# Download Progress
|
||
|
|
|
||
|
|
This example demonstrates how to download a file from a URL and show its
|
||
|
|
progress with a [Progress Bubble][progress].
|
||
|
|
|
||
|
|
In this case we're getting download progress with an [`io.TeeReader`][tee] and
|
||
|
|
sending progress `Msg`s to the `Program` with `Program.Send()`.
|
||
|
|
|
||
|
|
## How to Run
|
||
|
|
|
||
|
|
Build the application with `go build .`, then run with a `--url` argument
|
||
|
|
specifying the URL of the file to download. For example:
|
||
|
|
|
||
|
|
```
|
||
|
|
./download-progress --url="https://download.blender.org/demo/color_vortex.blend"
|
||
|
|
```
|
||
|
|
|
||
|
|
Note that in this example a TUI will not be shown for URLs that do not respond
|
||
|
|
with a ContentLength header.
