" Default: 0
let g:deoplete#sources#ternjs#docs = 1

let g:deoplete#sources#ternjs#filter = 0

" Whether to use a case-insensitive compare between the current word and 
" potential completions. Default 0
let g:deoplete#sources#ternjs#case_insensitive = 1

" When completing a property and no completions are found, Tern will use some 
" heuristics to try and return some properties anyway. Set this to 0 to 
" turn that off. Default: 1
let g:deoplete#sources#ternjs#guess = 0

" Determines whether the result set will be sorted. Default: 1
let g:deoplete#sources#ternjs#sort = 0

                \ 'vue',
                \ '...'

If you are using tern_for_vim, you also want to use the same tern command with deoplete-ternjs

" Use tern_for_vim.
let g:tern#command = ["tern"]
let g:tern#arguments = ["--persistent"]

Also if you are using add loadEagerly - * many files * - this to your .bashrc or .zshrc, this will allow you load all files you need when ternjs is started.
