• Auto-completion support
  1. Terraform high level types (variable, resource, data, module ...) auto completion support.
  2. resource types (aws_dynamodb_table ...) auto completion support for aws, azure, datadog, google, oci and openstack
  3. resource | data | module | output | variable property types auto completion support
  4. resource | data 1-level nested block property types auto completion support
• Syntax highlighting for .tf and .tfvars files (and .hcl)
• Automatic formatting using terraform fmt
• Automatically closes braces and quotes
• Adds a command for running terraform validate
• Linting support with the help of tflint
• Browse document symbols
• Browse workspace symbols
• Peek definition
• Goto definition
• Find references
• Completion for variables and outputs
• Rename variables, resource, and data types and all references
• Show variable values on hover
• CodeLens shows if a section is referenced

• Indexing support is no longer experimental
• Indexing support no longer requires a separate tool (HCL parsing is now built directly into the plugin)
• Rename refactoring now supports all types
• Hovering a variable shows the default value
• A code lens shows how often a resource (or variable, or data) is referenced
• Terraform now works with Visual Studio LiveShare (thanks to @lostintangent)

The plugin also ships a formatter integration which uses terraform fmt for formatting files. Formatting can be enabled or disabled by setting editor.formatOnSave or [terraform]editor.formatOnSave to true or false.

You can lint your terraform templates by invoking the command Terraform: Lint from within VSCode.

Linting is supported with the help of tflint, either download it and add it to your path or can configure terraform.lintPath to point to your tflint executable. tflint will be executed with the workspace directory as the current working directory so you can configure tflint by dropping a .tflint.hcl file in your workspace root. You can change the configuration file path by supplying the configuration option terraform.lintConfig.

You can terraform validate your project by invoking the command Terraform: Validate from within VSCode.

terraform validate is invoked with the workspace root as current working directory and with the setting terraform.templateDirectory as template directory, by default this setting is "templates" (relative to workspace root).

Because the output of terraform validate is not parseable the output is just dumped into the output tab.

The plugin indexes all the terraform files in the workspace by default and enables some advanced features, like Goto Definition and Show references based on information gathered during indexing.

Indexing is enabled by default but can be disabled using terraform.indexing.enable.
