Hi, currently we do not support require()
in threads, there is only importScripts
, which only supports pure-JavaScript modules (via browserify, webpack, onejs etc), and it cannot write to the filesystem.
Perhaps you could move the SQLite-access functions to the main thread, and postMessage from within the worker to access it?
from node-webworker-threads.
so you mean pass this: var db, to the worker?
from node-webworker-threads.
I mean something like:
var Worker = require('webworker-threads').Worker;
var sqlite3 = require('sqlite3').verbose();
var worker = new Worker(function(){
this.postMessage(...) // query to db
this.onmessage = function(event) {
// ...handler result from SQLite3...
};
});
var db = new sqlite3.Database('MyDB.db');
worker.onmessage = function (event) {
// ... do something with db ...
}
Basically doing all DB filesystem operations in the main threads, and have the worker do CPU-intensive work. Something like https://github.com/mozilla/jschannel might be useful to make postMessage
easier to reason with.
