The same is true for text editors like Sublime Text and Atom, which - although they have plugins that allow for rudimentary syntax highlighting and code checking - don’t have the context knowledge of the Javascript code you are writing, let alone check for syntax errors, unused variables/functions, type checking, and function signature mismatches, to name just a few. If you have any questions or feedback, please don’t hesitate to post them in the comments below.Although SAP provides pretty useful Eclipse plugins for SAPUI5 / OpenUI5 development, it still doesn’t help you write better, efficient, correct code. To do so, look for Schematics using the Find Action popup ( Cmd/Ctrl-Shift-A) or select Angular Schematic… from File | New in the main menu: You can do this in the file of a specific library by adding enableIvy: false under angularCompilerOptions as shown below:įinally, you can use schematics with Angular 9 just like you could in the previous framework versions. So, if you use any of the mentioned constructs in your local library, we recommend switching Ivy off for it. While this information is not required by the Ivy compiler, it is needed for the IDE to provide you with completion suggestions and code inspections. However, this metadata lacks information about some code constructs, such as annotations or ng-content selectors. To get code completion for them, you need to enable Ivy metadata support. If your project uses local libraries created with ng generate library, in Angular 9 they are set to compile with Ivy by default. Voila! Support for Ivy metadata has now been enabled. Tick an empty box next to this key and restart the IDE in order for the change to take effect: Start typing angular.enableIvyMetadataSupport, and you’ll see the corresponding registry key. Let’s see how you can turn Ivy metadata support on in WebStorm for even faster code insight. First, press Cmd/Ctrl-Shift-A, type Registry in the Find Action popup and select it from the search results: This is likely to change later depending on user feedback, our own testing results, and changes on the Angular side. However, as some of the parts of the new standard are still being polished, we don’t have it enabled by default for now. Thanks to this new approach, WebStorm can provide you with even faster code completion and inspection results. Enabling Ivy metadata support in WebStormĪngular 9 brings a new approach of defining additional metadata in. If you’d like to update an existing project to version 9, the best option is to do so by following the detailed instructions from the official Angular website. And, of course, you can get all the benefits provided by the Ivy compiler, such as faster compilation, smaller bundle size, and improved type checking, to name but a few. However, there’s one exception, local libraries, which we’ll cover in a second. In an Angular 9 project, you can use the features you’d typically expect when working with Angular in WebStorm, such as code completion and auto imports in TypeScript and template files, all available and requiring no configuration. With npx selected, WebStorm will generate a new Angular 9 project with all the required configuration files and dependencies as soon as you click Create: When creating a new Angular project, WebStorm will use the Angular CLI installed globally on your machine or get its latest version via npx: The fastest way to create a new Angular 9 project is to click Create New Project on the welcome screen and select Angular CLI from the list of available projects. Creating a new project and updating to version 9 To help you work with Ivy and other Angular 9 features, we’ve added support for them to WebStorm. See this blog post for more information.Ī long-awaited update of the Angular framework, Angular 9, was finally released last week! If you’ve closely followed the news about this update, you might already know that it comes with a number of great enhancements, with the most exciting of them being the new default compiler and runtime, Ivy. Note: In WebStorm 2020.1 onwards, support for the Ivy metadata is enabled by default. Enabling Ivy metadata support in WebStorm.Creating a new project and updating to version 9.
