Wate Engine is a CMS engine for Node.js/Express applications, using SQLite as its database and EJS for templating. Current stable version is 3.19.5 (release cadence: irregular, last updated 2021). It dynamically generates CRUD interfaces from database tables, similar to a low-code admin panel. Differentiators: minimalist, no external dependencies beyond Express and SQLite3; entirely DB-driven schema without migrations; supports multi-tenant and plugin architecture. Designed for small to medium projects needing a quick admin backend.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default
✓ const Wate = require('wate-engine')
✗ import Wate from 'wate-engine'
Package uses CommonJS; ESM import may fail without transpilation.
Wate
✓ const Wate = require('wate-engine').Wate
✗ const { Wate } = require('wate-engine')
Wate is a property on the default export, not a named export in CommonJS.
types
✓ const { Wate } = require('wate-engine')
✗ import { Wate } from 'wate-engine'
Type definitions are not shipped; use @types/wate-engine if available.

Initializes Wate Engine with Express, SQLite database, and mounts admin router at /admin.

const express = require('express'); const Wate = require('wate-engine'); const app = express(); app.use(express.json()); app.use(express.urlencoded({ extended: true })); app.set('view engine', 'ejs'); const wate = new Wate({ dbPath: './database.sqlite', secret: 'mysecret', plugins: [] }); app.use('/admin', wate.router); const PORT = process.env.PORT || 3000; app.listen(PORT, () => console.log(`Running on ${PORT}`));
Debug
Known issues
breakingUpgrading from v2 to v3: database schema auto-migration may drop custom columns.
fix
Backup database before upgrade; manually migrate using migration scripts.
affects: >=3.0.0 <3.0.0
deprecatedThe 'plugins' option in constructor is deprecated since v3.5.0. Use Wate.plugin() instead.
fix
Replace new Wate({ plugins: [...] }) with wate = new Wate({...}); wate.plugin(plugin1); wate.plugin(plugin2);
affects: >=3.5.0
gotchaDefault session store is memory-based; sessions lost on restart.
fix
Configure a persistent session store (e.g., connect-sqlite3).
affects: all
breakingRemoved support for Node.js <4.6.1 in v3.0.0.
fix
Upgrade Node.js to >=4.6.1.
affects: >=3.0.0
deprecatedThe built-in file upload handler is deprecated in v3.10.0; will be removed in v4.
fix
Migrate to a dedicated file upload module (e.g., multer).
affects: >=3.10.0
