Something like that should work for templates in snipmate format.

function _G.skel(template_path)
  local ls = require('luasnip')
  local template = io.open(template_path, 'r')
  if template == nil then
    print('Template not found')
    return
  end
  local lines = vim.split(template:read('*a'), '\n')
  if lines[#lines] == '' then
    table.remove(lines)
  end
  ls.snip_expand(ls.parser.parse_snippet('', vim.fn.join(lines, '\n')), {})
end

You can try with template file like this:

My ${1:template}!

And then:

:lua skel('/path/to/template')
