| 19 | + <h2 id="application-architecture">Application architecture</h2> |
| 20 | + <p> |
| 21 | + <strong>MPA (Multi-Page Application)</strong> and |
| 22 | + <strong>SPA (Single-Page Application)</strong> |
| 23 | + are the two foundational architectures for web applications. The choice between |
| 24 | + them shapes how pages are rendered, how navigation works, and how state is |
| 25 | + managed. In practice, many modern frameworks blur the line by supporting hybrid |
| 26 | + approaches — for example, combining server-rendered pages with client-side |
| 27 | + navigation. |
| 28 | + </p> |
| 29 | + <p>The key aspects that distinguish an application architecture are:</p> |
| 30 | + <ul> |
| 31 | + <li> |
| 32 | + <strong>Navigation model</strong> — Does the browser perform a full page |
| 33 | + load for each route (MPA), or does JavaScript intercept navigation and update |
| 34 | + the page in-place (SPA)? |
| 35 | + </li> |
| 36 | + <li> |
| 37 | + <strong>Content loading and processing</strong> — Is HTML assembled on the |
| 38 | + server and sent ready-to-display (MPA), or is it generated in the browser |
| 39 | + by a JavaScript framework consuming raw data fetched from an API (SPA)? |
| 40 | + </li> |
| 41 | + <li> |
| 42 | + <strong>State lifetime</strong> — Is in-memory state reset on every navigation |
| 43 | + (MPA), or does it persist across route changes within the same session (SPA)? |
| 44 | + </li> |
| 45 | + <li> |
| 46 | + <strong>JavaScript dependency</strong> — Is JavaScript required for the |
| 47 | + page to be meaningful, or is it an optional progressive enhancement on top |
| 48 | + of server-rendered HTML? |
| 49 | + </li> |
| 50 | + <li> |
| 51 | + <strong>SEO and initial load</strong> — Is content present in the first |
| 52 | + HTML response (MPA), or does meaningful content only appear after JS downloads |
| 53 | + and executes (SPA)? |
| 54 | + </li> |
| 55 | + </ul> |
| 56 | + |
| 57 | + <h3 id="mpa">Multi-Page Application (MPA)</h3> |
| 58 | + <p> |
| 59 | + In an MPA, each navigation triggers a full browser request and the |
| 60 | + server responds with a complete HTML document. HTML is generated on the |
| 61 | + server per request, so the browser always receives ready-to-display |
| 62 | + content. JavaScript is optional and typically used only for progressive |
| 63 | + enhancement. In-memory state is lost on every navigation. Because |
| 64 | + content is present in the initial HTML response, MPAs are naturally |
| 65 | + SEO-friendly. The server must be capable of rendering and serving a full |
| 66 | + page for every route. |
| 67 | + </p> |
| 68 | + |
| 69 | + <h3 id="spa">Single-Page Application (SPA)</h3> |
| 70 | + <p> |
| 71 | + In an SPA, the browser loads a single HTML shell once and all subsequent |
| 72 | + navigation is handled client-side by JavaScript, without full page |
| 73 | + reloads. HTML is generated in the browser, typically by a JavaScript |
| 74 | + framework rendering components on demand. On initial load the browser |
| 75 | + receives a minimal document and must download and execute JS before |
| 76 | + content appears. Subsequent navigations fetch only data (e.g. via API |
| 77 | + calls), keeping the page transition fast. In-memory state persists |
| 78 | + across navigation. Because the initial HTML shell contains little |
| 79 | + content, SPAs require extra effort (SSR, prerendering) for good SEO. The |
| 80 | + server only needs to serve static assets. |
| 81 | + </p> |
| 82 | + </section> |
| 83 | + |
| 84 | + <section> |
| 85 | + <h2 id="rendering-patterns">Rendering Patterns</h2> |
| 86 | + <p> |
| 87 | + A rendering pattern describes how and when content is generated and |
| 88 | + delivered to the client, typically the browser. The rendering process |
| 89 | + can happen on the client or on a server, and at different stages of the |
| 90 | + application lifecycle. |
| 91 | + </p> |
| 92 | + <p> |
| 93 | + Each pattern has different tradeoffs in terms of performance, SEO, UX, |
| 94 | + resource usage, robustness, and complexity. The choice of rendering |
| 95 | + pattern can have a significant impact on the overall experience and |
| 96 | + maintainability of the application. |
| 97 | + </p> |
| 98 | + |
| 99 | + <h3 id="ssg">Static Site Generation (SSG)</h3> |
| 100 | + <p> |
| 101 | + All pages are pre-built into static HTML files at build time (ahead of |
| 102 | + time) by a build tool or framework. The output is a set of |
| 103 | + ready-to-serve files — one per route — that can be delivered directly |
| 104 | + from a CDN with no server needed at runtime. Because every response is a |
| 105 | + pre-built file, load times are fast and infrastructure is simple. Best |
| 106 | + suited for content that doesn't change per request. |
| 107 | + </p> |
| 108 | + |
| 109 | + <h3 id="ssr">Server-Side Rendering (SSR)</h3> |
| 110 | + <p> |
| 111 | + HTML is generated on a server for each incoming request (just in time). |
| 112 | + This allows dynamic content and per-request logic such as |
| 113 | + authentication, personalization, or A/B testing. Unlike SSG, SSR |
| 114 | + requires a running server at runtime. |
| 115 | + </p> |
| 116 | + <p> |
| 117 | + The term SSR is often used together with |
| 118 | + <a href="#hydration">hydration</a>. However, classic SSR works without |
| 119 | + hydration — the server sends functional HTML that relies on native |
| 120 | + browser capabilities (links, forms) rather than a JavaScript framework. |
| 121 | + This is the traditional web model where JavaScript is only used for |
| 122 | + progressive enhancement, not for rendering core content. |
| 123 | + </p> |
| 124 | + |
| 125 | + <h3 id="csr">Client-Side Rendering (CSR)</h3> |
| 126 | + <p> |
| 127 | + Instead of receiving ready-made HTML from a server, the browser receives |
| 128 | + a minimal HTML skeleton and a JavaScript bundle. The JS framework then |
| 129 | + fetches data, builds the DOM, and controls all rendering on the client |
| 130 | + side. |
| 131 | + </p> |
| 132 | + <p> |
| 133 | + This enables highly dynamic interfaces where the page can update without |
| 134 | + full reloads. The tradeoff is a slower initial load — nothing meaningful |
| 135 | + appears until the JavaScript has downloaded and executed — and weaker |
| 136 | + SEO by default, since the initial HTML response contains little content. |
