Version 10 of Angular now available


Version 10.0.0 is here! This is a major release that spans the entire platform, including the framework, Angular Material, and the CLI. This release is smaller than typical; it has only been few months since we released version 9.0 of Angular.

We try to release two major versions each year to keep Angular synchronized with the rest of the JavaScript ecosystem and to have a predictable schedule. We plan to release version 11 this fall.

What’s in this release?

New Date Range Picker

Angular Material now includes a new date range picker.

To use the new date range picker, you can use the mat-date-range-input and mat-date-range-picker components.

Warnings about CommonJS imports

When you use a dependency that is packaged with CommonJS, it can result in larger slower applications.

Starting with version 10, we now warn you when your build pulls in one of these bundles. If you’ve started seeing these warnings for your dependencies, let your dependency know that you’d prefer an ECMAScript module (ESM) bundle.

Optional Stricter Settings

Version 10 offers a more strict project setup when you create a new workspace with ng new.

ng new --strict

Enabling this flag initializes your new project with a few new settings that improve maintainability, help you catch bugs ahead of time, and allow the CLI to perform advanced optimizations on your app. Specifically, the strict flag does the following:

  • Enables strict mode in TypeScript
  • Turns template type checking to Strict
  • Default bundle budgets have been reduced by ~75%
  • Configures linting rules to prevent declarations of type any
  • Configures your app as side-effect free to enable more advanced tree-shaking

Keeping Up to Date with the Ecosystem

As usual, we have made a few updates to the dependencies of Angular to stay synchronized with the JavaScript ecosystem.

  • TypeScript bumped to TypeScript 3.9
  • TSLib has been updated to v2.0
  • TSLint has been updated to v6

We’ve also updated our project layout. Starting with version 10 you will see a new tsconfig.base.json. This additional tsconfig.json file better supports the way that IDEs and build tooling resolve type and package configurations.

New Default Browser Configuration

We’ve updated the browser configuration for new projects to exclude older and less used browsers.

This has the side effect of disabling ES5 builds by default for new projects. To enable ES5 builds and differential loading for browsers that require it (such as IE or UC Browser), simply add the browsers you need to support in the .browserslistrc file.

Angular Team Fixit

We’ve dramatically increased our investment in working with the community. In the last three weeks our open issue count has decreased by over 700 issues across framework, tooling, and components. We’ve touched over 2,000 issues, and we plan to make large investments over the next few months, working with the community to do even more.

Deprecations and Removals

We’ve made several new deprecations and removals from Angular.

The Angular Package Format no longer includes ESM5 or FESM5 bundles, saving you 119MB of download and install time when running yarn or npm install for Angular packages and libraries. These formats are no longer needed as any downleveling to support ES5 is done at the end of the build process.

Based on heavy consultation with the community, we are deprecating support for older browsers including IE 9, 10, and Internet Explorer Mobile.
