JavaScript architecture since 2012
Choose an architecture, not a trend
React, Angular and Vue meet different needs. The right choice depends less on a general classification than on the product to be built, its rendering method, the skills of the teams and its lifespan.
PartITech supports JavaScript projects from framing to operation. We first assess whether a framework is actually necessary, then we choose the ecosystem and architecture that reduces the overall project risk.
- Need before tool
- A decision related to uses
- Controlled rendering
- SPA, SSR, static or hybrid
- Full cost
- Construction, operation and evolution
Useful complexity
When a JavaScript framework provides value
A framework becomes relevant when it structures real complexity. For a primarily editorial page, the web platform and a few targeted components are often more effective.
Many states
The interface combines remote data, filters, forms, permissions, errors, loading and frequent updates.
Shared components
Several paths reuse complex behaviors which must remain consistent and testable.
Sustainable product
A team must evolve the application over several years with explicit agreements and responsibilities.
Rich interactions
Editors, dashboards, configurators or business tools go beyond the one-off interactions of a content site.
Distributed team
A common architecture facilitates the division of work, reviews and transmission between developers.
Industrialized tests
Components, services and application flows must be able to be isolated, simulated and validated automatically.
Library, framework, ecosystem
React, Angular or Vue?
React presents itself as an interface library. Angular is a complete web framework. Vue is a progressive framework. This difference in scope directly influences the decisions that a team must make itself.
The decisive criterion
The system around the interface
Routing, data, server rendering, authentication, forms, testing, observability and deployment matter as much as component syntax.
Discover our front-end approach- What content should be available without JavaScript?
- How much of the application requires rich interactivity?
- Is server rendering necessary for SEO or speed?
- What skills can the team maintain sustainably?
- Who provides updates to the ecosystem and dependencies?
React
Composable ecosystem
Library focused on interfaces. A complete application typically relies on a React framework for routing, data, and rendering.
Angular
Integrated framework
Complete framework with components, dependency injection, routing, forms and consistent tooling for large teams.
Vue
Gradual adoption
Framework component that can enrich an existing page or structure an application with its official ecosystem.
Web platform
Without application framework
HTML, CSS, JavaScript modules and Web Components can be sufficient when interactivity remains localized and maintenance simple.
There is no best universal framework
A proof of concept limited to the riskiest component is often more informative than an abstract comparison. It makes it possible to measure rendering, weight, developer experience and integration with the existing system.
The rendering is a product choice
SPA, SSR, static generation or hybrid approach
The framework alone does not determine quality. Work sharing between server and browser influences SEO, speed, hosting and resiliency.
Single page application
Adapted to very interactive tools, but demanding on initial loading, transition accessibility and network error management.
Server-side rendering
Produces HTML on request, useful for dynamic content and SEO, at the cost of an infrastructure and a cache to control.
Static generation
Offers simplicity and speed for content reconstructed upon publication, with a necessary strategy for frequently updated data.
Selective hydration
Adds interactivity only to areas that need it to reduce JavaScript sent to the browser.
Backend for Frontend
Adapts several services to the precise needs of the interface and centralizes certain authentication and aggregation concerns.
CMS integration
Trimming should preserve preview, post, editorial components, redirects, and metadata.
A lasting decision
Evaluate the full cost of the ecosystem
Initial development time is only part of the cost
We look at updates, skills availability, migration tools, dependency stability, rendering, hosting, and the ability to diagnose an incident in production.
The level of standardization must remain proportionate to the product. A very flexible architecture can multiply decisions, while a very integrated framework can impose unnecessary conventions.
- Functional complexity and lifespan
- Skills and organization of the team
- SEO, accessibility and performance
- Rendering, caching and infrastructure
- Versions and security policy
- Tests, observability and reversibility
The official documentation specifies their positioning: React, Angular and Vue.
A demonstrable decision
Our method for choosing and framing the framework
The final recommendation links product constraints to explicit and testable criteria.
Mapping routes
Content, interactions, data, roles, devices, frequency of use and degraded scenarios.
Measuring complexity
Shared states, real time, forms, navigation, rights and component reuse needs.
Set rendering
SEO, first consultation, personalization, cache and distribution between server and browser.
Evaluate the existing
Backend, CMS, APIs, hosting, security, CI/CD and skills available.
Compare options
Matrix weighted on the project criteria, including the absence of an application framework.
Prototype the risk
Implementation of the most uncertain path or component with realistic data.
Validate the qualities
Performance, accessibility, testability, developer experience, security and usability.
Formalize the decision
Architecture, conventions, responsibilities, update schedule and re-evaluation conditions.

PartITech Expertise
A recommendation adapted to your organization
We build and rewrite JavaScript applications with React, Angular, Vue and web standards. This diversity allows us to advise a project without imposing a single solution.
Our goal is an architecture that your teams can understand, exploit and evolve sustainably.
