Install Dependencies

To install dependencies from a package.json file in Visual Studio Code, you can use the integrated terminal. Here are the steps:

• Open the integrated terminal by going to View > Terminal or using the shortcut Ctrl+` (backtick).

• In the terminal, navigate to the directory where the package.json file is located.

• Run the command npm install or yarn install, depending on your preferred package manager.

• The package manager will read the package.json file and install all the dependencies specified in it.

• Wait for the installation process to complete. You should see progress indicators or a success message for each installed dependency.

• Once the installation is finished, the dependencies listed in the package.json file will be installed in a node_modules directory in your project.

Setting the keycloak

• Create a folder on service directory named: keycloak-public-keys

• Inside that folder create a file GRxxx....................xxxxx60fA

for keycloak file please contact Backend Team

Setup Database

Before proceeding with these steps, ensure that you have MongoDB installed on your computer. For a graphical user interface (GUI) for MongoDB, you can choose to install Robo 3T.

• Obtain the latest database dump from the backend team.

• Restore the database in your local environment using the following command:

  For Windows/Linux: mongorestore <name you want to give the db> <directory or file to restore>

  For macOS: mongorestore -d <name you want to give the db> <directory or file to restore>

Note: Add <name you want to give the db> to mongoDB url in .env file.
