Different ac behaviour on js and ts files

[LionyxML]

Hello again! Sorry to spam you guys like this. :D

As I am more then happy editing a new .tsx / .ts project, but I happened to be maintaining some older JS code also.

And now emacs behaves differently. No auto complete and no docs over functions. I know VsCode made me spoiled by providing the same linting for both .js and .ts files, am I asking to much expecting it to behave the same?

Inside a .tsx file if I type console. I get the following suggestions:

The same if the file is a .ts:

But inside a .js (also jsx) file:

My modes:

Inside JS(X) files:

RJSX mode defined in ‘rjsx-mode.el’:
Major mode for editing JSX files.

Enabled minor modes: All-The-Icons-Completion All-The-Icons-Ibuffer
All-The-Icons-Ivy-Rich Auto-Composition Auto-Compression
Auto-Encryption Blink-Cursor Centaur-Tabs Column-Number Cursor-Sensor
Display-Line-Numbers Doom-Modeline Electric-Indent File-Name-Shadow
Flycheck Flycheck-Pos-Tip Font-Lock Git-Gutter Global-Auto-Complete

Mouse-Wheel Prettier-Js Shell-Dirtrack Smartparens Tooltip

Treemacs-Fringe-Indicator Treemacs-Git Xterm-Mouse Yas

Inside TS(X) files:

Web mode defined in ‘web-mode.el’:
Major mode for editing web templates.

Enabled minor modes: All-The-Icons-Completion All-The-Icons-Ibuffer

For comparison, on both js(x) and ts(x) inside VSCode:

@LionyxML We actually used tide for .ts and .tsx and js2-refactor-mode for js. But really, we should be using those for both. I just haven't gotten around to it because I don't really do much .js coding these days.

Would it be acceptable to put a jsconfig.json in your project, and typescript language server in your package dependencies?

If so, we could see if that file exists, and then load tide in stead of a vanilla JS environment.

Oh, and no need to apologize ever. Really appreciate ways that this can be improved.

Hello there!

I asked around about having a fallback for when jsconfig.json or tsconfig.json is not present into the directory, but I guess I am too dumb to understand the reason (lol).

In short. For projects I maintain, it is ok to do so. For projects I do not have any decision power, I will probably have to manage it locally.

I would love this feature, but I do not think it is for everyone (due to jsconfig mandatory presence), it might be some option to set in frontside custom-group.

Points to VSCode in this regard. If no config is present, it runs typescript in the background using its own defaults.

There are a couple of reasons.

1. on javascript projects, generally, there is no dependency on typescript in package.json. As a result, you can't even start the tsserver because where is the actual js code to do so?
2. without a jsconfig.json how can you know which typescript compiler options to use?

Maybe we can have defaults for these? Not sure how that could work...
