MoocJS

moocjs is a Docker container that runs node.js, it contains the npm modules needed by the exercises proposed in the "Diffuse JavaScript" MOOC.

Building MoocJS

If you want to rebuild that container, the sources are held on GitHub. The container itself is stored on Docker Hub under name paracamplus/moocjs.

Running MoocJS

There is more than one way to run the moocjs Docker container. The next command will run the container in the current directory where it starts an interactive Read-Eval-Print loop:

docker run --rm -it -v $(pwd):/usr/src/app paracamplus/moocjs -p -i

The --rm flag will remove the container after exit. The -it flag tells Docker to run interactively. The -v $(pwd):/usr/src/app mounts the current directory in the current directory of the container where node will be run.

Options -p and -i are for Node.js, -i starts the REP loop, -p prints the results.

Here are some example using other options:

docker run --rm -v $(pwd):/usr/src/app paracamplus/moocjs jasmine
docker run --rm -v $(pwd):/usr/src/app paracamplus/moocjs jasmine spec/test1-spec.js

This command will run jasmine on all tests of the current spec/ sub-directory. The second command run jasmine on a single test file.

docker run --rm paracamplus/moocjs npm ls

This command will list all installed packages and their dependencies.

docker run --rm paracamplus/moocjs bash

This command will start a bash interpreter in the /usr/src/app/ empty directory within the container. It allows to explore the content of the Docker container.

And finally

docker run --rm paracamplus/moocjs -h

To print the usage documentation of the container.
