This folder has everything you need to deploy TSL as an API.

This is based on the system packages tutorial. For more details on how to work with this read the Google Cloud Run Node.js Samples README.

The basic idea is that the dockerfile is setup to pull the latest version of tsltools (eventually would be nice to have releases rather than just building from the git repo), then upload the resulting docker image to google cloud, where it can be accessed as an api.

Follow the directions here: https://cloud.google.com/run/docs/tutorials/system-packages#handling_incoming_requests

To test locally

   docker build -t tsl/api .  #use --no-cache to ensure a fresh build
   docker run -d -p 8080:8080 tsl/api

then go to localhost:8080. note that this only works with port 8080

to test, run this in the command line

curl -X POST http://localhost:8080/tslsynth -d 'tsl=always assume {}
always guarantee {
  F ([x <- y]);
  F ([x <- z]);
}&target=js&user=1}' -H 'Content-Type: application/x-www-form-urlencoded'

to deploy

   docker build -t tsl/api . 
   gcloud config set project tslapi-2
   gcloud config set run/region us-east1
   gcloud builds submit --tag gcr.io/tslapi-2/tsl --timeout=1h && gcloud run deploy graphviz-web --image gcr.io/tslapi-2/tsl

you need to set a longer time out since it takes so long to build (30 min maybe?).

no idea why it is still called graphviz-web...

• express: Web server framework.
• mocha: [development] Test running framework.
• supertest: [development] HTTP assertion test client.

This API requires requests to include the following parameters:

• tsl: A string representing the specification.
• target: Specifies the target language. Valid options are javascript, python, or xstate.
• user: A string identifier for the user, used for logging purposes.
• logEnabled: A boolean flag that controls logging. It is disabled by default (false). If logging is enabled, it is the responsibility of the API consumers to explain the implications of this setting to users. Enabled logs might be utilized as benchmarks, especially for SYNTCOMP competitions.
