### [`v3.3.0`](https://togithub.com/facebook/create-react-app/blob/master/CHANGELOG.md#330-2019-12-04)
[Compare Source](https://togithub.com/facebook/create-react-app/compare/v3.2.0...v3.3.0)
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`](https://togithub.com/facebook/create-react-app/tree/master/packages/cra-template) and [`cra-template-typescript`](https://togithub.com/facebook/create-react-app/tree/master/packages/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`.
```sh
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
We now support the [optional chaining](https://togithub.com/TC39/proposal-optional-chaining) and [nullish coalescing](https://togithub.com/tc39/proposal-nullish-coalescing) operators!
```js
// Optional chaining
a?.(); // undefined if `a` is null/undefined
b?.c; // undefined if `b` is null/undefined
// Nullish coalescing
undefined ?? 'some other default'; // result: 'some other default'
null ?? 'some other default'; // result: 'some other default'
'' ?? 'some other default'; // result: ''
0 ?? 300; // result: 0
false ?? true; // result: false
```
**If you'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.**
If you're using TypeScript in your project and have already upgrade its version as described above, then you can [configure VS Code to `Use Workspace Version` of TypeScript](https://code.visualstudio.com/docs/typescript/typescript-compiling#_using-newer-typescript-versions). If your project isn't using TypeScript, you can use the [JavaScript and TypeScript Nightly extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode.vscode-typescript-next) until VS Code releases a newer version including TypeScript `3.7.0` or newer.
##### Numeric Separators
We've added support for [numeric separators](https://togithub.com/tc39/proposal-numeric-separator) to improve readability of numeric literals.
```js
1000000000; // Is this a billion? a hundred millions? Ten millions?
101475938.38; // what scale is this? what power of 10?
1_000_000_000; // Ah, so a billion
101_475_938.38; // And this is hundreds of millions
```
##### no-unexpected-multiline
We've removed this rule as it is not compatible with Prettier. If you rely on this rule you can re-enable it by [extending our ESLint config](https://create-react-app.dev/docs/setting-up-your-editor/#experimental-extending-the-eslint-config) and adding the following:
```json
{
"extends": "react-app",
"rules": {
"no-unexpected-multiline": "warn"
}
}
```

If your project isn't using TypeScript, you can use the [JavaScript and TypeScript Nightly extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode.vscode-typescript-next) until VS Code releases a newer version including TypeScript `3.7.0` or newer. ##### Numeric Separators We've added support for [numeric separators](https://togithub.com/tc39/proposal-numeric-separator) to improve readability of numeric literals. ```js 1000000000; // Is this a billion? a hundred millions? Ten millions? 101475938.38; // what scale is this? what power of 10? 1_000_000_000; // Ah, so a billion 101_475_938.38; // And this is hundreds of millions ``` ##### no-unexpected-multiline We've removed this rule as it is not compatible with Prettier. If you rely on this rule you can re-enable it by [extending our ESLint config](https://create-react-app.dev/docs/setting-up-your-editor/#experimental-extending-the-eslint-config) and adding the following: ```json { "extends": "react-app", "rules": { "no-unexpected-multiline": "warn" } } ``` ##### :rocket: New Feature - `babel-preset-react-app` - [#7438](https://togithub.com/facebook/create-react-app/pull/7438) Add optional chaining and nullish coalescing operators support ([@renatoagds](https://togithub.com/renatoagds)) - `babel-preset-react-app`, `react-dev-utils` - [#7817](https://togithub.com/facebook/create-react-app/pull/7817) Add numeric separator support ([@tharun208](https://togithub.com/tharun208)) - `cra-template-typescript`, `cra-template`, `create-react-app`, `react-scripts` - [#7716](https://togithub.com/facebook/create-react-app/pull/7716) Add template support ([@mrmckeb](https://togithub.com/mrmckeb)) ##### :boom: Breaking Change - `create-react-app`, `react-dev-utils`, `react-scripts` - [#7988](https://togithub.com/facebook/create-react-app/pull/7988) Bump webpack-dev-server ([@ianschmitz](https://togithub.com/ianschmitz)) **NOTE: This is only a breaking change if you're using `react-dev-utils` outside of Create React App.** ##### :bug: Bug Fix - `eslint-config-react-app` - [#8039](https://togithub.com/facebook/create-react-app/pull/8039) Remove no-unexpected-multiline rule ([@iansu](https://togithub.com/iansu)) - `create-react-app` - [#7991](https://togithub.com/facebook/create-react-app/pull/7991) Support templates in scoped packages ([@klasbj](https://togithub.com/klasbj)) - [#7839](https://togithub.com/facebook/create-react-app/pull/7839) added check for typescript template and unsupported node version ([@awaseem](https://togithub.com/awaseem)) - `react-scripts` - [#7860](https://togithub.com/facebook/create-react-app/pull/7860) Mark TypeScript as an optional peer dependency for react-scripts ([@dstaley](https://togithub.com/dstaley)) - [#7822](https://togithub.com/facebook/create-react-app/pull/7822) Fix absolute paths issue in Jest ([@rovansteen](https://togithub.com/rovansteen)) - [#7796](https://togithub.com/facebook/create-react-app/pull/7796) Fixed process type in TypeScript template.
