pg-query-emscripten

Parse any valid PostgreSQL query in your browser using Javascript!

This builds a pure Javascript port of libpg_query using emscripten, that allows you to parse SQL in the browser into the PostgreSQL parse tree.

Example use cases might include automatically checking for bad query patterns (e.g. LIMIT/OFFSET), understanding which tables a query references, or using structural pg_dump output to produce a schema diagram on the fly.

Usage (Plain JS)

<script src="https://unpkg.com/pg-query-emscripten"></script>
<script>
  console.log(PgQuery.parse("SELECT 1"));
</script>

Usage (npm)

npm install pg-query-emscripten --save

Then import using your favorite tool, e.g.

import PgQuery from 'pg-query-emscripten';

console.log(PgQuery.parse("SELECT 1"));
