or you can follow this link for installing Akita in your project.

Step 5: Now go to src –> app from your vs code. Right click on the app folder and create a new folder named Store.

Step 6: Right click on the Store folder and create a new file named Session.Store.ts and paste this code.

import { Injectable } from '@angular/core';
import { EntityStore, Store, StoreConfig } from '@datorama/akita';

export interface User {
   id: number;
   token: string;
   name: string;
  providedIn: 'root'

@StoreConfig({ name: 'session', idKey: 'id' })
export class SessionStore extends EntityStore<User> {
  constructor() {
    super() ;

Step 7: Right click on the Store folder and create another new file named Session.Query.ts and paste this code.

import { Injectable } from '@angular/core';
import { Query, QueryEntity } from '@datorama/akita';
import { SessionStore, User } from './Session.Store';

    providedIn: 'root'

export class SessionQuery extends QueryEntity<User> {
  constructor(protected store: SessionStore) {

Step 8: Now go to app.component.ts file and paste this following code

import { Component } from '@angular/core';
import { SessionQuery } from './Store/Session.Query';
import { SessionStore, User } from './Store/Session.Store';
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']

export class AppComponent {
  title = 'internal-audit';
   constructor(protected store: SessionStore, query: SessionQuery) {
    // Create a data
    const user : User =
      id : 1,
      token : '$%!',
      name : 'Anik'

Step 9: Now go to terminal and paste this command to run the project.

npm start
Step 10: Now go to browser and run http://localhost:4200/  and go to inspect –> console
Here you can see a data is inserted into a store and get the data from the store.Here we have use upsert method for inserting data into a store which is provided by Akita. This method  is insert data if there is no record into store, if there is a data already there then it will update the data. And to see all the data from the store we used getAll() method.

That’s All.
