About

Originally, this module is part of @fxjs/orm. It's used synchronize model tables in supported dialects.

But now, it could run without @fxjs/orm, just install @fxjs/db-driver instead 🚀 Sorry there is no API documentation for now but there are a couple of tests you can read and find out how to use it if you want.

Version Match

Example

Install @fxjs/db-driver. Create a file with the contents below and change insert your database credentials. Run once and you'll see table ddl_sync_test appear in your database. Then make some changes to it (add/drop/change columns) and run the code again. Your table should always return to the same structure.

const DBDriver   = require("@fxjs/db-driver");
const mysql = require("mysql");
const Sync  = require("@fxjs/sql-ddl-sync").Sync;

const dbdriver = DBDriver.create("mysql://username:password@localhost/database");

const sync = new Sync({
	dbdriver: dbdriver,
	debug   : function (text) {
		console.log("> %s", text);
	}
});

sync.defineCollection("ddl_sync_test", {
	id     : { type: "serial", key: true, serial: true },
	name   : { type: "text", required: true },
	age    : { type: "integer" },
	male   : { type: "boolean" },
	born   : { type: "date", time: true },
	born2  : { type: "date" },
	int2   : { type: "integer", size: 2 },
	int4   : { type: "integer", size: 4 },
	int8   : { type: "integer", size: 8 },
	float4 : { type: "number",  size: 4 },
	float8 : { type: "number",  size: 8 },
	photo  : { type: "binary" }
});

try {
	sync.sync()
	console.log("> Sync Done");
} catch (err) {
	if (err) {
		console.log("> Sync Error");
		console.log(err);
	}
}

process.exit(0);

Test

To test, first make sure you have development dependencies installed. Go to the root folder and do:

npm install

Then, just run the tests.

npm test

If you have a supported database server and want to test against it, first install the module:

And then run:

URI=mysql://username:password@localhost/database fibjs test/run-db

This repo is checked out from Diogo Resende's node-sql-ddl-sync, which is one part of orm, and orm is the original source of @fxjs/orm. Thx a lot to him and his partner.
