Externalized Libraries

1fe supports webpack externals via the 1fe/cli. This allows widgets to exclude common libraries from output bundles.

Why Externalize Libraries?

We can reduce widget bundle sizes and improve app load time (ALT) by sharing commonly used libraries at the 1fe shell level, aka “externalizing” them.

How are libraries externalized within 1fe?

Via webpack externals, 1fe/cli will automatically externalize libraries that are configured to be externalized within your hosted live configurations.

The version string you see in a widget’s package.json is an illusion of control. At runtime, when the widget is rendered by the 1fe shell, the 1fe/shell will load the version specified version within the live configurations instead.
