> I still believe Phoenix LiveView is a really, really good tech and currently wish that Svelte could implement something like that. Not what you meant, but there's this: https://github.com/woutdp/live_svelte > I did fail to understand how to use the VS Code debugger to step through functions. Did you have any luck with the ElixirLS extension? https://github.com/elixir-lsp/elixir-ls

In Ask HN: Why Isn't Elixir More Popular?

Ask HN: Elixir LSP doesn't work on VSCode and Neovim. Any solutions?

I have tried installing Elixir+Erlang through Homebrew (as instructed by the official Elixir website): https://elixir-lang.org/install.html#macos I also tried uninstalling them and installing through ASDF and I made sure that they both had the same version (27) as mentioned in this article: https://elixir-ko.github.io/install.html This Issue mentions that Elixir may be incompatible with the most recent OpenSSL versions, but I don't want to downgrade OpenSSL: https://github.com/erlang/otp/issues/4577#issuecomment-925962048. Also: https://elixirforum.com/t/elixirls-cannot-connect-to-server-in-vscode/55345/8 I also did every tip mentioned on the Github page of the Elixir LSP: https://github.com/elixir-lsp/elixir-ls?tab=readme-ov-file#troubleshooting Several hours later, I still can't use the Elixir LSP in VSCode. This is the error I keep get

Header must provide a Content-Length property. {"{\"jsonrpc\"":"\"2.0\",\"method\":\"window/logMessage\",\"params\":{\"message\":\"Started ElixirLS v0.21.3\",\"type\":3}}Content-Length: 121"} Shutting down server. ``` And ``` Client ElixirLS - elx: connection to server is erroring. Header must provide a Content-Length property. {"\u001b[6 qcontent-length":"103"} Shutting down server. ``` This isn't supposed to be like this, and a search on Google shows many people have this problem. I like Elixir and BEAM, but the tooling is not comparable to Rust, Haskell, Go, etc. Even with Python (which has one of the worst toolings), all I need to do before using the language is: 1. Install Python through Homebrew or a binary. 2. Install the plugin on VSCode. 3. Profit.
