Azure Functions et Visual Studio Code

Azure Functions et Visual Studio Code

Dans cette capsule de Cloud en 5 minutes, Je partage une découverte récente qui parmet de développer et déployer des Azure Functions à partir de Linux, Mac et WIndows, and utilisant Visual Studio Code.

Voici le code pour la function et le fichier pour installer tedious.

TimerTriggerJS.js
var Connection = require('tedious').Connection;  
var Request = require('tedious').Request  
var TYPES = require('tedious').TYPES;

module.exports = function (context, myTimer) {

    var _currentData = {};

    var config = {
        userName: 'frankadmin',
        password: 'MyPassw0rd!',
        server: 'clouden5srv.database.windows.net',
        options: {encrypt: true, database: 'clouden5db'}
    };

    var connection = new Connection(config);
    connection.on('connect', function(err) {
        context.log("Connected");
        getPerformance();
    });

    function getRandom(min, max) {
        return Math.random() * (max - min) + min;
    }

    function getPerformance() {

        request = new Request("SELECT 'Best' = MIN(FivekmTime), 'Average' = AVG(FivekmTime) FROM RunnerPerformance;", function(err) {
        if (err) {
            context.log(err);}
        });

        request.on('row', function(columns) {
            _currentData.Best = columns[0].value;
            _currentData.Average = columns[1].value;;
            context.log(_currentData);
        });

        request.on('requestCompleted', function () {
            saveStatistic();
        });
        connection.execSql(request);
    }


    function saveStatistic() {

        request = new Request("UPDATE Statistic SET BestTime=@best, AverageTime=@average;", function(err) {
         if (err) {
            context.log(err);}
        });
        request.addParameter('best', TYPES.Int, _currentData.Best);
        request.addParameter('average', TYPES.Int, _currentData.Average);
        request.on('row', function(columns) {
            columns.forEach(function(column) {
              if (column.value === null) {
                context.log('NULL');
              } else {
                context.log("Statistic Updated.");
              }
            });
        });

        connection.execSql(request);
    }

    context.done();
};
