SharePoint Framework v1.8.0 release notes

We'll release more updated documentation and guidance videos during upcoming days and weeks. Your feedback on needed assets and topics is more than welcome.

Released: March 14, 2019

Upgrading projects from v1.7.1 to v1.8.0

  1. In the project's package.json file, identify all SPFx v1.7.1 packages. For each SPFx package:

    1. Uninstall the existing v1.7.1 package:

      npm uninstall @microsoft/{spfx-package-name}@1.7.1
      
    2. Install the refreshed v1.8.0 package:

      npm install @microsoft/{spfx-package-name}@1.8.0.0 --save --save-exact
      
  2. Make sure that there's an entry in the devDependency section of package.json that references "@microsoft/sp-tslint-rules": "1.8.0".

  3. Add a @microsoft/rush-stack-compiler-x-x package as a devDependency in the package.json. Refer to the section Support for TypeScript 2.7, 2.9 and 3.x (General Availability) for details on the correct version to use.

  4. Update your tsconfig.json file to extend the TypeScript configuration for your version of the @microsoft/rush-stack-compiler-x-x. Do this by modifying the top of the file as follows:

    • For @microsoft/rush-stack-compiler-2-7, the top of the tsconfig.json file would look like

      {
         "extends": "./node_modules/@microsoft/rush-stack-compiler-2.7/includes/tsconfig-web.json",
         "compilerOptions": { // ommitted for brevity }
      }
      
    • For @microsoft/rush-stack-compiler-3-3, the top of the tsconfig.json file would look like

      {
         "extends": "./node_modules/@microsoft/rush-stack-compiler-3.3/includes/tsconfig-web.json",
         "compilerOptions": { // ommitted for brevity }
      }
      
  5. Fix all the new and interesting tslint errors that are now getting raised with a newer compiler. For large projects, this might take a while. The default behavior of the TypeScript compilers is getting stricter, but your code will be the better for it.

Tip

The CLI for Microsoft 365 provides an easy step-by-step guidance to upgrade your solutions to latest SharePoint Framework version.

Note

The CLI for Microsoft 365 is an open-source solution with active community providing support for it. There is no SLA for the open-source tool support from Microsoft.

New features and capabilities

SPFx development for Teams tabs (General Availability)

Teams Tabs solutions using SPFx is now fully supported. Add TeamsTab to the supportedHosts property in the web part manifest and deploy it to the app catalog. From there, you can choose the solution and click the "Sync to Teams" button. The web part will now appear as an app in teams. When a web part is hosted in a Teams Tab, it will have access to the Teams SDK via the web part context. There are the following changes from the beta release in 1.7:

  • Initial and future configurations are handled using the Property Pane
  • The manifest property canUpdateConfiguration can be set to false to disable configuration after the initial configuration
  • Reduced JavaScript overhead to host the web part
  • “Sync to Teams” feature to automate Teams manifest creation and upload
  • Update teams-js to v1.4.1
  • Locale is driven by the current Teams Locale

App Pages (General Availability)

We frequently receive requests to have a single-page-app framework in SPFx. We hope App Pages will meet the majority of the goals around SPAs while providing a similar development model and user experience. App pages are a new SharePoint modern page layout, which hosts a single web part on the entire page; keeping the look and feel (navigation, header, theme, and so on) consistent. Adding SharePointFullPage to the supportedHosts property of the web part manifest will add an App Page with the web part option when creating a new page.

The web part can be configured (unless the canUpdateConfiguration property is false), but the page layout/content can't be modified. The end-user creation of app pages should be rolling out later this month with the new page creation experience. In the meantime, there's a static page (located at _layouts/15/appPageHost.aspx?componentId=yourComponentGuidHere) that will host any component in an app page. This page is rolling out now and should be available at release time, or a day or two later, depending on your tenant.

Domain isolated web parts (General Availability)

SPFx components running inside the current page is simple and fast. However, there are scenarios where a stronger level of isolation is wanted. Domain isolated web parts run in an iframe with a separate domain, which can have different permissions from the host page. This allows, for example, a web part to access the current user’s email without giving all code running in the tenant the same level of access.

