Technology Stack

This section explains the technology used in the Major Manager Server and briefly shows how they are used

Express

• Fast, unopinionated, minimalist web framework for Node.js
• Widely popular framework that is well tested and documented
• Express provides a middleware system that can be used to execute repeated functionality that occurs between receiving and handling requests. For example, when scores are uploaded for a particular Tournament, Express' middleware confirms that the User uploading the scores is logged in and has been assigned the role of Admin. If these checks both pass, we handle the POST request by executing the uploadPlayerScores function (user.routes.js)

app.post(
  '/api/v1/upload_player_scores/:id',
  [authJwt.verifyToken, authJwt.isAdmin],
  adminController.uploadPlayerScores,
);

• Routes, URL parameters and request payloads are easily defined, read and referenced with Express, which makes it ideal to use for building a RESTful API. The above POST request receives the id of the Tournament that is being updated as a parameter in the request URL via :id. This parameter can then be referenced in the uploadPlayerScores function by calling req.params.id. The above request also receives a JSON object that is populated with Players scores. This data can be accessed via a reference to req.body.playerData as seen below (admin.controller.js).

exports.uploadPlayerScores = (req, res) => {
  Admin.addPlayersToPlayersTable(req.body.playerData, (addPlayersErr, addPlayersData) => {
    if (addPlayersErr) {
      res.status(500).send({
        message: 'Error uploading players to players table',
      });
      return;
    }

    Admin.addPlayersToTournamentTable(addPlayersData, req.params.id, req.body.round,
      (addTournamentErr, addTournamentData) => {
