Lavorare su queste sfide ti porterà a scrivere il tuo codice utilizzando uno dei seguenti metodi:

• Clonare questo repository GitHub e completare queste sfide localmente.
• Usare la nostra bozza di progetto su Replit per completare queste sfide.
• Usare un costruttore di siti di tua scelta per completare il progetto. Assicurati di incorporare tutti i file del nostro repository GitHub.

If you use Replit, follow these steps to set up the project:

• Start by importing the project on Replit.
• Next, you will see a .replit window.
• Select Use run command and click the Done button.

When you are done, make sure a working demo of your project is hosted somewhere public. Then submit the URL to it in the Solution Link field.

In this challenge, you will set up a MongoDB Atlas database and import the required packages to connect to it.

Follow this tutorial to set up a hosted database on MongoDB Atlas.

--instructions--

mongoose@^5.11.15 has been added to your project’s package.json file. First, require mongoose as mongoose in myApp.js. Next, create a .env file and add a MONGO_URI variable to it. Its value should be your MongoDB Atlas database URI. Be sure to surround the URI with single or double quotes, and remember that you can't use spaces around the = in environment variables. For example, MONGO_URI='VALUE'.

Note: If you are using Replit, you cannot create a .env file. Instead, use the built-in SECRETS tab to add the variable. Do not surround the values with quotes when using the SECRETS tab.

When you are done, connect to the database using the following syntax:

mongoose.connect(<Your URI>, { useNewUrlParser: true, useUnifiedTopology: true });

--hints--

"mongoose version ^5.11.15" dependency should be in package.json

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/file/package.json').then(
    (data) => {
      var packJson = JSON.parse(data);
      assert.property(packJson.dependencies, 'mongoose');
      assert.match(
        packJson.dependencies.mongoose,
        /^\^5\.11\.15/,
        'Wrong version of "mongoose". It should be ^5.11.15'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

"mongoose" should be connected to a database

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/is-mongoose-ok').then(
    (data) => {
      assert.isTrue(data.isMongooseOk, 'mongoose is not connected');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
