Question: How do you update the metadata from caniuse.com

First, you have to install coffee-script locally:

$ npm install coffee-script

Then you can use this command (from your project root)

$ node_modules/grunt-autoprefixer/node_modules/.bin/autoprefixer --update

Also you can create symlink and use short autoprefixer command:

$ ln -s ../grunt-autoprefixer/node_modules/.bin/autoprefixer node_modules/.bin/autoprefixer
$ autoprefixer --version           
autoprefixer 0.8.20131029

I'm going to add the symlink creation as postinstall script or move autoprefixer in peer dependencies, so this shorthand will work out of the box.

I used grunt-shell and just made a task to run the update command before starting the server, and before building.

[mrbinky3000]

    grunt.registerTask("updateprefixes", [
        "shell:updateprefixes"
    ]);

        shell: {
            updateprefixes: {
                options: {
                    stdout: true,
                    execOptions: {
                        cwd: "node_modules/grunt-autoprefixer/node_modules/.bin"
                    }
                },
                command: "autoprefixer --update"
            }
        }

BTW, I highly not recomment to use autoprefixer --update. Just update autoprefixer npm package, it always contain latest data from Can I Use.

For example, if you update by --update you will not get support for new properties and bug fixes.

In packages update by autoprefixer --update should be used only in some very big companies, which can update libraries too often.

@ai, thanks for making this clear. Anyway, having the shorthand may be useful in some cases.
