By the end, you’ll have a clear sense of the strengths and weaknesses of each framework to make an informed decision for your needs.
1. Origin and History
Angular
Angular is an open-source web application framework led by Google. The initial version, AngularJS, was released in 2010. AngularJS gained popularity quickly due to its innovative two-way data binding.
In 2016, Google released a complete rewrite of the framework called Angular (version 2 and above). This iteration focused on best practices and performance improvements.
Since then, Google has consistently maintained Angular and released updates in 6 month cycles. The latest version at the beginning of 2023 is Angular 15.
Vue.js
Vue.js was created by former Google employee Evan You in 2014. His motivation was to build a lightweight framework that kept the elements he liked from Angular while improving what he didn’t like.
The first public release came in 2015. Since then, Evan You has led its development along with other open source contributors. Vue has grown to become the second most popular JavaScript framework without major corporate backing.
The latest version is Vue 3, officially released in 2020. Vue 3 introduced breaking changes over Vue 2, with a re-written architecture for improved performance.
2. Philosophy and Approach
Angular
Angular firmly fits in the opinionated category of frameworks. It seeks to give developers a complete, batteries-included platform for building complex web applications.
Out of the box, Angular provides:
- A component-based architecture
- Powerful templating and data binding
- An integrated testing platform
- A full-featured CLI for project scaffolding
- Detailed documentation guiding best practices
This prescriptive approach lets teams hit the ground running. It also enforces consistency across large codebases.
Ultimately, Angular favours convention over configuration. The framework makes decisions on your behalf to ensure stability and ease of maintenance.
However, this does limit flexibility compared to less opinionated alternatives.
Vue.js
The core library of Vue.js is designed to be progressive and incrementally adoptable. The library focuses solely on the ‘view layer‘ – specifically an easy-to-use template syntax and reactive data binding.
With just this view layer, Vue provides enough declarative rendering capability for most applications. However, the framework doesn’t force any decisions on project structure, routers, state management, etc.
Instead, Vue promotes flexibility and user-choice. Additional libraries and architecture patterns integrate seamlessly with the reactive core of Vue as the application scales. These optional libraries include:
- Vue Router for SPA routing
- Vuex for complex state management
- Vue CLI for rapid scaffolding
This flexible approach allows tailored solutions on a per-project basis. You can start simple without complexity and then augment Vue incrementally. The downside is less structure for larger teams and applications.
3. Architecture
Both Angular and Vue adopt a component-based architecture. This allows building a complex UI from self-contained, reusable components that encapsulate their own logic and templating.
Angular components consist of:
- An ES6 class serving as the component controller
- An HTML template with Angular template syntax
- Component-specific styling
- Optional – additional metadata for dependency injection
Vue components also separate the same 3 concerns (HTML, CSS, JS) – but with slightly different implementations:
- The script section holds component logic
- The template section uses standard HTML with Vue directives
- Scoped CSS automatically applies to a component
Beyond components, Angular also enforces:
- Services for sharing data and functionality
- Dependency injection for increased modularity
- Strongly-typed templates and code with TypeScript
Vue relies more on developer discipline to separate concerns rather than framework constraints. That said, it does integrate nicely with TypeScript for developers who want static typing.
4. Learning Curve
Angular
Angular has a steep learning curve. Developing proficiency requires learning:
- TypeScript fundamentals
- Concepts like modules, components, services, dependency injection, etc
- Array of CLI commands
- Specific Angular template syntax
- Testing approach and tooling
With Google’s documentation and codelabs, mastering Angular is achievable. But the initial ramp up takes considerable time and effort in contrast to lighter-weight alternatives.
The benefit of this learning investment is standardized conventions and best practices for mid-large size teams. Stability and scalability also receive focus from the ground up.
Vue.js
One of Vue’s touted advantages is approachability for beginners. The core library focuses solely on providing an approachable template syntax and component model for binding HTML to JavaScript reactive data.
