### [`v0.13.3`](https://togithub.com/evanw/esbuild/blob/master/CHANGELOG.md#0133)
[Compare Source](https://togithub.com/evanw/esbuild/compare/v0.13.2...v0.13.3)
- Support TypeScript type-only import/export specifiers ([#1637](https://togithub.com/evanw/esbuild/pull/1637))
This release adds support for a new TypeScript syntax feature in the upcoming version 4.5 of TypeScript. This feature lets you prefix individual imports and exports with the `type` keyword to indicate that they are types instead of values. This helps tools such as esbuild omit them from your source code, and is necessary because esbuild compiles files one-at-a-time and doesn't know at parse time which imports/exports are types and which are values. The new syntax looks like this:
```ts
// Input TypeScript code
import { type Foo } from 'foo'
export { type Bar }
// Output JavaScript code (requires "importsNotUsedAsValues": "preserve" in "tsconfig.json")
import {} from "foo";
export {};
```
See [microsoft/TypeScript#45998](https://togithub.com/microsoft/TypeScript/pull/45998) for full details. From what I understand this is a purely ergonomic improvement since this was already previously possible using a type-only import/export statements like this:
```ts
// Input TypeScript code
import type { Foo } from 'foo'
export type { Bar }
import 'foo'
export {}
// Output JavaScript code (requires "importsNotUsedAsValues": "preserve" in "tsconfig.json")
import "foo";
export {};
```
