This is COPPA

> Lightweight CLI tool for local developement of serverless Google Cloud Functions

Coppa was made for developers working with google cloud serverless functions. Coppa creates a local dev server that mimicks deployed cloud functions.

Coppa is different from Google Cloud Functions NodeJS Emulator because it does not require devs to deploy each function locally. Coppa just reads your yaml file and your main index file and spins up a quick dev server for easy and painless debugging and development.

Coppa even provides a free documentation page auto generated based on your functions, by leveraging the npm package quantor.

Install

This is a CLI tool so it's best to install globally for convenience.

Yarn:

``sh
yarn global add coppa
`

NPM:

`sh
npm i -g coppa
`

Usage

cd into your app directory that contains your serverless.yml file and your main index.js file that holds all your cloud functions, then run:

`sh
coppa start
`

This command will start the dev server using the default arguments for locating files, which is ./serverless.yml for the serverless yaml, and ./index.js for the main entry point.

These can be changed by passing in flags to Coppa. To see all the flags, run:

`sh
coppa start --help
`

To use any flag, include it in the command:

`sh
coppa start -c path/to/serverless.yml -p 9001
`

Hot reloading with nodemon

`sh
nodemon --exec coppa start
`

Flags

Here are all the available flags for the start command.

- -c, --config [path] Path to serverless config file (default: ./serverless.yml)
- -e, --entry [path] Path to JS entry point file (default: ./index.js)
- -s, --stage [stage] Stage to be used
- -p, --port [port]` Port for server to use (default: 8080)
