Level Up Your SharePoint Skills: SPFx Best Practices for Coders

784 words, 4 minutes read time.

The world of SharePoint development is constantly evolving, and mastering the skills required to build robust and scalable applications is crucial for any serious coder. With the rise of SPFx, it’s essential to stay up-to-date with best practices and patterns that can help take your skills to the next level.

Introduction

The SharePoint Framework (SPFx) has revolutionized the way developers build custom applications for Microsoft 365. With its powerful combination of web development, DevOps, and business intelligence capabilities, SPFx offers a unique opportunity for coders to create innovative solutions that can transform businesses. In this article, we’ll explore some essential best practices for SPFx developers, providing practical guidance on how to level up your skills and build high-quality applications.

Understanding the Power of Modularize

import { declareCustomElement } from '@microsoft/sp-core-library'; import { BaseClientSideWebPart } from '@microsoft/sp-webpart-base';@declareCustomElement({name: 'MyWebPart',metadata: {description: {type: String,default: 'This is a custom web part'}}})export class MyWebPart extends BaseClientSideWebPart {render() {return Hello World!;}onInit() {this.properties.description = 'This is an updated description'; }}

Modularize is a powerful pattern in SPFx development that allows you to break down complex applications into smaller, reusable components. By doing so, you can improve maintainability, scalability, and overall quality of your codebase. In this article, we’ll explore the benefits of modularize and provide guidance on how to implement it effectively.

Using Dependency Injection for Loose Coupling

import { injectable } from 'tsyringe';@injectable()export class MyService {private logger: Logger;constructor(logger: Logger) {this.logger = logger;}public doSomething() {this.logger.log('Doing something');}}

Dependency injection is a design pattern that allows you to decouple components from each other, making it easier to test, maintain, and extend your codebase. In SPFx development, dependency injection is particularly useful when working with services and libraries that need to be injected into your web part or component. In this section, we’ll explore the benefits of using dependency injection in SPFx and provide guidance on how to implement it effectively.

Optimizing Performance with Caching

import { CacheManager } from 'sp-core-library';const cache = new CacheManager();cache.add('myKey', 'myValue');console.log(cache.get('myKey')); // Output: 'myValue'

Optimizing performance is crucial in any web application, and SPFx is no exception. One effective way to improve performance is by using caching mechanisms. In this section, we’ll explore the benefits of caching in SPFx and provide guidance on how to implement it
effectively.

Best Practices for Unit Testing

import { TestBed } from '@angular/core/testing';import { MyService } from './my.service';describe('MyService', () => {beforeEach(() => {TestBed.configureTestingModule({providers: [MyService]});});it('should do something', () => {const service = TestBed.get(MyService);expect(service.doSomething()).toBe(true);});});

Unit testing is an essential part of any software development workflow. In SPFx, unit testing allows you to ensure that your components and services are working as expected, reducing the risk of bugs and errors in your application. In this section, we’ll explore best practices for unit testing in SPFx and provide guidance on how to write effective tests.

Conclusion / Next Steps

In this article, we’ve explored essential best practices for SPFx developers, including modularize, dependency injection, caching, unit testing, and more. By following these guidelines, you’ll be able to build high-quality applications that are scalable, maintainable, and efficient.

Next steps include implementing the patterns and techniques discussed in this article. Start by identifying areas where you can apply modularize, then experiment with dependency injection and caching mechanisms. Finally, take some time to learn about unit testing best practices and apply them to your existing codebase. With dedication and persistence, you’ll become a master SPFx developer in no time.

Worse even, there are developments re: #cheating which involve using "#AI" to merely #aimbot / a player into making hits, including stochastic delays and inaccuracy to hide it.

This doesn't even account for the fact that #Linux isn't a good platform to do these #malware-style #Kernelhack|s but also that trying to do #ClientSide #Anticheat isn't worth the hassle.

  • Which is why Valve works hard on "AI"-based #cheat detection in a way #fraud with #CreditCard|s is being combatted through #plausibility checks and per-transaction risk assessment.

The whole #CSGO / #CS2 "#Overwatch" basically amounts to #training (alongside with the existing footage of "known good" and "known bad" examples) of those "AI" efforts!

  • Simply because with every gameplay they are able to collect metrics and will automatically flag games if someone were to suddenly have an extremely good K/D.

This is also why #Ranking is enforced in #Competitive #Multiplayer of #CounterStrike2 and why Valve yeeted "#smurf"-accounts because #smurfing taints their dataset.
