Create and develop applications in source code locally in Visual Studio Code Desktop with the ServiceNow SDK. Build and install applications to make your changes available on an instance.
After installing the ServiceNow SDK, you can authenticate to an instance to create applications or convert existing applications using the ServiceNow SDK command-line interface (CLI).

In Visual Studio Code, start developing your application in source code with ServiceNow Fluent, writing custom JavaScript modules, or adding third-party libraries.

When your changes are ready, build and install the local application on the instance with the ServiceNow SDK CLI. Download and transformFetch changes to the application metadata from the instance to keep the application up to date locally before making additional changes.

Learn how to get started developing applications with the ServiceNow SDK in the following topics.
* **[Define application metadata in code with ServiceNow Fluent and the ServiceNow SDK](https://servicenow-prod.fluidtopics.net/hjgD9Vg64uwp0kMBBzJcIw)**   
  Define application metadata in code with ServiceNow Fluent and the ServiceNow SDK.
* **[Create and use JavaScript modules in applications with the ServiceNow SDK](https://servicenow-prod.fluidtopics.net/yeUPdaCTbIDhv4Q7hPRTnw)**   
  Optimize your codebase by defining reusable code blocks with JavaScript modules and the ServiceNow SDK.
* **[Use third-party libraries in applications with the ServiceNow SDK](https://servicenow-prod.fluidtopics.net/YbgBAPdytbg2mOcPhsb~gA)**   
  Call third-party libraries in your application to use existing open-source functionality with the ServiceNow SDK.
* **[Downloading dependencies with the ServiceNow SDK](https://servicenow-prod.fluidtopics.net/VksjUu5ubzAvjCk1G9w7qg#downloading-dependencies-now-sdk)**   
  Download application dependencies and TypeScript definitions from an instance for IntelliSense and validation of scripts and ServiceNow Fluent code.Download the application dependencies configured in the now.config.json file and script dependencies, such as TypeScript type definitions for Glide APIs and script includes, from the instance.
* **[Build and installdeploy an application with the ServiceNow SDK](https://servicenow-prod.fluidtopics.net/GCQJKq4yOxXXoDY~k7hdzw)**   
  Build and installdeploy a local application developed with the ServiceNow SDK on a ServiceNow instance.
