Using pg's to_tsquery directly with user input can throw errors. plainto_tsquery sanitizes the user input, but it's very limited (it just puts an and between words), websearch_to_tsquery extends this behavior a little further only between double-quotes, with followedBy operator and negations.
This module allows customizable text-search operators: and, or, followedBy, not, prefix, parentheses, quoted text (same behavior than websearch_to_tsquery).
See the options defaults values
const tsquery = require('pg-tsquery')(/* options can be passed to override the defaults */);
pool.query('SELECT * FROM tabby WHERE to_tsvector(col) @@ to_tsquery($1)', [tsquery(str)]);
// or get a reusable instance
const {Tsquery} = require('pg-tsquery');
const parser = new Tsquery(/* options can be passed to override the defaults */);
// then process your input with parser.parse(str).toString()| inputs | output |
