Set up your editor

Since v0.3.0

An app’s code is Go, and its pages are templ files (.templ): HTML with Go expressions, compiled to Go. Your editor needs to know both.

Go

Install your editor’s Go support, which runs gopls, Go’s language server: the Go extension in VS Code, the Go plugin in other JetBrains IDEs (built into GoLand), nvim-lspconfig’s gopls in Neovim.

templ

Install templ’s extension: “templ-vscode” in VS Code, the “Templ” plugin in GoLand, the templ language server in Neovim. They highlight .templ files, complete Go in them, and report errors as you type.

The extensions start templ’s language server, templ lsp, from your PATH. Projects use templ as a tool of their module (go tool templ), so install the same version for the editor too: the version is on the github.com/a-h/templ line of the project’s go.mod.

Formatting

gofmt (your editor runs it on save) formats Go; go tool templ fmt . formats .templ files. go tool anetos dev regenerates the templ code and the models’ typed columns as you save, so you don’t run the generators yourself.
