In this post I’ll reference what I consider to be the most interesting and hot topics on the React community… and try to make it short.

If you haven’t seen the conference, you can take a look at this YT playlist for all sessions.

The state of React 2022

So first of all, what is the state of React currently? With React 18, what was once called concurrent mode is now concurrent features. This changes the approach into an incremental adoption, so that you could use concurrent features in specific places of your React app.

In this talk, Lee also announces Next.js new routing system which resembles Remix a lot. They want to take advantage of nested routes which is great! This allows us to provide a better user experience on pages that have one component that blocks rendering.

Last but not least, there are new developments when it comes to server-side rendering, and new client-side rendering APIs.

Edge computing

If you are unaware of this type of compute, Edge computing allows a better user experience, because it reduces the time you get a response with the content you want to visualize. The time is reduced because to process your request you don’t need to “talk” to a distant server on the oasis.

CDN providers like Cloudflare, are building new runtimes to allow you to run code closer to your customers – on the edge. Cloudflare workers for example, don’t use Node.js or Deno under the hood, it’s their own JS runtime. Of course, an effort is being done to standardize these runtimes.

In this talk, Kent talks about how Remix improves the developer experience for edge computing. First they use the Web Fetch API, and depending on where you want to deploy your function. Remix then translates the request/response objects to the respective platform’s API. They also support streaming in the edge, in order to send some content to the user quickly, and then send the rest.

With that said, this is all in JS/TS or WASM land. At least I haven’t seen a lot of support for other languages and runtimes (e.g. C#) on services that provide edge computing.

Streaming server components

With React 18 it’s now possible to stream changes to the browser, with new APIs like Suspense that allows for asynchronous processing.

Why is this cool? Because we don’t want to block rendering with data fetching. When our component needs to fetch data before rendering what the user wants to see, we need to render a loading spinner… which ain’t cool.

How about we initiate fetches before we render. This way the requests are in parallel and don’t block rendering. Using streaming server rendering fixes this, which is why it’s so awesome! Ryan Florence goes more in detail how this is done in this talk: When to fetch: Remixing React Router.

Bear in mind, this is just one way of rendering. Last year at React Conf 2021 there was an intro session about this topic as well: Streaming Server Rendering with Suspense. Another great session that talks about the different rendering patterns: Advanced Rendering Patterns: Lydia Hallie. It’s an amazing session to help you visualize the impacts on performance, and what are the trade-offs of each pattern.

Are you new to SharePoint or do you just want to learn how to develop SharePoint modern solutions? Then, you came to the right place!

This is a guide to help you learn SharePoint Framework (SPFx), a framework to develop SharePoint (and Teams) client-side solutions. SPFx leverages the following technologies:

• React / Angular
• TypeScript
• SharePoint Online
• Microsoft Teams

The Basics

SharePoint Framework is a page and web part model that provides full support for client-side SharePoint development, easy integration with SharePoint data, and extending Microsoft Teams. With the SharePoint Framework, you can use modern web technologies and tools in your preferred development environment to build productive experiences and apps that are responsive and mobile-ready.

The SPFx is the recommended SharePoint customization and extensibility model for developers. Due to tight integration between SharePoint Online, Microsoft Teams, and Microsoft Viva Connections, developers can also use SPFx to customize and extend all these products. In fact, SPFx is the only extensibility and customization option for Viva Connections.

In addition to SharePoint Online, SPFx is supported and can be used to customize SharePoint on-premises deployments going back to SharePoint Server 2016.

With the SharePoint Framework, we can develop:

• Web Parts
• Extensions
• Library components
• Adaptive Card Extensions

Technology stack

SPFx Development Toolchain

TypeScript

TypeScript is the preferred programming language to develop in SPFx. TypeScript is a programming language and maintained by Microsoft and is a superset of JavaScript and adds optional static typing to the language to develop client-side solutions. It is designed for the development of large applications and transpiles to JavaScript to be executed in the browser.

Useful TypeScript concepts:

• const – allows the definition of a variable whose value is not going to be changed. Use this instead of let if the variable value is not going to be changed after its declaration.
• let – allows the definition of a variable whose value is going to be changed. Use this instead of const if the variable value is going to be changed after its declaration.
• var – allows the definition of a variable whose value is going to be changed. To be avoided since variables declared with var are acessible from any scope (scope (function, module, namespace, global)
• type – allows the definition of a data class without any business logic or methods, just data. It can be also useful to avoid the usage of magic strings in the code.
• enum – allows the definition of a enumeration
• interface – allows the definition of a interface that can then be implemented by a concret class.
• class – allows the definition of a class that optionally implements an interface
• extends – when used, it allows a class to inherit from another class
• export – allows the export of functions, variables, interfaces and classes that can be imported with the import statement
• import – allows the import of functions, variables, interfaces and classes exported with the export statement

React

React is a JavaScript library for building user interfaces and is at the core of SPFx to build advanced applications.

