vim version:

Vim 8.0 (MS-Windows 64-bit GUI version with OLE support)

vimrc

Plug 'mitermayer/vim-prettier', {
            \ 'do': 'yarn install',
            \ 'for': ['javascript', 'typescript', 'css', 'less', 'scss'] }

" Disable auto formatting of files that have @format tag
let g:prettier#autoformat = 0

" max line lengh that prettier will wrap on
let g:prettier#config#print_width = 80

" number of spaces per indentation level
let g:prettier#config#tab_width = 4

" use tabs over spaces
let g:prettier#config#use_tabs = 'false'

origin code

function aLongLongLongFunction(barbarbar, foofoofoo, boobooboo, barbarbar, balabalabala) {
    console.log('lalalala');
}

after prettier

function aLongLongLongFunction(
    barbarbar,
    foofoofoo,
    boobooboo,
    barbarbar,
    balabalabala,  // add an extra comma here
) {
    console.log('lalalala');
}

After writting the issue, I found a configuration to solve this problem.

" none|es5|all
let g:prettier#config#trailing_comma = 'none'
