Pamlight Angular Client SDK

Pamlight is a service for managing realtime connections to your database with whatever technology it is powered by. This tool (Angular Client SDK) is used to connect an Angular 2+ project from client domains to pamlight endpoints at a high level.

Getting started

For more detailed instructions and guides on client side integration, check Pamlight client integration and also how Pamlight works, see our official documentations here.

Installation

Install pamlight angular client sdk via npm by running the following command:

npm install @pamlight/ngx-client --save

Usage

Register the NgxPamlightModule in your app module (or any other module you want to use it).

import { NgxPamlightModule } from '@pamlight/ngx-client';

import { NgxPamlightModule } from '@pamlight/ngx-client';

@NgModule({
 declarations: [],
 imports: [
   ...,
   NgxPamlightModule
 ],
 providers: [],
 bootstrap: []
})
export class AppModule {}

Use NgxPamlightService service in your component or in another service like below:

import { Component, OnInit } from '@angular/core';
import { NgxPamlightService } from '@pamlight/ngx-client';

@Component({
    selector: 'app-component-a',
    templateUrl: './component-a.component.html',
    styleUrls: ['./component-a.component.scss']
})
export class ComponentName implements OnInit {    
    constructor(
        private ngxPamlightService: NgxPamlightService
    ) { }

    ngOnInit() {
        // code actions here
    }
}

Initialize

Connect Pamlight client by initializing with the service. Its is adviceable to run init() method in a singleton service so as to ensure only a single instance is running.

import { Injectable } from '@angular/core';
import { NgxPamlightService } from '@pamlight/ngx-client';

@Injectable()
export class ServiceName {
    constructor(
        private ngxPamlightService: NgxPamlightService
    ) {
        this.initPamlight();
    }

    private initPamlight(): void {
        // replace `PROJECT_ID` with your project ID from Pamlight dashboard
        const projectId: string = `PROJECT_ID`;

        this.ngxPamlightService.init().then(() => {
            console.log('Pamlight connected successfully');
        }).catch(err => {
            throw Error(err);
        });
    }
}

sync data from database

Reading and subscribing to data changes in your database is straight forward. The read method returns an rxjs observable which can be subscribe to for subsequent data changes. For example, to get a User document from data base by userId, you could do something like this:

const routeId = 'getUserByUserID';
const query = {
    userId: `USER_ID`
};

this.ngxPamlightService.read<User>(routeId, query).subscribe(user => {
    console.log(user);
});

write data to database

Writing data to your database is by calling the write method on the connected client object. This returns a promise object with result if expected or void otherwise.

const routeId = 'updateUserProfile';
const payload = {
  firstName: 'Alice',
  lastName: 'Bob',
  age: 32
};

this.ngxPamlightService.write(routeId, payload, true).then((result) => {
  console.log(result);
}).catch((e) => {
  throw Error(e);
});