• Declarative: React makes it painless to create interactive UIs. Design simple views for each state in your application and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable, simpler to understand, and easier to debug.
• Component-Based: Build encapsulated components that manage their state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep the state out of the DOM.
• Learn Once, Write Anywhere: We don’t make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React can also render on the server using Node and power mobile apps using React Native.

Concepts / Tooling

Core SPFx Concepts

• JavaScript frameworks
• Node.js
• NPM (Node Package Manager)
• Yeoman
• Gulp
• WebPack

NPM Packages

SharePoint client-side development tools use the npm package manager, like NuGet, to manage dependencies and other required JavaScript helpers. npm is typically included as part of Node.js setup.

Package installation modes:

• npm install @package – installs the package
• npm install @package –save – installs the package and updates package.json automatically (dependencies section)
• npm install @package@version –save-dev – installs the package and updates package.json automatically (devDependencies section)
• npm install @package@version –save – installs the package with the specified version and updates package.json automatically (dependencies section)
• npm install @package@version –save-dev – installs the package with the specified version and updates package.json automatically (devDependencies section)

Useful npm packages to include in a SPFx solution:

• npm install gulp yo @microsoft/generator-sharepoint@<spfx_version> –global
  • Example: npm install gulp yo @microsoft/generator-sharepoint@1.15.2 –global
• npm install @microsoft/microsoft-graph-types –save
• npm install @pnp/sp –save
• npm install @pnp/graph –save
• npm install @fluentui/react –save
• npm install @pnp/spfx-controls-react –save
• npm install @pnp/spfx-property-controls –save
• npm install localforage  –save
• npm install @luudjanssen/localforage-cache –save
• npm install spfx-fast-serve -g
• npm install -g pnpm

Gulp Commands

• gulp clean – cleans the solution. Cleans the dist and temp folders from the solution
• gulp trust-dev-cert – installs the development certificate
• gulp build – builds the solution, tranforms TypeScript into JavaScript
• gulp bundle – bundles the solution and minimizes CSS and JS (in debug mode)
• gulp bundle –ship – bundles the solution and minimizes CSS and JS for deployment in SharePoint in production mode (release mode)
• gulp package-solution – generates package (.sppkg file) but to run in debug mode
• gulp package-solution –ship – generates package (.sppkg file) to run in production mode
• gulp serve – launches SharePoint Workbench to test web parts in debug mode
• gulp serve –nobrowser – allows testing web parts in debug mode but without launching SharePoint Workbench

SPFx Development Environment

Setup Development Environment

To setup your development environment, run the following commands from the command prompt:

• npm install gulp-cli yo @microsoft/generator-sharepoint –global
• npm install webpack –global
• npm install –save-dev webpack
• gulp trust-dev-cert

Node Version Manager (nvm)

Node Version Manager (NVM) allows developers to install multiple versions of node. This can be useful when working with different SPFx versions that use different versions of Node.

To download NVM, click here.

Install Node using NVM

After installing NVM, to install a node version use the following command:

nvm install <node_version>. Example: nvm install 14.19.1

Switch between versions of Node

If you have multiple versions of Node, you can switch between them using the following command:

nvm use <node_version>. Example: nvm use 12.22.10

To have a full list of the installed node versions, run “nvm list”.

SPFx Fast Serve

If you have a big SPFx solution, gulp serve can take a lot of time, especially if you want to rapidly test your developments. SPFx Fast Serve is a command line utility, which modifies your SharePoint Framework solution, so that it runs continuous serve command as fast as possible. To know more, click here. 

Here is a comparison between gulp serve and SPFx Fast Serve (times depend on hardware, environment). The times listed below are “refresh” time (the time needed to compile your project when you change a file and start refreshing a page in a browser):

This is a must have for every SharePoint Framework Developer!

SPFx Quick Start

The most common development component in SPFx is the web part. To better understand how to create your first web part, read this article. In SPFx client-side web parts, we have the following components:

• Web part main component – acts as a container to the React component that has the main logic. In this example, we have a web part class called BirthdaysWorkAnniversariesNewCollaboratorsWebPart that renders the BirthdaysWorkAnniversariesNewCollaborators React component that has the web part main logic.

• React component associated with the web part. This file has a render method responsible for the rendering of the web part UI and uses two major React concepts: props supplied by the web part that allows users to configure the web part behavior and state that also allows to control how the the web part is rendered. The main difference between props and state is that state can be changed and props can’t (in the code they are readonly). In the example below, we have the BirthdaysWorkAnniversariesNewCollaborators React component that was called by the BirthdaysWorkAnniversariesNewCollaboratorsWebPart web part.

• Other associated files such as:
  • Service classes to get data from SharePoint or Microsoft Graph for instance
  • Data object classes (models)
  • Helper classes
  • etc
