Vim works fairly well for Deno/TypeScript if you install

After CoC is installed, from inside Vim, run`:CocInstall coc-tsserver` and

From now on, things like `gd` (go to definition) and `gr` (goto/find references)
should work.
##### ALE
ALE integrates with Deno's LSP out of the box and should not require any extra
configuration. However, if your Deno executable is not located in `$PATH`, has a
different name than `deno` or you want to use unstable features/APIs, you need
to override ALE's default values. See
[`:help ale-typescript`](https://github.com/dense-analysis/ale/blob/master/doc/ale-typescript.txt).
ALE provides support for autocompletion, refactoring, going to definition,
finding references and more, however, key bindings need to be configured
manually. Copy the snippet below into your `vimrc`/`init.vim` for basic
configuration or consult the
[official documentation](https://github.com/dense-analysis/ale#table-of-contents)
for a more in-depth look at how to configure ALE.
ALE can fix linter issues by running `deno fmt`. To instruct ALE to use the Deno
formatter the `ale_linter` setting needs to be set either on a per buffer basis
(`let b:ale_linter = ['deno']`) or globally for all TypeScript files
(`let g:ale_fixers={'typescript': ['deno']}`)
```vim
" Use ALE autocompletion with Vim's 'omnifunc' setting (press <C-x><C-o> in insert mode)
autocmd FileType typescript set omnifunc=ale#completion#OmniFunc
" Make sure to use map instead of noremap when using a <Plug>(...) expression as the {rhs}
nmap gr <Plug>(ale_rename)
nmap gR <Plug>(ale_find_reference)
nmap gd <Plug>(ale_go_to_definition)
nmap gD <Plug>(ale_go_to_type_definition)
let g:ale_fixers = {'typescript': ['deno']}
let g:ale_fix_on_save = 1 " run deno fmt when saving a buffer
```
#### Emacs
Emacs works pretty well for a TypeScript project targeted to Deno by using a
