## What it is
The official Terraform Language Server maintained by HashiCorp, implementing the Language Server Protocol to provide IDE features for Terraform and HCL files. It works with any LSP-compatible editor via an editor plugin or built-in client.

## Use cases
- autocomplete and validation for terraform files in my editor
- set up terraform language server for vscode
- get hcl syntax highlighting and diagnostics in neovim
- ide support for terraform modules and variables
- lint and format terraform code inside my ide

## When to choose
- you write Terraform/HCL and want IDE features like completion, hover, and diagnostics in an LSP-compatible editor
- you want the official, actively maintained HashiCorp language server

## When to avoid
- you need language server features for tools other than Terraform/HCL
- your editor does not support the Language Server Protocol

## Facets
- artifact type: service
- maturity: active
- function: editor, developer-tools, parser
- domain: developer-tools, infrastructure-as-code, text-editors
- platform: cross-platform, editor-plugin, go
- tags: terraform, lsp, language-server, hcl, ide-support, hashicorp
