canvas-prebuilt-yjy v1.6.5-prerelease.2

This is a drop-in replacement for canvas that does not require any compiling. To use it just npm install canvas-prebuilt or replace canvas with canvas-prebuilt in your dependencies.

The repo is just a set of scripts that downloads a specific node-canvas version, builds it and bundles it on all platforms. It's meant to run on Travis and AppVeyor but it can be run locally too

Releases

More detail on the releases below, this won't be relevant to most users.

Binaries

Make sure your node version is the most recent to guarantee ABI compatibility

¹I have some ideas on how to get these working with cross-compilation if people request it. I plan to add Linux/ARM

Canvas version mapping

I screwed up and had to unpublish a couple of versions so they aren't 1:1 with canvas. If you have the minor or major version fixed it should not matter.

Bundling

The bundling scripts just take a regularly compiled executable (canvas.node in this case) and look at which non-system libraries it links against. Those libraries are then copied to the release directory and binaries are updated if necessary to refer to them.

The strategies for bundling could be applied to other projects too since they're general:

• On macOS, macpack is used to search dependencies, filter out non-system ones, and update binary references
• On Windows, Dependency Walker's CLI is used to search dependencies. Anything in the MSYS2 folder is considered non-system. Patching is not necessary because Windows looks for dlls in the same folder as the binary
• On Linux, pax-utils searches dependencies, and everything not in /lib is non-system. The custom binding.gyp compiles canvas.node to look inside its own directory for dependencies
