The parts

• Dockerfile

• index.js

• Express.js docs

• OpenFaaS docs

Templates

With OpenFaaS Templates you don't need to bother with managing Dockerfiles and TCP-port bindings, unless you like that sort of thing, then you can do that too just like we did in this example.

• Microservice for Node.js with express visible
• Function for Node.js with express hidden
• Legacy Node template without express

Try one of the templates above with faas-cli template store ls/pull.
