A .uix file is a ZIP archive containing an HTML app, assets, and optional SQLite databases. Think of it like a PDF — but interactive, offline, and self-contained in a single file.

Install

npm install @dotuix/core
# or
pnpm add @dotuix/core

Requires Node.js ≥ 22.

Quick Start

import { UIX } from "@dotuix/core";

// Pack a project folder into a .uix archive
await UIX.pack("./my-app", "./dist/myshop.uix");

// Unpack to a directory
await UIX.unpack("./myshop.uix", "./extracted/");

// Validate
const result = await UIX.validate("./myshop.uix");
console.log(result.valid, result.errors, result.warnings);

// Read the manifest
const manifest = await UIX.manifest("./myshop.uix");
console.log(manifest.name, manifest.version);

// Open the embedded read-only database
const data = await UIX.openData("./myshop.uix", { permissions: [] });
if (data) {
  const products = data.find({
    type: "product",
    where: { category: "burgers" },
  });
  data.close();
}

// Create / load state.db in memory
const state = await UIX.createState({ uixVersion: "1.0", permissions: [] });
const id = state.insert({
  type: "cart_item",
  body: { productId: "p:001", qty: 2 },
});
const item = state.get(id);
const bytes = state.export(); // serialize for repacking
state.close();

API

Packing & Unpacking

`pack(srcDir, outputPath)`

Pack a folder into a .uix file on disk (Node.js).

Reads manifest.json from srcDir and validates it.
Compresses HTML/CSS/JS/JSON with DEFLATE. Stores .db, images, and media with STORE (no compression).
Writes atomically via .tmp → rename.

await UIX.pack("./my-app", "./dist/myshop.uix");

`packBuffer(files)`

Pack an in-memory file map into a Uint8Array (universal — browser + Node.js).

const encoder = new TextEncoder();
const buf = await UIX.packBuffer({
  "manifest.json": encoder.encode(JSON.stringify(manifest)),
  "index.html": encoder.encode("<html>…</html>"),
});

`unpack(uixPath, outDir)`

Extract a .uix archive to a directory on disk (Node.js).

await UIX.unpack("./myshop.uix", "./extracted/");

`unpackBuffer(data)`

Extract a .uix buffer into an in-memory file map (universal).

const files = UIX.unpackBuffer(data); // Record<string, Uint8Array>
const html = new TextDecoder().decode(files["index.html"]);

Validation

`validate(uixPath)` / `validateBuffer(data)`

Returns { valid: boolean; errors: string[]; warnings: string[] }.

Checks:

manifest.json exists and is valid (required fields, id format, expiry)
Entry file declared in manifest exists in the archive
File has not expired
(Warning, not error) Media/document files found outside assets/ or files/
(Warning) security.encryptedPaths lists a file not present in the archive
(Warning) security.auth: "pin" declared but encryptedPaths or keySalt missing

const result = await UIX.validate("./myshop.uix");
if (!result.valid) console.error(result.errors);
if (result.warnings.length) console.warn(result.warnings);

Manifest

`manifest(uixPath)` / `manifestFromBuffer(data)`

Read and parse the manifest from an archive.

const m = await UIX.manifest("./myshop.uix");
// m.id, m.name, m.version, m.entry, m.mode, m.permissions, …

`parseManifest(raw)` / `safeParseManifest(raw)`

Validate a raw manifest object using Zod. parseManifest throws on invalid input; safeParseManifest returns a Zod SafeParseReturnType.

Databases

Both data.db (read-only, creator-shipped) and state.db (read-write, user-owned) share the same schema:

CREATE TABLE records (
  id         TEXT    PRIMARY KEY,
  type       TEXT    NOT NULL,
  body       TEXT    NOT NULL,   -- JSON, shape decided by the .uix app
  created_at INTEGER NOT NULL DEFAULT (unixepoch()),
  updated_at INTEGER NOT NULL DEFAULT (unixepoch())
);

`openData(uixPath, opts?)` / `openDataBuffer(data, opts?)`

Open data.db from a .uix archive. Returns UIXDataDB | null (null if the archive has no data.db).

const db = await UIX.openData("./myshop.uix", { permissions: ["raw-sql"] });
if (db) {
  db.find({ type: "product" });
  db.find({ type: "product", where: { category: "مشويات" }, limit: 10 });
  db.get("product:001");
  db.raw("SELECT body FROM records WHERE type = ? ORDER BY rowid", ["product"]);
  db.close();
}

`createState(opts)` → `UIXStateDB`

Create a fresh state.db in memory, or load from a seed.

const state = await UIX.createState({ uixVersion: "1.0" });

// With a seed (from manifest.state.seed = true)
const seed = files["state.db"]; // Uint8Array from unpackBuffer
const state = await UIX.createState({
  uixVersion: "1.0",
  seed,
  permissions: [],
});

`openStateFromFile(statePath, opts?)` → `UIXStateDB`

Load an existing state.db file from disk (Node.js). Useful for CLI export commands.

assets/ and files/ are conventions, not requirements. Files can live anywhere in the archive and are referenced via normal relative HTML paths. The validator emits a warning (never an error) if media files are found outside these folders.

manifest.json

    "auth": "pin",
    "encryptedPaths": ["data.db", "files/annex-a.pdf"],
    "kdf": "PBKDF2-SHA256",
    "kdfIterations": 200000,
    "keySalt": "base64url-random-salt",
    "maxOpens": 3,
    "screenshot": false
  },
  "signature": {
    "algorithm": "Ed25519",
    "publicKey": "base64url-public-key",
    "value": "base64url-signature",
    "signedAt": "2026-05-19T10:00:00Z"
  }
}

mode: kiosk (locked UI, no browser chrome) or window (developer preview).

permissions: local-storage, print, clipboard-write, fullscreen, raw-sql.

network: blocked (default) or allowed.

security fields (all optional — omit the block for regular apps):

Field	Default	Description
`auth`	`"none"`	`"pin"` — viewer prompts for PIN before opening
`encryptedPaths`	`[]`	Paths inside the archive encrypted with AES-256-GCM
`kdf`	`"PBKDF2-SHA256"`	Key derivation function
`kdfIterations`	`200000`	PBKDF2 iterations (higher = slower brute-force)
`keySalt`	—	Base64url random salt stored in manifest (safe to store publicly)
`maxOpens`	unlimited	Max opens tracked by the viewer locally — file cannot bypass this
`screenshot`	`false`	`true` = viewer blocks OS screenshot API (desktop only)

Compression

File type	ZIP method
HTML, CSS, JS, JSON, text	DEFLATE (level 6)
PNG, JPG, JPEG, WEBP, GIF, SVG, MP4, MP3, WEBM, WASM	STORE
`.db` files	STORE
