I know many guys here use vim, me too, I have collect all the method names name some class names base on the /node/doc/*.markdown files
https://github.com/guileen/vim-node/blob/master/dict/node.dict
You can use it if you use vim. example config of vimrc:
au FileType javascript set dictionary+=$HOME/.vim/dict/javascript.dict
au FileType javascript set dictionary+=$HOME/.vim/dict/node.dict
Any question about vim dictionary completion type
