    Serverless Framework Support

    Extetion provides limited serverless framework support: ServerlessIDE Serverless Framework Support

    Note: ServerlessIDE does not support validation of resources and external imports and parameters for Serverless Framework


    The following settings are supported:

    • serverlessIDE.validate: Enable/disable validation feature
    • serverlessIDE.hover: Enable/disable hover documentation
    • serverlessIDE.completion: Enable/disable autocompletion
    • serverlessIDE.validationProvider : Validation provider. Can be default (uses json schema) or cfn-lint
    • serverlessIDE.telemetry.enableTelemetry : Enable/disable telemetry and crash reporting

    cfn-lint is used as default validator More information about installation and configuration can be found here

    • serverlessIDE.cfnLint.path : Path to cfn-lint command (default to cfn-lint)
    • serverlessIDE.cfnLint.appendRules : Additional cfn-lint rules
    • serverlessIDE.cfnLint.ignoreRules : Array of rules to ignore

    Language settings:

    • [yaml]: VSCode-YAML adds default configuration for all yaml files. More specifically it converts tabs to spaces to ensure valid yaml, sets the tab size, and allows live typing autocompletion. These settings can be modified via the corresponding settings inside the [yaml] section in the settings:
      • editor.insertSpaces
      • editor.tabSize
      • editor.quickSuggestions


    ServerlessIDE collects usage data and metrics to help us improve the extension for VS Code.

    What data is collected?

    ServerlessIDE collects anonymous information related to the usage of the extensions, such as which commands were run, as well as performance and error data.

    How do I disable telemetry reporting?

    On Windows or Linux, select File > Preferences > Settings. On macOS, select Code > Preferences > Settings. Then, to silence all telemetry events from the VS Code shell and disable telemetry reporting, add the following option.

    "serverlessIDE.telemetry.enableTelemetry": false

    IMPORTANT: This option requires a restart of VS Code to take effect.

    NOTE: We also respect the global telemetry setting telemetry.enableTelemetry; if that is set to false, ServerlessIDE telemetry is disabled. For more information see Microsoft’s documentation.
