@profullstack/profile

One user profile for every Profullstack property. Six fields, in this order, everywhere:

column	what it holds	example
email	the contact address, lower-cased	ada@acme.com
first_name	as typed, case kept	Ada
last_name	as typed, case kept	Lovelace
company_domain	bare domain, no scheme or www.	acme.com
job_title	as typed, whitespace cleaned	VP Engineering
linkedin_url	canonical profile URL	https://www.linkedin.com/in/ada-lovelace

The order is the CSV column order Explee, Apollo and cli-tools user-export --full read, so an export from any property imports anywhere without remapping.

What the package gives a property:

• Validation and normalization. acme.com/about, https://www.Acme.com and @acme.com all become acme.com. Any LinkedIn URL, in/x or bare handle becomes the canonical URL. A link in a name box is refused as spam. Names are never "corrected" (McDonald stays McDonald).
• Company from a work email. A blank company domain is filled from the signup email unless it is a personal or relay mailbox (gmail, proton, passmail and so on).
• Signup form fields. As an HTML string for server-rendered pages, and as a React component, with the right autocomplete tokens so browsers fill them.
• Storage on whatever the property already runs: postgres.js, Bun SQL, node-postgres, libSQL/Turso, @profullstack/libsql-pg, bun:sqlite, better-sqlite3, or supabase-js on the server. Either its own user_profiles table, or the columns added to an existing profiles/users table.
• GET/PUT/PATCH /api/v1/me/profile handlers on Web-standard Request/Response, for Next and Hono alike.
• A CLI and an MCP server (profile), including profile export in contract order.

npm i @profullstack/profile

It has no dependencies. postgres, @libsql/client and react are optional peers; the property already has whichever it uses.

Required fields

By default a signup must give email, first_name and last_name; the other three are offered and marked optional, because every required box costs signups. A property that sells to companies passes LEAD_REQUIRED (adds company_domain and job_title, the fields an outbound tool will not import a lead without).

import { validateProfile, LEAD_REQUIRED } from "@profullstack/profile";
validateProfile(form, { required: LEAD_REQUIRED });

Adopting it in a property

1. Schema. Call migrate() on boot or in the migration runner. It creates user_profiles, or adds only the missing columns to the table you name. Postgres takes an advisory lock, so concurrent boots are safe. On Supabase (no DDL through supabase-js), put profile schema output in a migration file.
2. Signup form. Add the fields beside the email box.
3. Signup handler. Validate before creating the user, save after.
4. Profile page. Mount the handlers and let people fill in what they skipped.
5. Backfill. Copy any name or company columns the property already has, using fillBlanks so nothing typed is overwritten.

Next on Postgres (postgres.js)

// lib/profile.js
import sql from "@/lib/db";
import { createProfileStore } from "@profullstack/profile";
export const profiles = createProfileStore(sql); // or { table: "profiles", key: "id" }

// app/signup/page.jsx (a server component posting to a route handler or a server action)
import { ProfileFields } from "@profullstack/profile/react";

<form action={signup}>
  <ProfileFields />
  <button>Send me a sign-in link</button>
</form>

// the signup action / POST handler
import { validateProfile, saveSignupProfile } from "@profullstack/profile";

const check = validateProfile(formData);
if (!check.ok) return { errors: check.errors };
const user = await createUserAndSendMagicLink(check.profile.email);
await saveSignupProfile(profiles, user.id, formData, { email: user.email });

// app/api/v1/me/profile/route.js
import { createProfileHandlers } from "@profullstack/profile";
import { profiles } from "@/lib/profile";
import { currentUser } from "@/lib/session";

export const { GET, PUT, PATCH } = createProfileHandlers({
  store: profiles,
  getUser: (req) => currentUser(req), // { id, email } or null
});

On a signed-in profile settings form, enable URL prefill without adding another API route:

<ProfileFields
  values={values}
  onChange={setValues}
  importOpenProfile
/>

The importer reads an OpenProfile.md URL through the authenticated GET /api/v1/me/profile?openprofile=<url> handler, then fills only matching fields. It does not save; the person reviews and submits the existing form. The server follows only public HTTPS hosts, rechecks redirects, caps the document at 256 KB, and returns normalized contact fields rather than the source document. Server-rendered forms can pass importOpenProfile: true to renderProfileFields and include PROFILE_ENHANCE_SCRIPT on the page.

After an account connection, server code can save the linked profile into blank fields while preserving anything the person already entered:

await saveOpenProfileContact(profileStore, user.id, coinpayUser.openprofile_url);

Hono on Turso

import { createClient } from "@libsql/client";
import { createProfileStore, mountProfileRoutes, renderProfileFields, PROFILE_ENHANCE_SCRIPT } from "@profullstack/profile";

const profiles = createProfileStore(createClient({ url, authToken }));
await profiles.migrate();
mountProfileRoutes(app, { store: profiles, getUser: (req) => sessionUser(req) });

app.get("/signup", (c) =>
  c.html(`<form method="post" action="/signup">
    ${renderProfileFields()}
    <button>Sign up</button>
  </form><script>${PROFILE_ENHANCE_SCRIPT}</script>`),
);

Supabase

Browsers talk only to /api, so the store runs on the server with the service client:

const profiles = createProfileStore(supabaseAdmin, { table: "profiles", key: "id" });

npx @profullstack/profile schema --table profiles --key id > supabase/migrations/20261026000000_profile_fields.sql

(For an existing table, write the alter table ... add column if not exists lines yourself, or run profile migrate with DATABASE_URL pointing at the database.)

Store API

const profiles = createProfileStore(db, { table = "user_profiles", key = "user_id" });
await profiles.migrate();                        // { created, added: [columns] }
await profiles.save(userId, { job_title: "CTO" }); // only given fields; null clears
await profiles.fillBlanks(userId, enriched);      // never overwrites what a person typed
await profiles.get(userId);  await profiles.getByEmail(email);
await profiles.list({ limit, after, since });     // keyset pages: { profiles, next }
for await (const p of profiles.all()) { ... }
await profiles.remove(userId);

A hand-written adapter is { dialect: "postgres" | "sqlite", query(text, params) } and receives ? placeholders. A Postgres client wrapped to look like @libsql/client (anything with execute() that is not @profullstack/libsql-pg) is taken for SQLite: pass dialect: "postgres".

There is no foreign key to a users table: the host's may be named anything or live elsewhere. Deleting a user is the host's job, so call remove() there.

CLI and MCP

export DATABASE_URL=postgres://...      # or libsql://..., file:app.db (TURSO_AUTH_TOKEN for Turso)
profile migrate
profile get <user-id>
profile find ada@acme.com
profile set <user-id> --job-title CTO --linkedin in/ada-lovelace
profile check --company-domain https://www.acme.com/about
profile export --complete > leads.csv     # only rows with every lead field
profile export --format tsv --since 2026-10-01
profile mcp                               # tools: get_profile, update_profile, validate_profile, export_profiles

--table and --key (or PROFILE_TABLE, PROFILE_KEY) point it at an existing table.
