Build a Portfolio Site

This guide builds a Portfolio site with a calm file-router map and expressive component-router motion: project modals, section tabs, theme toggles, and print/posture flags are all driven by route-visible state.

The defining pattern is theme by side effect: the route derives a theme token set in render and stores it (in a scope or a document) so every panel renders from a ready-to-use palette.

What You’re Building

Requirements

• Stable file routes for major sections: Home, Work, Writing, Contact.
• Component route motion for:
  • section tabs (Work: “Projects” vs “Speaking”),
  • a project modal overlay,
  • a “theme posture” switch (warm/ember/ink),
  • a print mode that changes layout without changing the file map.
• Stored derived “project snapshots” (preview strings, tag maps, visible ids).
• A contact form that keeps DOM truth and state truth alive together.

Non-requirements

• Perfect CMS integration.
• Perfect animation. This guide prefers visible re-render posture over intricate transitions.

Always-ready statement

Every section renders from stored derived structures:

• visibleProjectIds, projectSnapshotById, tagCounts, and heroLines.

Route Map (File Router) + Motion (Component Router)

File map (calm):

app/
  portfolio/
    page.tsx                 -> File route entry
    PortfolioShell.tsx       -> Global route contract + theme side effect
    data/
      usePortfolioContent.ts -> Render fetch content
    derive/
      deriveProjects.ts      -> Stored derived project snapshots
      deriveHero.ts          -> Stored derived hero lines
    sections/
      Home.tsx
      Work.tsx
      Writing.tsx
      Contact.tsx
    ui/
      PortfolioNav.tsx
      ProjectModal.tsx

Component motion (busy):

• Global route (useGlobalRoute("portfolio", ...)):
  • section (home | work | writing | contact)
  • theme (warm | ember | ink)
  • projectId (selected modal id or null)
  • print (on | off)
• Local route (useRouteState(...)):
  • Work tab: workTab (projects | speaking)
  • Writing tab: writingTab (posts | notes)

URL as hint:

• /portfolio/work?p=project-123 seeds projectId once; route truth controls overlays after render.

Step 1: Create a Route Shell (Global Contract + Theme Side Effects)

The shell is where you keep the route contract readable and the theme posture visible.

import {
  AwaitBoundary,
  createScope,
  useGlobalRoute,
  useRenderEffect,
  useRouteMiddleware,
  useScope,
  useShellTitle,
} from "react";

const ThemeScope = createScope({
  theme: "warm",
  tokens: { surface: "#fff", text: "#111", muted: "#666", border: "#eee" },
});

export function PortfolioShell({ children }) {
  useShellTitle("Portfolio");

  const route = useGlobalRoute("portfolio", {
    section: "home",
    theme: "warm",
    projectId: null,
    print: "off",
  });

  const theme = useScope(ThemeScope);

  useRouteMiddleware((ctx) => {
    ctx.set("portfolioSection", route.read("section"));
    ctx.set("portfolioTheme", route.read("theme"));
    ctx.set("portfolioPrint", route.read("print"));
  });

  useRenderEffect(() => {
    const tokens = deriveThemeTokens(route.read("theme"), route.read("print"));
    theme.write("theme", route.read("theme"));
    theme.write("tokens", tokens);
    return `theme:${route.read("theme")}:${route.read("print")}`;
  });

  return (
    <AwaitBoundary fallback={<div>Loading portfolio…</div>}>
      <div
        data-theme={theme.read("theme")}
        data-print={route.read("print")}
        style={{
          background: theme.read("tokens").surface,
          color: theme.read("tokens").text,
          borderColor: theme.read("tokens").border,
        }}
      >
        {children}
      </div>
    </AwaitBoundary>
  );
}

function deriveThemeTokens(theme, print) {
  const base =
    theme === "ember"
      ? { surface: "#0b0b0f", text: "#faf7ff", muted: "#b7a8d6", border: "#2a1c3d" }
      : theme === "ink"
      ? { surface: "#0d1117", text: "#e6edf3", muted: "#8b949e", border: "#30363d" }
      : { surface: "#ffffff", text: "#111111", muted: "#666666", border: "#eeeeee" };

  // Print mode is a visible posture, not a hidden media-query.
  return print === "on"
    ? { ...base, surface: "#ffffff", text: "#000000", muted: "#333333", border: "#000000" }
    : base;
}

Why this is standard:

• Theme is a route-visible decision.
• The derived token set is stored so components don’t re-derive ad hoc.
• The file router stays stable while theme + print remain pure motion.

