Indexeddb

This library was created only to be used by members of 'steadfast developers', but if you find it and it helps you feel free to use it.

Installation

npm install @steadfast-devs/indexeddb

Usage

First you need to create a .schema file, this will describe the collection structure. For example:

//users.schema
import {Schema} from '@steadfast-devs/indexeddb';
export const UserSchema: Schema = {
  primaryKey: 'username',
  properties: {
    id: { type: 'string'},
    username: { type: 'string', primary: true },
    password: { type: 'string' },
  },
  required: ['username', 'password'],
};

Then you need to register the collections

import { IndexedDataBase } from '@steadfast-devs/indexeddb';

// You need use the static method registerCollection 
IndexedDataBase.registerCollection('users', UserSchema);

// Then you can instantiate the IndexedDataBase class. You need to pass the database name and the version
const db = new IndexedDataBase('myDatabase', 1);

Now you can use the database

//Create a new user
db.addData('users', {
    id: '1',
    username: 'myUsername', 
    password: 'myPassword'
});

//Get all users
db.getAllData('users').then(users => {
    console.log(users);
});

//Get a user by username
db.getData('users', 'myUsername').then(user => {
    console.log(user);
});

Example Angular Service

...
import { IndexedDataBase } from '@steadfast-devs/indexeddb';
import { UserSchema } from './user.schema';
@Injectable({
  providedIn: 'root'
})
export class dbServices{
    public instance: IndexedDataBase;
    constructor(){
        ...
        IndexedDataBase.registerCollection('users', UserSchema);
        ...
        this.instance = new IndexedDataBase('myDatabase', 1);
    }
}

Version Notes

1.0.0-alpha.1.0.0 to 2.0.0-alpha.1.1.0

• Some methods were changed to be more intuitive

example:

// Before
// First we need to instantiate the database
import { IndexedDataBase } from '@steadfast-devs/indexeddb';
const db = new IndexedDataBase('myDatabase', 1);
// Then we need to create the collection
db.createCollection('users', UserSchema);

// After
// We need to register the collection first
import { IndexedDataBase } from '@steadfast-devs/indexeddb';
IndexedDataBase.registerCollection('users', UserSchema);
IndexedDataBase.registerCollection('task', TaskSchema);
...
// Then we can instantiate the database
const db = new IndexedDataBase('myDatabase', 1);
