LiveLambda

A libray for building backends using AWS Lambda.

Make Your Servers Serverless 🤓

Instructions

• liveLambda_v2.py and you <source_file> should be in same directory.
• Import LiveLambdaV2 class from liveLambda_v2.py file.

Example

from liveLambda_v2 import LiveLambdaV2

app = LiveLambdaV2()

# Route with a single method attached to it.

@app.route("/", "GET")
def getIndex():
  return {"page" : str(app.request), "route" : "GET /"}

@app.route("/", "POST")
def postIndex():
  return {"page" : str(app.request), "route" : "POST /"}

# Route with url parameters.

@app.route("/user/{id}", "POST")
def routeWithParam(id):
  return {"page" : str(app.request), "route" : "POST /user/{id}"}


# Route with multiple methods attached to it.

@app.route("/dynamic", ["GET", "POST", "PUT", "PATCH", "DELETE"])
def routeWithMultipleMethods():
  return {"key" : str(app.request), "route" : "GET /user"}

# Your source file must containe a method which lambda runtime will invoke.
# Name of function must be same in deployment config file.

def lambda_handler(event, context):
  response = app.run(event, context)
  return response

Deployment

Instructions

• Your source code must contain a config.json file which will contains deployment configuration and 'arn' of the role used by the AWS lambda to push the logs at AWS cloudwatch.

• Make a single .zip file containing liveLambda_v2.py, <your_source_code>.py, and all_libraries_you_use(files and folders) .

Sample config.json

{
  "file_path": "<path_to_zip_file>",
  "lambda_role_arn": "<arn>",
  "function_name": "<lambda_function_name>",
  "handler_function": "<source_file>.<starting_function_name>",
  "api_name": "<cloudwatch_api_name>"
}

• Run deploy.py file.
• your config.json and deploy.py should be in same folder.
