Template generation

To generate Go code from *.templ files, use the templ command line tool.

templ generate

The templ generate command will recurse into subdirectories and generate Go code for every *.templ file it finds.

The command will output a list of files that it processed, how long it took, and the total elapsed time.

Advanced options​

The templ generate command has a --help option that prints advanced options.

These include the ability to generate code for a single file and to choose the number of parallel workers that templ generate uses to create Go files.

By default templ generate uses the number of CPUs that your machine has installed.
