# Warn the user if they have set the default server name to tsserver to match upstream (us)
# The name "tsserver" has been deprecated in lspconfig, and now should be called ts_ls. This

message = ''
As of a recent lspconfig update, he `tsserver` configuration has been renamed
to `ts_ls` to match upstream behaviour of `lspconfig`, and the name `tsserver`
is no longer considered valid by nvf. Please set `vim.languages.ts.lsp.server`
to `"ts_ls"` instead of to `${cfg.lsp.server}`

Please see <https://github.com/neovim/nvim-lspconfig/pull/3232> for more details
about this change.
