Remote Canvas

An adapter for Browser-based canvas implementations into a Rust application at scale.

Goals

• Provide a scalable way to use a browser-based Canvas implementation in Rust applications.
• Take advantage of multiple browsers at the same time
• Provide a nearly-identical API to 2D context rendering.

Future Goals

• Provide a nearly-identical API to WebGL context rendering.
• Integrate with local Chrome install or a Docker cluster of Chrome containers in order to provide a connected browser on demand.

Limitations

• A browser may disappear at any time which will destroy all attached Canvas' at the API level. It is up to the end user to restart their context.
  • This is intentional as, while tracking the context transactionally to restart it is relatively easy, it may have significant performance issues.
• Unless load is sufficiently high, only one browser will be used.
  • This is due to the use of async_std's MPMC channel versus a proper load balancing solution.
  • A long term solution may be a load balance job.
• No browser authentication
