The dependency react-scripts was updated from 3.1.0 to 3.3.0.
This version is not covered by your current version range.
If you don’t accept this pull request, your project will work just like it did before. However, you might be missing out on a bunch of new features, fixes and/or performance improvements from the dependency update.
v3.3.0 is a minor release that adds new features, including custom templates and support for the new optional chaining and nullish coalescing operators.
Custom Templates
You can now create a new app using custom templates.
We've published our existing templates as cra-template and cra-template-typescript, but we expect to see many great templates from the community over the coming weeks.
The below command shows how you can create a new app with cra-template-typescript.
npx create-react-app my-app --template typescript
Note that you can omit the prefix cra-template- when specifying which template you would like. For TypeScript users, we're deprecating --typescript in favour of --template typescript.
If you don't set a template, we'll create your new app with cra-template - which is just a new name for our base template.
Optional Chaining and Nullish Coalescing Operators
// Optional chaining
a?.(); // undefined if `a` is null/undefined
b?.c; // undefined if `b` is null/undefined// Nullish coalescingundefined??'some other default'; // result: 'some other default'null??'some other default'; // result: 'some other default'''??'some other default'; // result: ''0??300; // result: 0false??true; // result: false
If your're using TypeScript, you will need to upgrade your typescript dependency to 3.7.0 or later if you wish to use the new operators.
If you're using Visual Studio Code 1.40 (the latest as of this release) or earlier, you will need to configure your editor if you want it to understand the new operators.
We've added support for numeric separators to improve readability of numeric literals.
