# Overview
This is an extremely simple framework to facilitate developing rest services running as lambda services in aws.
Features
* VERY simple
* One lambda function required to host a whole rest service
* Allows for local development
Shortcomings
* Only supports Python
* Does not support non json responses
* Query variables not supported yet
* Headers not exposed in route handlers
* Many others
Please raise issues for any enhancements or bugs.

# Workflow in a nutshell
1. Install
2. Create project
3. Develop and test locally
4. Build zip file for aws lambda
5. Upload to aws
6. If not done goto 3
# Installing
Install the package using pip:
```shell
pip install aws_lambda_mess
```
After a successful installation check that the cli works:
```shell
alm --help
```
# Create and run a new project
Create a new project using th cli:
```shell
alm new demo
```
This will:
* create a new directory with the name you specified
* populate the directory with some standard boilerplate
A sample app has been created for you in ```src\app.py```
```python
from aws_lambda_mess.framework.Route import Route
from aws_lambda_mess.framework.success import success
from aws_lambda_mess.framework.failures import bad_request
from aws_lambda_mess.framework.server import run
def index(params, body):
return success({"Hallo": "Index"})
def greet(params, body):
return success({"Hallo": params["name"]})
def default(params, body):
return bad_request()
routes = [
Route(method_pattern="GET", path_pattern="/", handler=index),
Route(method_pattern="GET", path_pattern="/greet/<name>", handler=greet),
Route(method_pattern=".*", path_pattern=".*", handler=default)
]
from aws_lambda_mess.framework.lambda_dispatcher import get_handler
lambda_handler = get_handler(routes)
if __name__ == "__main__":
run(9000, routes)
```
To run the app locally simply run:
```shell
python app.py
```
A webserver serving the above routes will spin up on port 9000
```shell
$ curl -X GET localhost:9000/
{"Hallo": "Index"}
$ curl -X GET localhost:9000/greet/somebody
{"Hallo": "somebody"}
$ curl -X GET localhost:9000/whatwhere -v
Note: Unnecessary use of -X or --request, GET is already inferred.
* Trying 127.0.0.1:9000...
* Connected to localhost (127.0.0.1) port 9000 (#0)
> GET /whatwhere HTTP/1.1
> Host: localhost:9000
> User-Agent: curl/7.88.1
> Accept: */*
>
* HTTP 1.0, assume close after body
< HTTP/1.0 400 Bad Request
< Server: BaseHTTP/0.6 Python/3.9.13
< Date: Sun, 30 Apr 2023 06:38:25 GMT
<
* Closing connection 0
```
# Build the aws lambda zip
To build the package to be uploaded to aws simply run:
```shell
alm build
```
This will create a zip file in the ```dist``` directory called ```package.zip```
Upload this package to aws lambda either in the lambda console or via s3.
# Install the zip as a lambda
Once the package has been uploaded change the ```handler``` setting under runtime settings to ```app.lambda_handler```
Now test the package with some of these json test cases:
## Test /
```json
{
"body": "{}",
"resource": "/{proxy+}",
"path": "/",
"httpMethod": "GET",
"isBase64Encoded": true,
}
```
Returns
```json
{
"isBase64Encoded": false,
"statusCode": 200,
"headers": {
"Content-Type": "application/json"
},
"body": "{\"Hallo\": \"Index\"}"
}
```
## Test /greet/somebody
```json
{
"body": "{}",
"resource": "/{proxy+}",
"path": "/greet/somebody",
"httpMethod": "GET",
"isBase64Encoded": true
}
```
Returns
```json
{
"isBase64Encoded": false,
"statusCode": 200,
"headers": {
"Content-Type": "application/json"
},
"body": "{\"Hallo\": \"somebody\"}"
}
```
## Test invalid route or method
```json
{
"body": "{}",
"resource": "/{proxy+}",
"path": "/greet/somebody",
"httpMethod": "POST",
"isBase64Encoded": true
}
```
```json
{
"isBase64Encoded": false,
"statusCode": 400
}
```
This json gets converted to a proper http response by the proxy.
# Configure the api gateway
The API gateway you attach to the lambda needs to look like this
and the methods needs to be defined to look like this:
# Developer section
Run tests
```json
???
```
Build aws_lambda_mess
```shell
hatch build
```
Upload to pip
```shell
py -m twine upload dist/* --user johanjordaan
