funcName

Name carefully. If function name already exists in yaml file your function will be overwritten.

➜ sls-fgen --funcName=hello

➜ sls-fgen -n hello

funcPath

File path + name of the function that is going to be written to the file.

➜ sls-fgen --funcPath=handler.hello

➜ sls-fgen -p handler.hello

If our language is JavaScript, CLI is going to create handler.js file within a function named hello.

You can also specify a folder. This tool cannot create folder. So the folder you are passing should already be existing.

➜ sls-fgen --funcPath=someFolder/handler.hello

➜ sls-fgen --method=get

➜ sls-fgen -m get

httpPath

➜ sls-fgen --httpPath=user

➜ sls-fgen -h user

yamlPath

➜ sls-fgen --yamlPath=serverless.yml

➜ sls-fgen -y serverless.yml

Customize

Open template file related to language or edit defaults.

You can open template files with these commands. Visual Studio Code must be installed for this operation.

➜ sls-fgen --edit=defaults

➜ sls-fgen --edit=js

➜ sls-fgen -e js

const templates = {
  default: (name) => {
    return `module.exports.${name} = async (event) => {}`;
  },

  otherTemplate: (name) => {
    return `module.exports.${name} = async (event) => {}`;
  },
};

You can also add new languages by creating it's folder. Checkout templates folder.
