Making Local Development Faster with Caches for NPM & Composer (Part One: NPM)

This is the first post in a two part series detailing how you can use Docker to run local caches of both remote NPM resources and composer packages.

docker pull keyvanfatehi/sinopia

After the image has been pulled down, you can run it and map to a port using the following syntax:

docker run -p 81:4873 keyvanfatehi/sinopia

This will run sinopia and bind the external interface to port 81. There is a fair few configuration options that you can specify, I’d recommend getting a copy of the configuration file then mounting that as a volume.

Next, at the top of the screen, it’ll give you the two commands to make your client version of NPM connect to your new shiny cache, it’ll be something similar to:

If you run those two commands, it’ll set your client to use your new cache and you’re good to go.
