CFA - Cloud Function Abstraction

CFA is a suite of tools to help you build cloud functions that run on any provider. It is designed to be a lighter alternative to Serverless and emphasize uniform development convention.

Currently under development.

cfa create <name>

Modules

The cfa cli tool runs on top of commander. You can create your own modules to implement new commands during development to enforce your own workflow for developers.

In custom modules, you need an entry point that exports the following:

module.exports = {

  //
  // Put in npm dependencies here.
  //

  dependencies: ["[email protected]"], 

  async onAdd() {

    //
    // Run code after adding this module for the first time
    //

    return;

  },

  onRun(program) {

    //
    // Run custom code on the CLI program to add your own commands
    //

    program
      .command("add-collection <collection>")
      .description("[cfa-mongo] Add collection <collection> to function")
      .action(addCollection);

  }

};
