Problem to reproduce

  1. mkdir test
  2. cd test
  3. git init && npm init -y && touch jsconfig.json && touch index.js
    type some code on the index,js
  4. :LspInfo

During this stage all the functionalities is running as aspected

  1. Quit vim
  2. Re-lunch vim, enter index.js, run :LspInfo

Bump as this issue still exists

You don’t seem to have initialised the tsserver configurations (see the officially suggested configurations).

The gist is you need to add the following line to your configurations:

local lspconfig = require('lspconfig')

lspconfig.tsserver.setup({
    settings = { ... },
    on_attach = on_attach,
    capabilities = capabilities,
})
