Use of Inherited Sharing in Apex Class

This post explains the use of inherited sharing in apex class
If you specify inherited sharing Keyword on an Apex class,  which allows the class to run in the sharing mode of the class that called it. Using inherited sharing enables you to pass security review and ensure that your privileged Apex code is not used in unexpected or insecure ways.

1. An Apex class with inherited sharing runs as with sharing when used as a Visualforce page controller, Apex REST service, or an entry point to an Apex transaction.
2. An Apex class with Inherited Sharing is being called from some other class which is having without sharing setting, then it will run in without sharing mode.

Example

This example declares an Apex class with inherited sharing and a Visualforce invocation of that Apex code. Because of the inherited sharing declaration, only opportunities for which the running user has sharing access are displayed. If the declaration is omitted, even opportunities that the user has no rights to view are displayed due to the insecure default behavior of omitting the declaration.
Apex Class

public inherited sharing class OpportunityMethods {
    public list<Opportunity> getAllTheOpps(){
        return [SELECT Id, Name, StageName FROM Opportunity];
    }
}

Visualforce page

<apex:page controller="OpportunityMethods">
    <apex:repeat value="{!getAllTheOpps}" var="record">
        {!record.Name}
    </apex:repeat>
</apex:page>

How to Enforce Field-Level Security Permissions for SOQL Queries?

This post explains how to enforce field level security permissions for SOQL queries,
In Spring' 19 release salesforce introducing this feature, at the time of writing this post this feature in Beta stage.
Use the WITH SECURITY_ENFORCED clause to enable checking for the field- and object-level security permissions on SOQL SELECT queries, including subqueries and cross-object relationships. Although performing these checks was possible in earlier releases, this clause substantially reduces the verbosity and technical complexity in query operations.

How it Works?

If fields or objects referenced in the SELECT clause using WITH SECURITY_ENFORCED are inaccessible to the user, an exception is thrown, and no data is returned.

Example: 1

SELECT Id, Name, StageName, ClosedDate FROM Opportunity WITH SECURITY_ENFORCED

if the stage name is inaccessible to the user it throws an exception insufficient permissions. and no data return.

Example: 2

SELECT Id, (SELECT FirstName, LastName FROM Contacts), (SELECT Description, StageName, CloseDate FROM Opportunities) 
       FROM Account WITH SECURITY_ENFORCED

if the First Name, stage name is inaccessible to the user it throws an exception insufficient permissions. and no data return.

How to Read REST API GET Parameters in Apex

This post explains How we can read the REST API GET parameters in Apex
We can read the parameters based on URL

Example:1

URL: /services/apexrest/getContactdetails?accountId=Accountd&leadSource=Web
Rest Method: GET
Demo:

@RestResource(urlMapping='/getContactdetails/*')
global class RESTServiceDemoClass {
    
    @HttpGet
    global static list<Contact> getContactList() {
        String strAccId = '';
        String strLeadSource = '';
        list<Contact> lstCons;
        RestRequest restReq = RestContext.request;
        RestResponse restRes = RestContext.response;
        // Reading parametrs from URL
        strAccId = restReq.params.get('accountId');
        strLeadSource = restReq.params.get('leadSource');
        if(!String.isBlank(strAccId) && !String.isBlank(strLeadSource)) {
            lstCons = [Select Id, Name, Email FROM Contact WHERE AccountId =:strAccId AND LeadSource =: strLeadSource];
        }
        return lstCons;
    }
}

above class return the list of contacts based on passing parameters accountId and lead source
Example URL
/services/apexrest/getContactdetails?accountId=0017F00000idCUi&leadSource=Web

        String strLeadSource = '';
        list<Contact> lstCons;
        RestRequest restReq = RestContext.request;
        RestResponse restRes = RestContext.response;
        // Reading parametrs from URL
        strAccId = restReq.requestURI.substring(restReq.requestURI.lastIndexOf('/') + 1);
        strAccId = strAccId.left(strAccId.lastIndexOf('&'));
        strLeadSource = restReq.requestURI.substring(restReq.requestURI.lastIndexOf('&') + 1);
        if(!String.isBlank(strAccId) && !String.isBlank(strLeadSource)) {
            lstCons = [Select Id, Name, LeadSource FROM Contact WHERE AccountId =:strAccId AND LeadSource =: strLeadSource];

Introduction to Lightning Web Components(LWC)

This post explains the
1. What is Lighting Web Component(LWC)?
2. How to Create a Lightning Web Component with Non-scratch org.

What is Lighting Web Component(LWC)?
1. LWC is a new Programming Language modal for building a Lightning Components
2. LWC uses modern web programming standards, shadow DOM, modules and ECMAScript7.
3. LWC coexist and interoperate with the original Aura programming model, and delivers unparalleled performance.
How to Create a Lightning Web Component?
You cannot create LWC directly from your developer console. you need to SFDX to create your lightning web component.

Step 1: Steps to set up an SFDX with vs code

1. Download and Install Salesforce CLI
2. Download vs code From this link and install.
Note: Once install the Salesforce CLI You can verify using below command
sfdx --version

Installing Salesforce Extensions in vs code
1. Open vs code install Salesforce extension pack

2. Install Lightning Web Components Extension

Step 2: Signup to pre-release org

Sign up for a pre-release Developer Edition Org using below link

https://www.salesforce.com/form/signup/prerelease-spring19/

Note: Once you create the Pre-release developer org add my domain for the Org otherwise custom developed components are not visible in the app builder

Step 3: Upgrade Pre-Release version of Salesforce CLI

Use below command to upgrade the Pre-release version of Salesforce CLI
sfdx plugins:install salesforcedx@pre-release

Step 4: Creating the SalesforceDx Project

Go to your vs code editor

Press "CTRL + SHIFT + P" then select SFDX:Create Project with Manifest

Enter project Name and Select Folder

Step 5: Authorize an org

Press "CTRL + SHIFT + P" then select SFDX: Authorize an Org

this command opens your default browser then login to your pre-release developer org

once logged in to your org you may close your browser

Step 6: Creating Lightning Web Components

Press "CTRL + SHIFT + P" then select SFDX: Create Lightning Web Component

Then Select Folder where you want to save your LWC component

Then give your component name

verify component under lwc folder

Example

LWCDemoComponent.html

<template>
    <lightning-card title="Contact" icon-name="standard:contact">

        <lightning-record-form object-api-name={objectApiName} record-id={recordId} 
                               fields={fields}></lightning-record-form>

    </lightning-card>
</template>

LWCDemoComponent.js

import { LightningElement , api, track} from 'lwc';

export default class LWBDemoComponent extends LightningElement {
    @api recordId;
    @api objectApiName;
    @track fields = ['Name', 'Title', 'Phone', 'Email'];
}

LWCDemoComponent.js-meta.xml

<?xml version="1.0" encoding="UTF-8"?>
<LightningComponentBundle xmlns="http://soap.sforce.com/2006/04/metadata" fqn="LWBDemoComponent">
    <apiVersion>45.0</apiVersion>
    <isExposed>true</isExposed>
      <targets>
    <target>lightning__AppPage</target>
    <target>lightning__RecordPage</target>
    <target>lightning__HomePage</target>
  </targets>
</LightningComponentBundle>

Step 7: Deploy your component in Org

once you complete the code, go to your lwc folder then right click on the component folder
select SFDX: Deploy Source to Org

go to contact record page editor you can verify your components

That's it
