@archseer there is also an eslint language server. It is quite common nowadays to use it along with It allows code actions to fix eslint issues. It even can act as a super fast code formatter by reading your It is available on npm: https://github.com/hrsh7th/vscode-langservers-extracted |

Not a useful comment, but this is the only one thats preventing me from using this editor. Somehow I could not get prettier also working, but thats may be my fault. |

@amritk, helix has just been a splendid example of how to design a powerful editor like nvim but without nvim's notorious difficulty to configure, which lead to the creation of various nvim distributions (not that I don't like the configurability but only when I need to deviate from the OOB experience which should just work for any language supported that is installed). I just hope that helix won't have distributions created like this in the future. I think that in order to achieve this, stuff like that configuration you pasted above, should be included by default in helix. Thanks to your config, I got React/TS/ESLint+Prettier to work just as it does in VSCode. Here's my config. I think the number of deviations from the standard configs of these tools/LSPs should be kept to a minimum, so the standard behavior can become the baseline. For example even helix docs suggests we don't need to set any args for prettier: https://github.com/helix-editor/helix/wiki/External-formatter-configuration#prettier [language-server.eslint]
args = ["--stdio"] # should come by def with helix
command = "vscode-eslint-language-server"
[language-server.eslint.config]
validate = "on" # I assume this enabled eslit to validate the file, which now shows me counts for errors, warnings, etc in helix
experimental = { useFlatConfig = false } # not sure why this is here
rulesCustomizations = []
run = "onType"
problems = { shortenToSingleLine = false }
nodePath = "" # seems redundant, why do we need to override this, should get detected autom.
[language-server.eslint.config.codeAction]
[language-server.eslint.config.codeAction.disableRuleComment]
enable = true
___location = "separateLine"
[language-server.eslint.config.codeAction.showDocumentation]
enable = true # why?
[language-server.eslint.config.codeActionOnSave]
enable = true
mode = "fixAll"
[language-server.eslint.config.workingDirectory]
mode = "___location" # do we need to override this?
[language-server.typescript-language-server.config]
documentFormatting = false # use eslint instead, do we have to override this ourselves? I think if eslint LSP is detected and enabled, this should be done automatically for us as generally everyone lets eslint take over linting+prettying, which uses prettier by default if detected by it
[[language]]
name = "typescript"
language-servers = [{ except-features = ["format"], name = "typescript-language-server" }, "eslint"] # shouldn't need to override this
roots = ["package-lock.json", "tsconfig.json", ".prettierrc.json"] # shouldn't need to override this
formatter = { command = "prettier" }
auto-format = true

formatter = { command = "prettier" } # works without any args, the modifications end up in the buffer, unsaved

Is it possible to change the language server of typescript to eslint?
I tried making a user-level languages.toml to overwrite the typescript language to use eslint but it just acted as though no language server existed.
