Choosing a JavaScript framework is often the subject of heated debates between developers. In practice, there are several good choices for most projects, and what really makes the difference is the questions you ask before deciding. Here are the ones I always ask, and what each answer implies.
The usual candidates
- React: an interface library, the most widespread, with a huge ecosystem; you complete it with the tools of your choice (routing, state management), or with Next.js.
- Angular: a complete, structured framework maintained by Google, with everything included (routing, forms, HTTP requests) and TypeScript required.
- Vue: a progressive framework, known for being easy to pick up, with Nuxt for server-side rendering.
- Svelte: a different approach, which compiles components into lightweight JavaScript; a smaller but active community.
Who will maintain the project afterwards?
This is often the most important question. A very widespread framework such as React makes it easier to hire a replacement developer or a subcontracting agency. A more niche choice can be technically excellent, but complicates things if the original developer is no longer available. If your team already knows one of them, that is a strong argument in its favor.
What is the real size and complexity of the project?
Angular enforces a complete structure, designed for large enterprise applications with several teams: that structure becomes an asset when many developers work on the same code. For a simpler interface, it becomes a cost with no real benefit: React or Vue, lighter and more flexible, are more than enough.
Does the project need to rank in search engines?
If the site must appear in search results, the choice of framework must come with a server-side rendering solution: Next.js for React, Nuxt for Vue, Angular SSR for Angular, SvelteKit for Svelte. Google can run JavaScript, but content generated only in the browser is indexed later and less reliably. The details are in Next.js or plain React: when server-side rendering changes everything.
TypeScript: yes, almost always
Whatever the framework, writing code in TypeScript rather than plain JavaScript catches many errors before the code even runs, and makes it easier to take over. Angular requires it; with React, Vue or Svelte, it is a choice to make from the start, because adding it later costs more.
Ecosystem and lifespan
An actively maintained framework, with up-to-date documentation and an active community, reduces the time spent looking for solutions to problems others have already solved. Also look at the release policy: Angular publishes a support schedule for each major version, which helps plan upgrades; React evolves more freely but with strong compatibility. In any case, plan time for major upgrades every one to two years.
Questions to ask
| Question | If the answer is… | Then… |
|---|---|---|
| Who will maintain the project? | A provider to be found later | Favor the most widespread (React) |
| How many developers? | Several teams, a large application | Angular becomes attractive |
| Must it be found on Google? | Yes | Plan server-side rendering (Next.js, Nuxt…) |
| Must the project last? | Several years | TypeScript, solid ecosystem, planned upgrades |
| Is the deadline short? | Yes | The framework the team already knows |
In short
The right framework is rarely the one with the most advantages on paper. It is the one that fits the size of the project, the team that will maintain it and the real constraints: SEO, deadlines, budget.
