go-update

Brave component update server written in Go

go-update implements a component update server for use in brave-core written in Go.

The intended audience for this server is all users of brave-core.

The server is only intended to support a small number of extensions that Brave handles ourselves.

The component update server supports 2 types of requests both at the same endpoint /extensions

1. The POST /extensions endpoint uses an XML schema for the request and the response. Samples can be found in the tests.
2. The GET /extensions endpoint uses URL query parameters and responds with a similar XML schema. Samples can also be found in the tests.

This server is compatible with Google's component update server, so it is a drop-in replacement to handle the requests coming from Chromium.

When there is only a single extension requested, and if we do not support the extension ourselves, we will redirect the request to Google's component updater to handle the request.

This server also serves as a filter so Brave can blacklist any extension before it has a chance to redirect to Google's component updater.
