The real PostgreSQL parser, exposed for nodejs.

Install node-gyp globally
npm install node-gyp -gnpm install @sqlutils/parseParses the sql and returns a Promise for the parse tree (or returns the parse tree directly in the sync version). May reject with/throw a parse error.

Parses the contents of a PL/PGSql function, from a CREATE FUNCTION declaration, and returns a Promise for the parse tree (or returns the parse tree directly in the sync version). May reject with/throw a parse error.
const parser = require('@sqlutils/parse');
parser.parseQuery('select 1').then(console.log);
