Welcome to ComposeDB

ComposeDB is a next-generation composable database system that offers several APIs to make database interactions seamless and efficient. In this blog post, we will introduce ComposeDB and explore some of its useful APIs with code snippets and examples. Additionally, we will build a simple application to demonstrate the practical usage of these APIs.

Getting Started

To use ComposeDB, you first need to install the ComposeDB package:

npm install composedb

API Examples

Create a Database

 const { createDatabase } = require('composedb');
async function initDatabase() {
    const db = await createDatabase('myDatabase');
    console.log('Database created:', db.name);
}
initDatabase(); 

Insert a Record

 const { insertRecord } = require('composedb');
async function addRecord(db) {
    const record = { name: 'John Doe', age: 30 };
    await insertRecord(db, 'users', record);
    console.log('Record inserted:', record);
}
addRecord(db); 

Read Records

 const { readRecords } = require('composedb');
async function fetchRecords(db) {
    const users = await readRecords(db, 'users');
    console.log('Users:', users);
}
fetchRecords(db); 

Update a Record

 const { updateRecord } = require('composedb');
async function modifyRecord(db, userId, update) {
    await updateRecord(db, 'users', userId, update);
    console.log('Record updated:', update);
}
modifyRecord(db, 1, { age: 31 }); 

Delete a Record

 const { deleteRecord } = require('composedb');
async function removeRecord(db, userId) {
    await deleteRecord(db, 'users', userId);
    console.log('Record deleted:', userId);
}
removeRecord(db, 1); 

Building a Simple Application

Now, let’s build a simple application with the APIs mentioned above. This app will manage user data including creating, reading, updating, and deleting user records.

 const { createDatabase, insertRecord, readRecords, updateRecord, deleteRecord } = require('composedb');
async function main() {
    const db = await createDatabase('userAppDB');
    console.log('Database initialized.');

    await insertRecord(db, 'users', { name: 'Jane Doe', age: 28 });
    console.log('User Jane Doe added.');

    await insertRecord(db, 'users', { name: 'Alice Johnson', age: 34 });
    console.log('User Alice Johnson added.');

    const users = await readRecords(db, 'users');
    console.log('All Users:', users);

    await updateRecord(db, 'users', 1, { age: 29 });
    console.log('Updated Jane Doe age.');

    await deleteRecord(db, 'users', 2);
    console.log('Deleted Alice Johnson.');
}
main(); 

By following these examples, you can efficiently manage your database operations using ComposeDB.
