    2.0.0-alpha.14 • Public • Published

    NPM version

    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.

    You will also need to change require('canvas') to require('canvas-prebuilt').

    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

    Linux technicalities

    Linux users will need glibc >= 2.13.1 (Ubuntu 14.04+, Debian 7+, etc)

    If you are using fonts, you might see some FontConfig warnings which are harmless:

    Situation Message Meaning
    You have an old version of FontConfig on your system Fontconfig warning: line 142: blank doesn't take any effect anymore. please remove it from your fonts.conf You don't need to do anything, but removing said line or upgrading FontConfig on your system should fix it
    You don't have FontConfig Fontconfig error: Cannot load default config file You don't have any fonts on your system, so if you want to use the text APIs you'll either need to install FontConfig or use Canvas.registerFont


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


    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


    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


    npm i canvas-prebuilt