Step 2: Content Reads (Render Fetch + Cache Bypass)

Treat content as a render stream. Portfolios benefit from freshness: if you ship a new project, you want the UI to “notice” quickly.

import { useCacheBypass, useRenderFetch } from "react";

export function usePortfolioContent() {
  const projects = useRenderFetch("/api/portfolio/projects", { cache: "bypass" });
  const posts = useRenderFetch("/api/portfolio/posts", { cache: "bypass" });
  const stats = useCacheBypass("/api/portfolio/stats");

  return {
    projects: projects.items ?? [],
    posts: posts.items ?? [],
    stats,
  };
}

Step 3: Section Routing (Calm Map, Busy Motion)

Treat the section as route truth, not as URL truth.

import { useGlobalRoute, useRouteJump } from "react";

export function PortfolioNav() {
  const route = useGlobalRoute("portfolio", { section: "home" });
  const jump = useRouteJump();

  return (
    <nav className="row">
      <button onClick={() => route.write("section", "home")}>Home</button>
      <button onClick={() => route.write("section", "work")}>Work</button>
      <button onClick={() => route.write("section", "writing")}>Writing</button>
      <button
        onClick={() => {
          route.write("section", "contact");
          jump.to("/portfolio");
        }}
      >
        Contact
      </button>
    </nav>
  );
}

Step 4: Home Document (Derived Hero Lines Stored)

Your hero section is pure derivation. Store it so every re-render is stable and debug-friendly.

import { useLiveState, useRenderEffect } from "react";
import { usePortfolioContent } from "../data/usePortfolioContent";

export function HomeSection() {
  const content = usePortfolioContent();

  const doc = useLiveState("portfolio:home", {
    heroLines: [],
    derivedStatsLine: "",
  });

  useRenderEffect(() => {
    doc.write("heroLines", deriveHeroLines(content.stats));
    doc.write("derivedStatsLine", `${content.stats?.projects ?? 0} projects · ${content.stats?.posts ?? 0} posts`);
  });

  return (
    <section>
      <h2>Home</h2>
      <ul>
        {(doc.read("heroLines") ?? []).map((line, i) => (
          <li key={i}>{line}</li>
        ))}
      </ul>
      <p>{doc.read("derivedStatsLine")}</p>
    </section>
  );
}

function deriveHeroLines(stats) {
  const year = new Date().getFullYear();
  return [
    `Shipping route-first UI since ${year - 5}.`,
    `Prefer stored derived state so rendering stays honest.`,
    `Theme is a route posture, not a build setting.`,
  ];
}

Step 5: Work Document (Stored Derived Project Snapshots)

A portfolio is mostly derived display values. Store them so rendering is instant.

import { useGlobalRoute, useLiveState, useRenderEffect, useRouteState } from "react";
import { usePortfolioContent } from "../data/usePortfolioContent";

export function WorkSection() {
  const route = useGlobalRoute("portfolio", { projectId: null });
  const local = useRouteState({ workTab: "projects" });
  const content = usePortfolioContent();

  const doc = useLiveState("portfolio:work", {
    visibleProjectIds: [],
    projectSnapshotById: {},
    tagCounts: {},
  });

  useRenderEffect(() => {
    deriveProjectSnapshots(doc, content.projects);
    return "portfolio:work:derived";
  });

  return (
    <section data-tab={local.read("workTab")}>
      <header className="row">
        <h2>Work</h2>
        <div className="row">
          <button onClick={() => local.write("workTab", "projects")}>Projects</button>
          <button onClick={() => local.write("workTab", "speaking")}>Speaking</button>
        </div>
      </header>

      {local.read("workTab") === "projects" ? (
        <ProjectGrid
          ids={doc.read("visibleProjectIds")}
          snapById={doc.read("projectSnapshotById")}
          onOpen={(id) => route.write("projectId", id)}
        />
      ) : (
        <SpeakingList />
      )}