The domain and its AAD app are created and managed for the tenant - the tenant admin will need to approve the permissions requested by the solution. For end users, the web part looks and behaves like any other web part. At this time, domain isolated web parts only support Dynamic Data in the Page Context. Full part-to-part communication will come in a future update.

Library Components (Developer Preview)

You can now create libraries that other SPFx components can reference. They're a bit tricky to use, so we'll be publishing a separate document that describes them in more detail. The trick is that you need to publish your library to an npm feed (internal is fine) to consume it.

Support for TypeScript 2.7, 2.9 and 3.x (General Availability)

In this release, we've done work to separate out the version of TypeScript from the version of SPFx you're using. You can now specify the version of TypeScript you want to use separate from the build system itself. You can use any compiler listed here: https://www.npmjs.com/search?q=%40microsoft%2Frush-stack-compiler.

Note

The compiler you use needs to be reflected in your tsconfig.json file, with a reference to "extends": "./node_modules/@microsoft/rush-stack-compiler-2.7/includes/tsconfig-web.json", that matches the version of the rush-stack-compiler you include.

We noticed at the last moment that some of the recent versions of the @microsoft/rush-stack-compiler packages aren't working correctly. If you find that the npm install gives warnings about peer dependencies for TypeScript, and the build fails with complaints of not finding a compiler, use an earlier version of the package.

The following versions of the @microsoft/rush-stack-compiler should be used with the corresponding TypeScript version.

  • TypeScript v2.7
    • @microsoft/rush-stack-compiler-2.7@0.5.7
  • TypeScript v2.9
    • @microsoft/rush-stack-compiler-2.9@0.6.8
  • TypeScript v3.0
    • @microsoft/rush-stack-compiler-3.0@0.5.9
  • TypeScript v3.3
    • @microsoft/rush-stack-compiler-3.3@0.1.6

Web part variant theming in SharePoint modern pages

SharePoint modern pages recently released a feature to have section background colors. Web parts can update their theming to reflect the background color the web part is rendering over. Setting the supportsThemeVariants property in the web part manifest to true will disable the default behavior of always rendering a white background.

Web parts can then use the SPFx ThemeProvider to be notified of background color changes.

Changes in this release

Removed PropertyPane code out of @microsoft/sp-webpart-base

We're moving the property pane code to a different package (@microsoft/sp-property-pane) that contains all the property pane logic that previously existed in @microsoft/sp-webpart-base. Solutions that are currently running will continue to work (we'll forward the calls appropriately), but the public property pane APIs on the @microsoft/sp-webpart-base are deprecated in SPFx v1.8, and will be removed in the SPFx v1.9 release.

Your code changes simple needs to change the imported package. They have the exact same types and signatures; they're located in a different package. This allows us to only load the property pane code (and all its dependent packages) only when needed.

Deprecations and removed items in this release

Legacy Fabric CSS consumption

Since release of SPFx v1.0, we've added a bunch of Fabric CSS to the page. Although we've changed how Fabric CSS works since then, we continued adding the old version of Fabric CSS to the page. This wound up adding a considerable about of unneeded CSS. Starting with SPFx 1.8.0, solutions will no longer load the old Fabric CSS.

If your solution still needs the pre-1.8.0 behavior, add ”loadLegacyFabricCss”: true to your component manifest.

If your styles aren't working correctly after upgrading to 1.8.0, you might need to switch this setting.

Instead, your solution can import the Fabric.css stylesheet like so:

import 'office-ui-fabric-react/dist/css/fabric.css';

Known issues and limitations

The new end-user experience to create app pages is dependent on the new Add a Page experience in modern pages. This is being rolled out now but release in your tenant may be a few days behind.

As mentioned in the TypeScript support section, some of the more recent builds of the @microsoft/rush-stack-compiler that we use are having problems. The earlier versions work. We'll publish updates and notifications when this is addressed.

The updated provider hosted model for hosting Microsoft Teams solutions in SharePoint Online (using the Teams SDK) is still in preview.

Dynamic data support for isolated domain parts is limited to the page context data source. Full support for dynamic data across the iFrame boundary will come in a future update.
