5 years ago Okay. 2 things. 1) you're creating a instance of gun with peers, and then creating a different one without peers and just the database. Those don't talk or know about each other..
var Gun = new Gun( peers );
var GUn = new Gun( ... );2) peers don't just automatically sync. 'upstream' (peers) get data that is pushed, but if another node is connected to that one, it won't actually get any data without doing some sort of map() to pull the information in.

i tried to sync sqlite db to another sqlite db but it was not syncing.
this is my code. * sqlite_client1.js *** var vfs = require( "sack.vfs" ); var vol = vfs.Volume( "MountName", "vfsFile.dat" );
var Gun = require('gun'); require('gun-db');
var peers = [ 'http://localhost:8081/gun', 'http://localhost:8082/gun', ] // Create a new gun instance var gun = Gun(peers);
var gun = Gun({ file: false // turn off pesky file.js data.json default , db: { file: "gun.db", exclusive : false // default } }); var data = gun.get('data').put({name: 'abc', age: 41});
function dumpDatabase() { var db = vfs.Sqlite( "gun.db" ); //var db = vfs.Sqlite( "$sack@Mount$gun.db" ); var tables = db.do( "select tbl_name from sqlite_master where type='table'" ); console.log( "Tables:", tables ); var records = db.do( "select * from record" ); console.log( "records:" ); records.forEach( rec=>{ console.log(
s:${rec.soul} f:${rec.field} v:${rec.value} r:${rec.relation} s:${rec.state}); } ); }dumpDatabase()
* sqlite_client2.js *** var vfs = require( "sack.vfs" ); var vol = vfs.Volume( "MountName", "vfsFile.dat" );
var Gun = require('gun'); require('gun-db');
var peers = [ 'http://localhost:8081/gun', 'http://localhost:8082/gun', ] // Create a new gun instance var gun = Gun(peers);
var gun = Gun({ file: false // turn off pesky file.js data.json default , db: { file: "gun2.db", exclusive : false // default } }); var data = gun.get('data').put({name: 'xyz', age: 28});
function dumpDatabase() { var db = vfs.Sqlite( "gun2.db" ); //var db = vfs.Sqlite( "$sack@Mount$gun.db" ); var tables = db.do( "select tbl_name from sqlite_master where type='table'" ); console.log( "Tables:", tables ); var records = db.do( "select * from record" ); console.log( "records:" ); records.forEach( rec=>{ console.log(
s:${rec.soul} f:${rec.field} v:${rec.value} r:${rec.relation} s:${rec.state}); } ); }dumpDatabase()
server1.js

i am sharing the four files, which i used to sync sqlite db using GUN DB. i ran all files using node command i.e node sqlite_client1.js and node server1.js etc. so am i making any mistake while writing a code. kindly check above code and please tell me.