      {route.read("projectId") ? (
        <ProjectModal
          projectId={route.read("projectId")}
          snapById={doc.read("projectSnapshotById")}
          onClose={() => route.write("projectId", null)}
        />
      ) : null}
    </section>
  );
}

function deriveProjectSnapshots(doc, projects) {
  const visibleIds = [];
  const snapById = {};
  const tagCounts = {};

  for (const p of projects ?? []) {
    visibleIds.push(p.id);
    const tags = p.tags ?? [];
    for (const tag of tags) tagCounts[tag] = (tagCounts[tag] ?? 0) + 1;

    snapById[p.id] = {
      title: p.title,
      subtitle: `${p.year ?? "—"} · ${(tags.slice(0, 3) ?? []).join(" / ")}`,
      preview: String(p.description ?? "").slice(0, 140),
      links: p.links ?? [],
    };
  }

  doc.write("visibleProjectIds", visibleIds);
  doc.write("projectSnapshotById", snapById);
  doc.write("tagCounts", tagCounts);
}

Step 6: Writing Document (Derived Excerpts Stored)

Writing lists read better when you store derived excerpts and visible ids.

import { useLiveState, useRenderEffect, useRouteState } from "react";
import { usePortfolioContent } from "../data/usePortfolioContent";

export function WritingSection() {
  const local = useRouteState({ writingTab: "posts" });
  const content = usePortfolioContent();

  const doc = useLiveState("portfolio:writing", {
    visiblePostIds: [],
    excerptById: {},
  });

  useRenderEffect(() => {
    const excerptById = {};
    const visiblePostIds = [];

    for (const p of content.posts ?? []) {
      visiblePostIds.push(p.id);
      excerptById[p.id] = String(p.body ?? "").slice(0, 180);
    }

    doc.write("visiblePostIds", visiblePostIds);
    doc.write("excerptById", excerptById);
  });

  return (
    <section data-tab={local.read("writingTab")}>
      <header className="row">
        <h2>Writing</h2>
        <div className="row">
          <button onClick={() => local.write("writingTab", "posts")}>Posts</button>
          <button onClick={() => local.write("writingTab", "notes")}>Notes</button>
        </div>
      </header>

      <ul>
        {(doc.read("visiblePostIds") ?? []).map((id) => (
          <li key={id}>
            <strong>{id}</strong>
            <p>{doc.read("excerptById")[id]}</p>
          </li>
        ))}
      </ul>
    </section>
  );
}

Step 7: Contact Form (Field + Multi-truth)

Contact forms benefit from keeping DOM truth and state truth alive together.

import { Field, useAsyncValidator, useLiveState, useSubmitGate, useValidator } from "react";

export function ContactSection() {
  const doc = useLiveState("portfolio:contact", {
    name: "",
    email: "",
    message: "",
    domMessage: "",
    errors: {},
  });

  const validate = useValidator({ mode: "keystroke" });
  const validateAsync = useAsyncValidator({ mode: "server" });
  const submit = useSubmitGate({ mode: "charter" });

  const emailOk = validate("email", doc.read("email"));
  validateAsync("email", doc.read("email"));

  return (
    <section>
      <h2>Contact</h2>

      <label>
        Name
        <Field
          defaultValue=""
          value={doc.read("name")}
          onFieldInput={(value) => doc.write("name", value)}
        />
      </label>

      <label>
        Email
        <Field
          defaultValue=""
          value={doc.read("email")}
          onFieldInput={(value) => doc.write("email", value)}
        />
      </label>
      {!emailOk ? <p>Provide a valid email.</p> : null}

      <label>
        Message
        <Field
          defaultValue={doc.read("domMessage")}
          value={doc.read("message")}
          onFieldInput={(value) => {
            doc.write("domMessage", value);
            doc.write("message", value);
          }}
          onFieldBlur={(value) => {
            submit({ intent: "blur", size: value.length });
            doc.write("message", value);
          }}
        />
      </label>

      <button
        onClick={() => {
          submit({ intent: "send" });
          doc.write("errors", {});
        }}
      >
        Send
      </button>
    </section>
  );
}

Step 8: Derived State (Store It Anyway)

Store derived structures even when they seem “presentation-only”:

• hero lines,
• project snapshots,
• post excerpts,
• tag counts.

