Expressa Overview
Expressa is a content management system (CMS) that powers database-driven websites using JSON schemas. With Expressa, you can create RESTful APIs and manage permissions for your collection endpoints in a Django-like admin interface. The platform provides automatic API documentation generation through Swagger and supports browser-based and Node.js clients.
Main Features
- Admin UI: Create blog collections and posts, manage CRUD (Create, Read, Update, Delete) permissions, and define schema-based forms for data-driven development.
- JSON Schemas: Define your collection endpoints using JSON schema instead of custom code, making it easy to extend and reuse schema definitions in your frontend.
- Per-Collection Storage: Store collection data in MongoDB, PostgreSQL, or JSON files (ideal for version control).
- Automatic REST APIs: Generate RESTful APIs for your collections with minimal code required.
- Permission Management: Manage CRUD permissions for each collection endpoint through the admin interface.
Getting Started
Installing Expressa is a breeze. Simply create a new project directory, initialize a new npm project, and install Expressa and Express:
```bash
mkdir myapp
cd myapp
npm init
npm install expressa express
Create an `app.js` file with the following code (or copy the middle three lines into your existing Express app):
javascript
var express = require('express');
var app = express();
// ...
```
With Expressa, you can start building your database-driven website and RESTful APIs in no time.
