    Avant de commencer

    Your system must meet the following minimum requirements to use the latest version of the ServiceNow SDK:
    • Node.js v20.18.0
    • npm v8.19.3
    To install or upgrade Node.js or npm, see the installation instructions on the npm website.

    Role required: admin

    Pourquoi et quand exécuter cette tâche

    The ServiceNow SDK is available as an npm package from the public npm registry. The ServiceNow SDK supports integrating with ServiceNow instances beginning with the Washington DC release.

    In the following procedure, you install the ServiceNow SDK within a new application using npx rather than globally. To install the ServiceNow SDK globally, use the npm install --global @servicenow/sdk command.

    Remarque :
    If you use npx to install the ServiceNow SDK in application rather than globally, you must use npx @servicenow/sdk [command] rather than now-sdk [command] with the ServiceNow SDK CLI.

    Procédure

    1. Open a command-line tool on your system.
    2. Verify that your system meets the requirements.
      1. Enter node -v​ to check if you have Node.js installed and which version.
      2. Enter npm -v to check if you have npm installed and which version.
    3. Create a local directory for your application.
    4. Change directories into the directory for your application using the cd command. 
      cd <path/to/directory>
    5. Create an application with the ServiceNow SDK.

      npx @servicenow/sdk auth --add <instance>
