Is it possible in Neovim to use JsDoc for typechecking of javascript files? Right now I use default LSP configurations for eslint and tsserver provided by lspconfig:
-- init.lua
require('lspconfig').tsserver.setup({})
require('lspconfig').eslint.setup({})
It works but seems to provide typechecks only for typescript files.
Just add a // @ts-check comment in the file. This will trigger type checking on normal JS files with TypeScript, as well as with JSDoc.
Example without // @ts-check:
Example with // @ts-check (notice line 4):
Here is an example with JSDoc being checked:
lsp-zero for my lsp setup and not lspconfig directly, maybe that's related? The file I showed you is not in a TS project, it was a blank directory. My LSP config was otherwise nothing special.
return statement is highlighted as an error in VSCode because return type of the function as written in the JsDoc is {number} while in the code it can return null. Vim doesn't seem to capture that even if I add // @ts-check on the top line of the file.
