Example of how to do routing in a Google Cloud Function

gcf-routing-snippet.js

const router = require('gcf-api-router')();

router.route('/result')
  .get(getAllResults) //GET  api/result
  .post(storeResult); //POST api/result

router.route('/result/:id')
  .get(getSpecificResult); //GET api/result/[id]

function getAllResults(req, res) {
  //get all results
  res.send('returning results..');
}

function storeResult(req, res) {
  const homeTeamScore = JSON.parse(req.body).homeTeamScore;
  //store result 
  res.send('result posted: ' + homeTeamScore);
}

function getSpecificResult(req, res) {
  const idParam = req.params.id
  //get result
  res.send('returning result with id: ' + idParam)
}

//This function (entrypoint) is configured in the Cloud Functions UI
exports.entrypoint = function (req, res) {
    // Some request processing/verification/logging can be done here
    router.onRequest(req, res);
};