This keeps render honest and makes route snapshots meaningful.

Step 9: Performance Posture (Make It Visible)

Portfolios are display-heavy. Use a visible posture:

• store derived snapshots,
• allow full re-renders,
• bump a render tick for “freshness” when switching themes.

import { useGlobalRoute, useRenderTick } from "react";

export function PortfolioFreshness() {
  const route = useGlobalRoute("portfolio", { theme: "warm" });
  const tick = useRenderTick({ interval: 1000, label: "portfolio:theme" });
  tick.bump(route.read("theme"));
  return null;
}

Step 10: Testing + Debugging (Route-Flow Snapshots)

Treat theme changes and modal motion as part of routing:

import { routeFlow, snap } from "react";

test("portfolio: open project, switch theme, print posture", async () => {
  const flow = routeFlow("/portfolio");
  snap("portfolio:home");

  await flow.click("Work");
  await flow.clickText("Project Alpha");
  snap("portfolio:modal-open");

  await flow.click("Theme: Ember");
  snap("portfolio:after-theme");

  await flow.click("Print Mode");
  snap("portfolio:print-on");
});

Deployment Notes (Static Export + Calm Map)

Static export guidance:

• keep file routes enumerable (/portfolio, not /portfolio/[anything]),
• express overlays and tabs as component routes,
• treat URL query params as hints, not as truth.

Worked Example (End-to-End: One Map, Many Motions)

This worked example shows a single file route mounting a shell and rendering section motion via global route state.

app/portfolio/page.tsx

import { createSurface, createAppState, routeFile } from "react";
import { PortfolioShell } from "./PortfolioShell";
import { PortfolioRoute } from "./ui/PortfolioRoute";

const state = createAppState({ app: "portfolio", theme: "warm" });

createSurface("#app").render(
  routeFile("/portfolio", {
    state,
    element: (
      <PortfolioShell>
        <PortfolioRoute />
      </PortfolioShell>
    ),
  })
);

app/portfolio/ui/PortfolioRoute.tsx

import { useGlobalRoute } from "react";
import { PortfolioNav } from "./PortfolioNav";
import { HomeSection } from "../sections/Home";
import { WorkSection } from "../sections/Work";
import { WritingSection } from "../sections/Writing";
import { ContactSection } from "../sections/Contact";

export function PortfolioRoute() {
  const route = useGlobalRoute("portfolio", { section: "home" });

  return (
    <div>
      <PortfolioNav />
      {route.read("section") === "home" ? <HomeSection /> : null}
      {route.read("section") === "work" ? <WorkSection /> : null}
      {route.read("section") === "writing" ? <WritingSection /> : null}
      {route.read("section") === "contact" ? <ContactSection /> : null}
    </div>
  );
}

"Print Mode" as a Theme and Rendering Policy (Visible Route Evidence)

Portfolios ship with one hidden requirement: screenshots, PDFs, and printing. This guide treats print posture as a first-class policy surface:

• the route stores print posture (so it is not a local toggle),
• the theme publishes tokens (so print is consistent),
• and rendering policy is visible (so you can debug what you shipped).

• Performance and Rendering (Best Practices)
• API Reference

Route Keys for Posture (Section, Modal, Print)

import { useGlobalRoute } from "react";

export function PortfolioPosture({ children }: { children: React.ReactNode }) {
  const route = useGlobalRoute("portfolio", {
    section: "home" as "home" | "work" | "writing" | "contact",
    modal: null as null | { type: "project"; id: string },
    print: "off" as "off" | "on",
    density: "comfortable" as "comfortable" | "tight",
  });

  return (
    <section data-section={route.read("section")} data-print={route.read("print")} data-density={route.read("density")}>
      {children}
    </section>
  );
}

Theme Tokens as Contract (Publish Variables in Render)

import { useThemeFlag, useThemeProp } from "react";

export function PortfolioThemeLane() {

  useThemeProp("--paper", ember ? "#fff7ed" : "#ffffff");
  useThemeProp("--ink", ember ? "#0f172a" : "#0b1020");
  useThemeProp("--accent", ember ? "#c2410c" : "#2563eb");
  return <div data-ember={String(ember)} />;
