This is the api to support the concurrency exercise here: https://github.com/modulitos/async-graph-exercise
The API
This API is an HTTP server that returns information about the nodes in a graph, with various delays in the response times for each node. It only serves GET requests.
Each node has a reward and children.
For example:
GET http://localhost:7878/node/a
returns JSON of the form:
{
"children": [ "c", "e" ],
"reward": 100
}
Where the children in this example can be accessed via: GET http://localhost:7878/node/c GET http://localhost:7878/node/e
How to run the server locally
The local server uses Warp, which can be started like so:
cargo run --bin warp_server
The server will start at port 7878.
curl http://localhost:7878/node/a
{"children":["e","c"],"reward":100}
Deploying to AWS Lambda
The API is currently deployed at graph.modulitos.com
For example:
curl https://graph.modulitos.com/node/a
{"children":["e","c"],"reward":100}
To create a package for deployment to AWS Lambda
./deploy.sh
Then upload the resulting rust.zip file to the Lambda function
some notes while setting this up on AWS Lambda:
