Revision: revised around component conventions, state ownership and a proposed customer-directory evaluation.
Compare React and Vue by implementing the same behavior and reviewing how the result will be maintained. Their component and state conventions differ, but neither name determines whether a form handles errors correctly or an application fits your existing backend. For the broader shortlist, see our Angular, React and Vue comparison.
This guide goes deeper into one fictional customer directory. A user filters customers using the URL query parameter q, opens a customer, edits a form and saves or cancels. The evaluation below is proposed work, not a report of executed React and Vue implementations or measured performance.
Compare the component conventions
A typical React component describes its interface with JSX and handles edits through events and state updates. For an object held in component state, React recommends treating the existing value as read-only: produce the next value and pass it through the state setter. The directory's saved customer and its editable draft should have distinct responsibilities.
Vue single-file components commonly combine a template, logic and styles. With <script setup>, declared state and functions are available to the template. Vue's reactivity guide describes ref() values and reactive() objects: tracked reads and changes allow Vue to update dependent rendering. Updating a reactive draft is a different convention from replacing a React state object.
That difference affects code review, not the product requirement. In both versions, cancelling an edit must leave the accepted customer record unchanged. Avoid using the same mutable object as both the saved record and the draft merely because it is convenient to pass around.
Give each piece of state an owner
React's shared-state guidance describes moving coordinated state to a common parent and passing values and event handlers to children. Vue's props guidance likewise describes downward data flow and recommends child events when the parent should change its state. Vue's component v-model offers a convenient update convention; it does not remove the need to decide who owns a value.
For this directory, keep the applied filter in the URL and define how a draft search input becomes that filter. Keep the selected customer identifier separate from the customer's editable fields. Decide whether an unsaved edit survives navigation or requires a discard decision. These choices belong to the application, regardless of the binding syntax.
| Event or state | Ownership decision | Evidence to request |
|---|---|---|
| Filter changes | The applied query is represented by URL q; input and navigation follow a defined update policy. | Reload and browser Back restore the intended query and result set. |
| A list response arrives late | Only a response belonging to the current query may replace its displayed results. | A slower earlier request cannot overwrite a later filter result. |
| An edit is cancelled | The form owns a draft; accepted customer data changes only through the save workflow. | Discarding changes restores the original visible values without a save request. |
| The server rejects a save | The server owns authorization and validation; the form owns actionable error presentation. | Field errors remain associated with the correct draft, and entered values remain available. |
| Save is submitted again | The application defines repeated-request behavior and identifies which customer and revision the result belongs to. | No misleading double-success or stale response replacing another customer's form. |
Use a shared store or a data-fetching library when it solves an actual coordination problem. Document what it owns: URL state, cached server records and unsaved form input are not interchangeable. A small directory does not automatically require every value in a global store.
Make typed forms and API errors a shared contract
Agree a customer representation, editable fields, optional values and validation-error structure. If the project uses TypeScript, define those shapes explicitly and also check incoming data at runtime where required. Keep server validation and authorization in the acceptance criteria rather than treating frontend types as their substitute.
Specify loading, empty, failed-load, saving and failed-save states. An empty result is different from a failed request. Decide what a user can do after each failure, how unsaved values are preserved and when focus should move to an error. Check the same behavior using keyboard input and a narrow screen.
A disabled Save button can communicate a pending action, but repeated requests still need a defined server outcome. A response must be associated with the customer and operation it answers. These rules are more useful review criteria than counting how many lines one framework needs for the form.
Choose an embedded widget or a route-based application
If Laravel already renders the directory page, either technology can own an interactive region within it. React documents adoption inside existing pages, and Vue supports progressive enhancement as well as full applications. Using React does not require rewriting every route; Vue is not restricted to small widgets.
For an embedded directory, define the mounting boundary, initial data, API access and asset build. Keep another script from independently rewriting the same managed elements. For a fuller application, decide who owns routing, data loading, error handling and navigation between forms. The additional responsibilities come from the chosen architecture and tooling.
Our PHP frontend guide explains the relationship between server-generated HTML and browser interactivity. Start with the existing application's boundaries when assessing the cost of either integration.
Review server rendering and browser execution separately
Both ecosystems support server-rendered interfaces. Hydration connects client behavior to matching initial markup. React's hydration documentation requires the initial client output to match its server-rendered content. Vue's SSR guide discusses browser-only APIs, shared server state and hydration mismatches.
For the directory, establish where authenticated data is loaded and which execution environment can access each dependency. A browser-only editor must be used where browser APIs exist. Server-rendered content and working interactive controls are separate observations; assess both instead of assuming initial HTML establishes the complete experience.
Use a comparable trial to make the decision
Give both proposed implementations the same customer fixtures, API contract and acceptance tasks. Include a late response, cancelled edit, validation rejection and repeated submission. Ask a maintainer to explain the state ownership, make a small field change and update the related checks.
Record the required libraries, integration work, review difficulties and unresolved behavior in the frontend evaluation workbook. Any performance comparison needs stated builds, data, devices and measurements; component syntax and virtual DOM descriptions do not establish a universal winner.
