json Adapter
How to us
const OrbDB = require('orb');
const OrbDBSchema = require('orb/schema');
const fs = require('fs').promises;
const path = require('path');
// Define JSON Adapter
const adapter = require('orb/adapters/jsonAdapter');
const dbPath = path.join(__dirname, './db.json');
let orbDB;
orbDB = new OrbDB.Json(new adapter(dbPath));
const schemaInstance = new OrbDBSchema(orbDB);
// Define your model here
const userModel = {
name: 'User',
fields: {
id: { type: 'number', required: true },
name: { type: 'string', required: true },
age: { type: 'number', required: false }
}
};
let init = ( async () => {
// initialize database
schemaInstance.addModel(userModel);
await schemaInstance.createSchema();
})
init();
// Example usage: Add a user
const newUser = { id: 1, name: 'John Doe', age: 30 };
orbDB.insert(userModel.name, newUser);
const dbData = await fs.readFile(dbPath, 'utf8');
const jsonData = JSON.parse(dbData);
// Fetch all users from the database
const users = await orbDB.get(userModel.name);
console.log('Users:', users);
// Example usage: Update a user
const updatedUser = { name: 'Blaze' };
orbDB.update(userModel.name, 1, updatedUser);
const dbData = await orbDB.get(userModel.name);
const updatedUserData = dbData.find(user => user.id === 1);
// Fetch updated users from the database
const updatedUsers = await orbDB.get(userModel.name);
console.log('Updated Users:', updatedUsers);
// Example usage: Delete a user
orbDB.delete(userModel.name, 1);
const dbData = await orbDB.get(userModel.name);
const deletedUserData = dbData.find(user => user.id === 1);
Sqlite Adapter
How to use
const OrbDB = require('orb');
const sqlite3 = require('sqlite3').verbose();
const fs = require('fs').promises;
const path = require('path');
const adapterModule = require('orb/adapters/sqliteAdapter'); // Import the adapter class
let orbDB;
let sqliteAdapterInstance;
const dbPath = path.join(__dirname, './db.sqlite3');
sqliteAdapterInstance = new adapterModule(dbPath); // Create an instance of SQLiteAdapter
await sqliteAdapterInstance.init(); // Initialize SQLite connection
// Create the schema for the test table
await sqliteAdapterInstance.createSchema('test_table', {
id: { type: 'integer' },
name: { type: 'string' },
isActive: { type: 'boolean' },
});
// Initialize OrbDB with the SQLite adapter instance
orbDB = new OrbDB.Sql(sqliteAdapterInstance);
// Add record
const newUser = { id: 1, name: 'John Doe', isActive: false };
await orbDB.insert('test_table', newUser);
// Update reord
const updatedUser = { name: 'Blaze' };
await orbDB.update('test_table', 1, updatedUser);
// Delete record
await orbDB.delete('test_table', 1);
Hashing data
how to use:
const HashUtility = require("orbdb/utils/hash");
const sampleData = "Data to be hashed";
const hash = HashUtility.hash(sampleData);
const isMatch = HashUtility.verify(sampleData, hash);
if(isMatch){
console.log("Hash match");
}
Sanitizing Data
Added data sanitization. special characters from input data will now be striped and only clean data is stored in the database
making sure your system is secure and data integrity is intact
Adaptors:
Now json and sqlite adapters are fully functional and ready for use
Why OrbDB?
Here are the advantages of using OrbDB, based on its features and design principles:
1. JSON and SQLite Adapter Support
OrbDB allows developers to choose between lightweight JSON-based storage or robust SQLite databases, offering flexibility for various project requirements.
2. Dynamic Schema Management
- OrbDB provides dynamic schema creation, making it easier to define and manage models directly within your application.
- Developers can work with multiple models simultaneously without additional setup.
3. Custom Session Management
- With its session class, OrbDB introduces commit and rollback functionality, making it easier to manage transactions and ensure data integrity.
4. Simplified Development
- By abstracting away database operations, OrbDB lets developers focus on writing application logic rather than low-level database queries.
5. Auto Incrementing IDs
- Automatically assigns and increments IDs for entries in tables, reducing the overhead of managing primary keys.
6. Error Handling and Validation
- Ensures schema compliance by validating data types and properties at runtime.
- Provides meaningful error messages, helping developers debug effectively.
7. Cross Platform Compatibility
- Designed to work seamlessly across operating systems, including Linux, Windows, and MacOS.
8. Lightweight and Scalable
- OrbDB is ideal for small to medium-sized applications and can scale effectively by switching between adapters.
9. Easy Integration
- With a modular design, OrbDB can be integrated into existing applications with minimal effort.
- Future-proofed for additional adapters or features, making it a long-term investment.
10. Developer Friendly APIs
- Intuitive and concise APIs make it easier for developers to perform operations like inserts, updates, and schema management without a steep learning curve.
11. Open Source and Community Driven
- The project being open source fosters community contributions, ensuring continuous improvement and access to a wider knowledge base.
These advantages position OrbDB as a versatile ORM that caters to both beginner and experienced developers, promoting productivity and efficiency. It is particularly appealing for projects requiring lightweight and flexible data management solutions.
