Simple go API that uses gin-gonic to make async requests to the TMB API.

Few things to notice:

• The TMB_ID and TMB_KEY correspond to the app id and app key given by the TMB developer console.
• The GIN_MODE variable can be debug or release, depending on wheter you are developing or deploying to production.
• The PORT variable is the port used by gin to run the server. This should be 8080 (hardcoded in the Dockerfile). YOu can change it but make sure that it makes sense overall.

The file should be in the root directory and look like this

TMB_ID=${TMB_API_ID}
TMB_KEY=${TMB_API_KEY}
GIN_MODE=${debug|release}
PORT=${PORT}

go build -o tmb . and then ./tmb.

or just

go run .

1. docker build -t tmb .
2. docker run -p 8080:8080 --env-file .env tmb:latest

Then you can begin making requests to localhost:${PORT}.

There are two options:

• /pool Creates a pool of async requests using requests.

• /routines Create a goroutine for every pair and makes an individual async or sync request (using the same library requests) for each one, in their own routine.

Both take the same query params and the responses are identical.

String of comma separated integers. The format of a pair is bus_line,stop_id.

Boolean (true or false). Default false.

Defines if every request to the TMB api is made via requests.GetAsync or requests.Get.

}

The time (data.*.time) parameter of the response JSON is given in seconds.

The elapsed times (data.*.elapsed and data.elapsed) parametere of the response JSON is given in miliseconds.