Proficiency in basic HTML, CSS, and JavaScript is enough to start building apps with Vue. Additional libraries and tools can be incrementally added later for more complex capabilities like state management, testing, etc.
That said, larger apps with Vue eventual require discipline around architecture patterns and best practices to keep things maintainable. The framework itself provides less guardrails here in contrast to Angular.
5. Documentation and Community Support
As popular open-source projects, both Angular and Vue have excellent documentation hubs and community support.
Angular
The Angular documentation stands as one of the framework’s strengths. It offers a structured learning path from beginner to advanced usage.
Beyond official documentation, Angular benefits from being a Google-backed project. The wider development community produces abundant educational content around the framework across blogs, courses, and videos.
Popular third party resources include:
- ng-conf – The official Angular conference
- Egghead.io – Video courses and tutorials
- Angular Weekly – Newsletter and podcasts
- /r/Angular2 – Reddit community
Vue.js
The Vue.js documentation also provides high quality learning resources covering all aspects of the framework.
As community-led project, Vue benefits from an engaged following of enthusiasts who generously share knowledge. Popular community channels include:
- Vue CONF – Vue’s official online conference
- Vue Mastery – Paid video courses by core team member
- Vue Newsletter – Weekly newsletter
- VueForums – Forum community
- /r/vuejs – Reddit community
6. Performance
Both Angular and Vue are designed for performance from the ground up – particularly around rendering efficiency.
Angular
Angular uses a range of performance optimizations:
- Change detection accurately updates only modified parts of the UI
- Ahead-of-time compilation (AoT) produces faster loading
- Lazy loading routes – only load JS required for each route
- Virtual scrolling displays large datasets efficiently
These optimizations provide excellent performance suitable for complex enterprise applications. Benchmark tests demonstrate comparable render times to lighter weight React.
That said, Vue generally edges out Angular in benchmarks – partially due to the latter’s added focus on stability guarantees.
Vue
Vue employs reactive, component-based architecture for optimal rendering speed and memory allocation.
Notably, Vue leverages a virtual DOM – a fast in-memory representation of the actual DOM structure. Using the virtual DOM, Vue can:
- Batch changes required before touching actual DOM
- Re-use DOM elements instead of recreate
- Intelligently re-order updates for optimization
For large lists, Vue also supports windowing techniques like virtual scrolling.
Independent benchmarks consistently rate Vue with industry-leading render performance, particularly with very large datasets. The tradeoff is slightly less out-of-box support for advanced capabilities like server-side rendering and statically-typed compilation.
7. Scalability
Scalability measures how well an app can grow in terms of features, users, team size, and data volumes.
Angular
Angular focuses heavily on scalability. The framework expects to power enterprise-level applications accessed by multitudes of users and complex data flows.
Several Angular features support growth:
Modularity – Apps structure into logically isolated NgModules making collaboration easier.
Hierarchy – Systemized organization of services, components, and dependencies.
Statically typed – TypeScript catches bugs during compilation that otherwise would manifest at runtime.
Automated testing – Framework supports test-driven development scalable to large engineering teams.
Server-side rendering – Angular Universal improves initial loads and SEO for public-facing sites.
Lazy loading – Only load JS modules required for each route chunking overall footprint.
Vue
Vue can certainly power performant, complex applications – but scaling requires more planning relative to Angular. The bare-bones Vue library itself has no imposed structure.
That said, Vue does offer official supporting libraries that introduce helpful architecture patterns:
- Vue Router enables routing and code splitting needed for large SPAs
- Vuex centralizes application state with redundancy for easier debugging
- Vue CLI generates starter scaffolding to ease project configuration
Additional dev tooling like TypeScript, Jest, and Cypress also integrate nicely for scaling needs but require more manual setup.
For large teams, Vue expects developers to align on architecture conventions and testing strategies – rather than receiving enforcements from the framework itself.
8. Ease of Integration
A major consideration is how easily the framework incorporates with other libraries and existing projects.
