Aujourd'hui Franklin apprend l'asynchrone de Node.js

Version 1 :
function readContent(callback) {
    fs.readFile("./tmp/tmp.log", function (err, content) {
        if (err) return callback(err);
        callback(null, content);
    })
}

var fileContent = readContent(function (err, content) {
    console.log(content);
    return content;
})

exports.index = function(req, res){
  res.render('index', { 
  	title: 'Express',
  	content: fileContent
  });
};


Version 2 :
function readContent(callback) {
    fs.readFile("./tmp/tmp.log", function (err, content) {
        if (err) return callback(err);
        callback(null, content);
    })
}
 
var fileContent = readContent(function (err, content) {
    exports.index = function(req, res){
    res.render('index', { 
  	title: 'Express',
  	content: fileContent
    });
  };
})
