0jsnpmunverified

vue-json-compare is a Vue 2.x component designed for visually comparing two JSON objects or arrays. It accepts `oldData` and `newData` props, highlighting structural and value differences in a side-by-side, hierarchical display. The current stable version, 3.0.0, was last published over 5 years ago and is exclusively compatible with Vue 2 applications. Given that Vue 2 officially reached its end-of-life on December 31, 2023, this package is effectively deprecated and unsupported for new projects. Its primary differentiator was providing an immediate UI solution for JSON diffing within Vue 2 ecosystems, contrasting with lower-level JavaScript diffing libraries by offering a complete visual component. The project appears to be abandoned, with no active development or known support for Vue 3.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

vueJsonCompare

✓ import vueJsonCompare from 'vue-json-compare';

✗ import { vueJsonCompare } from 'vue-json-compare';

The component is exported as a default export, not a named export. It must be registered globally or locally within a Vue component's `components` option.

vueJsonCompare

✓ Vue.component('vue-json-compare', vueJsonCompare);

✗ const vueJsonCompare = require('vue-json-compare');

For global registration in a Vue 2 application, `Vue.component` is used. CommonJS `require` syntax is typically not used directly for client-side Vue components.

VueJsonCompare

✓ import type VueJsonCompare from 'vue-json-compare';

✗ import { VueJsonCompare } from 'vue-json-compare';

For TypeScript users, type definitions are available via `@types/vue-json-compare`. The component is a default export, so type import should reflect that. The type package is also quite old.

This example demonstrates basic usage by importing and registering the `vue-json-compare` component, then passing two JSON objects, `oldData` and `newData`, as props to display their differences.

<template> <div> <vue-json-compare :oldData="oldData" :newData="newData"></vue-json-compare> </div> </template> <script> import vueJsonCompare from 'vue-json-compare'; export default { components: { vueJsonCompare }, data () { return { oldData: { id: 1, name: 'Alice', settings: { theme: 'dark', notifications: true }, tags: ['user', 'admin'] }, newData: { id: 1, name: 'Alicia', age: 30, settings: { theme: 'light', notifications: true }, tags: ['user', 'premium'] } }; } }; </script>

Debug

Known issues

breakingThis package is explicitly built for Vue 2.x and is not compatible with Vue 3. Attempting to use it in a Vue 3 project will result in runtime errors due to breaking API changes between Vue major versions.

fix

For Vue 3 projects, consider alternative JSON diffing libraries or components built specifically for Vue 3, such as `json-diff-kit-vue`.

affects: >=3.0.0

deprecatedThe project appears to be abandoned. The last npm publish was over 5 years ago, and the last commit on GitHub was 6 years ago. There is no active development, maintenance, or support for this component. Vue 2 itself reached End of Life on December 31, 2023.

fix

It is strongly recommended to use a more actively maintained library, especially for production environments, or consider migrating to a Vue 3 compatible solution.

affects: >=3.0.0

gotchaThe component does not expose any events, meaning there's no programmatic way to interact with user actions within the comparison UI or to get callbacks on changes, as stated in its README.

fix

If interactive behavior or event handling is required, custom wrappers or modifications to the component's source might be necessary, or an alternative library should be chosen.

affects: >=3.0.0

gotchaPerformance might degrade significantly when comparing very large or deeply nested JSON objects due to client-side DOM rendering and diffing calculations, potentially leading to UI freezes.

fix

For extremely large datasets, consider pre-processing and diffing data on the server-side, or using a virtualized list/tree component if available for similar libraries.

affects: >=3.0.0

Errors

Common errors & fixes

Failed to mount component: template or render function not defined.

The Vue component was not correctly imported or registered in the parent component or globally.

fix

Ensure `import vueJsonCompare from 'vue-json-compare';` is used and `vueJsonCompare` is included in the `components` option of your Vue component.

Cannot read properties of undefined (reading 'someProperty') in vue-json-compare component

The `oldData` or `newData` props were passed as `undefined` or `null`, or contained unexpected non-object/array values where the component expected them.

fix

Always ensure `oldData` and `newData` props are valid JavaScript objects or arrays, even if empty, e.g., `:oldData="oldData || {}"` or `:newData="newData || []"`.
