Webpack docs: what does `api` refer to?

[chriscalo]

On the Webpack configuration page, it says the following:

In api.chainWebpack and api.configureWebpack, you have access to some environment variables:

• process.env.VUE_CLI_SSR_TARGET: Either 'client' or 'server'
• process.env.VUE_CLI_MODE: Vue CLI mode

What does api refer to? Is it possible to provide a complete example that shows where the api variable comes from?

I think I figured it out and proposed a docs change in #142.