Angular
Integrating Angular requires alignment to its platform expectations:
- TypeScript usage
- Module imports
- Component, template, and service architecture
- Dependency injection configuration
Helper libraries ease integrating Angular with some popular tools like React (using ngReact) and Vue (with ngVue).
But in general, adding Angular entails adherence to Angular structure and best practices. This allows leveraging the full benefits but precludes quick injections into pre-existing projects.
Vue
A core design goal enables progressively enhancing existing projects with Vue.
At bare minimum, Vue requires only:
<script src="https://unpkg.com/vue"></script>Then works by adding v-directives to existing HTML templates.
This lightweight approach allows enhancing existing apps without disrupting current architectures or rewriting large code chunks. Vue also plays nicely with jQuery, integrating DOM manipulation in callback functions.
Additionally, specialty libraries enable running Vue alongside React (using Vue in React with Vue Activated) or Angular (using ngVue).
The compromise is lack of guidance around best practices when adopted only partially. For new projects, integrating Vue more wholly provides desired consistency and maintenance benefits.
9. Testing Capabilities
Automated testing improves quality assurance as applications grow in complexity. Both Angular and Vue integrate testing into their ecosystems.
Angular
Testing constitutes one core pillar of Angular’s entire philosophy. The framework itself includes an expansive testing platform with everything needed built-in.
Specifically Angular has:
- Karma – test runner that executes tests in real browsers
- Jasmine – testing framework to write specs in a BDD style
- Helper utilities like spies, fakes, mocks, etc
- End-to-end framework Protractor powered by Selenium
This robust testing story enables test-driven development at enterprise scales – with unit testing, integration testing, and e2e testing all available out-of-box.
Vue
The Vue ecosystem officially supports the testing utility Jest which offers browser environment mocking and assertions for unit tests.
For end-to-end testing, Vue provides integration with Cypress – a popular framework renown for ease-of-use.
Vue CLI also generates starter scaffolds with spec files and configuration pre-wired for both Jest and Cypress.
While Vue enables quality testing workflows, doing so requires more decisions around custom setup relative to Angular’s batteries-included approach. Testing benefits in Vue arrive after deliberately opting into features rather than receiving them built-in inherently.
10. Job Market Trend
Industries adopt technologies to solve problems. Job trends respondingly shift seeking skills where market demand localizes.
Both Angular and Vue represent mature, versatile frameworks employers leverage building complex web apps.
Angular
Built by Google, Angular reputation soared as a robust platform for data-driven enterprise use cases. Angular skills remain very relevant with steady job growth:
- 51,000+ jobs currently posted on Indeed.com
- YoY global job growth around 40% (2022 vs 2021)
Familiarity with TypeScript proves extremely valuable as well. TypeScript jobs grow quicker than overall JS jobs over the past 5 years.
Vue.js
Vue sits behind only React in popularity of front-end frameworks. Its approachable API and incremental style unlocked a more mainstream following.
Vue trends upwards in job availability but still trails the enterprise incumbency of Angular:
- 15,000+ Vue jobs on Indeed.com
- Global YoY growth around 20%
Acceptance continues rising across tech giants to startups alike. Vue Skills translate nicely to React roles as well given component architecture similarities.
Conclusion
Both Angular and Vue stand out as versatile, enterprise-ready frameworks for web development. Which better suits your needs depends on your app goals and team makeup.
Angular brings unrivaled cohesion – integrating robust capabilities for routing, state management, type safety, testing, and more all within one platform. Conventions and guidance set teams up for scale. All this power and structure does constrain flexibility however.
Vue delivers incremental value focused purely on an intuitive template syntax and reactive data binding model. Additional capabilities augment Vue as needed. Less structure grants teams freedom but sacrifices some built-in safeguards. Rapid prototyping soars but discipline still required when scaling up.
In summary:
- Angular shines keeping complex, data-driven sites stable and secure at scale
- Vue sprints where easy approachability, smooth integration, and high customization appeal
Both frameworks continue pushing JavaScript innovation for the modern web. For any significant application, you’ll productively satisfy requirements with either Angular or Vue.
