## Bundling
|
|
|
|
`deno bundle [URL]` will output a single JavaScript file, which includes all
|
|
dependencies of the specified input. For example:
|
|
|
|
```
|
|
> deno bundle https://deno.land/std/examples/colors.ts colors.bundle.js
|
|
Bundling "colors.bundle.js"
|
|
Emitting bundle to "colors.bundle.js"
|
|
9.2 kB emitted.
|
|
```
|
|
|
|
If you omit the out file, the bundle will be sent to `stdout`.
|
|
|
|
The bundle can just be run as any other module in Deno would:
|
|
|
|
```
|
|
deno run colors.bundle.js
|
|
```
|
|
|
|
The output is a self contained ES Module, where any exports from the main module
|
|
supplied on the command line will be available. For example, if the main module
|
|
looked something like this:
|
|
|
|
```ts
|
|
export { foo } from "./foo.js";
|
|
|
|
export const bar = "bar";
|
|
```
|
|
|
|
It could be imported like this:
|
|
|
|
```ts
|
|
import { foo, bar } from "./lib.bundle.js";
|
|
```
|
|
|
|
Bundles can also be loaded in the web browser. The bundle is a self-contained ES
|
|
module, and so the attribute of `type` must be set to `"module"`. For example:
|
|
|
|
```html
|
|
<script type="module" src="website.bundle.js"></script>
|
|
```
|
|
|
|
Or you could import it into another ES module to consume:
|
|
|
|
```html
|
|
<script type="module">
|
|
import * as website from "website.bundle.js";
|
|
</script>
|
|
```
