Usage Examples

Default Options

In this example, the default options are used to do build target all in the level bem-project. BEM is installed as a global package.

grunt.initConfig({
    bem: {
        all: {
            root: 'bem-project'
        }
    }
})

Custom Options

In this example, custom options are used to do build targets desktop.bundles and touch.bundles. BEM is installed as a local package.

grunt.initConfig({
    bem: {
        options: {
            require: 'bem-project/node_modules/bem',
            root: 'bem-project'
        },
        'desktop.bundles touch.bundles': {
            verbosity: 'warn'
        },
    }
})

Advanced Example

grunt.initConfig({
    watch: {
        bem: {
            files: ['bem-project/*.bundles/*/*.bemjson.js'],
            tasks: ['bem:bundles'],
            options: {
                interrupt: true
            }
        }
    },
    bem: {
        options: {
            require: 'bem-project/node_modules/bem',
            root: 'bem-project',
            verbosity: 'warn'
        },
        'bundles': {
            targets: 'desktop.bundles touch.bundles'
        },
        'bundles-forced': {
            targets: 'desktop.bundles touch.bundles',
            forced: true
        }
    }
});

grunt.registerTask('default', ['bem:bundles-forced']);
