Implementing TypeORM in an ExpressJS project (initialized using Express generator)

I am currently working on an ExpressJS project that was created using the Express generator. My goal is to integrate TypeORM into this project, but I am facing some challenges in achieving that.

After attempting to modify the /bin/www file with the following code snippet:

typeorm.createConnection().then((connection) => {

  /**
   * Create HTTP server.
   */

  server = http.createServer(app);

  /**
   * Listen on provided port, on all network interfaces.
   */

  server.listen(port);
  server.on('error', onError);
  server.on('listening', onListening);
}).catch(err => {
  console.log(err);
});

I encountered an issue where I received a "default connection was not found" error whenever I tried to use TypeORM within an ExpressJS route.

Answer №1

Make sure to check the location where you are using getManager/getRepository in your typeorm code. These methods should only be called after a connection has been successfully established.
