(coc.nvim) error: Warning: The 'x' rule requires type information

Question

I'm using coc.nvim for react (typescript) development. I have installed following coc plugins.

• coc-tslint-plugin
• coc-tsserver
• coc-prettier

tslint integration is enabled for prettier in coc-settings.json.

"prettier.eslintIntegration": true,
"prettier.tslintIntegration": true,
"prettier.stylelintIntegration": true,
coc.preferences.formatOnSaveFiletypes": ["typescriptreact"],

When a tsx is saved, it formats the file but it is logging following warning messages.

[coc.nvim] error: Warning: The 'no-array-mutation' rule requires type information.
[coc.nvim] error: Warning: The 'no-object-mutation' rule requires type information.

How do I enable type information for coc.prettier?

Answer 1

After a quick google, I found this, which suggests this is not a coc.nvim issue, but a typescript configuration issue.

my understanding is you'd need to provide the typeCheck: true config option to ts-loader, at the cost of tslint running slower

That said, the issue hasn't had much activity in a year.
