How to read a sqlite3 database, using node js, synchronously?

Question

exports.allProbes = function() {     var rows = db.all("SELECT * FROM probes;");     return rows; }; 

---

main: var json_values = allProbes(); 

Is it possible to do something like that? I mean, without using a callback function: just, read data (sync mode) from the db. and return a json formatted output?

Thanks.

There are a few npm packages such as better-sqlite3 and sqlite-sync that allow for synchronous SQLite queries. Here's an example:

var sqlite = require("better-sqlite3"); var db = new sqlite("example.db");  var rows = db.prepare("SELECT * FROM probes").all(); console.log(rows);
