## reactive-stack-js-mysql-poc
See [reactive-stack-js](https://github.com/reactive-stack-js) for more info.
This is a MySQL Change Data Capture (CDC) POC for those who may want to use MySQL instead of MongoDB, which is used in all reactive-stack-js packages.
In this POC, I am using [Docker](https://www.docker.com/) to run MySQL because... well, why not?
You can, of course, still use your own MySQL installation instead. Just skip all the Docker stuff below.
### Requirements
Well, [Docker](https://www.docker.com/).
And [NodeJS](https://nodejs.org/)
### Docker stuff
Pull the mysql image:
```cmd
docker pull mysql
```
Start the mysql container:
```cmd
docker run -p 3306:3306 -v C:/git/github/reactive-stack-js-mysql-poc/mysqlconf:/etc/mysql/conf.d -v C:/git/github/reactive-stack-js-mysql-poc/mysqlvolume:/var/lib/mysql --name mysql -e MYSQL_ROOT_PASSWORD=root -d mysql
```
__NOTE__: _Replace ```C:/git/github/reactive-stack-js-mysql-poc/``` with your folder path._
At this point, you can use your prefered MySQL GUI, like [HeidiSQL](https://www.heidisql.com/) for example.
Or you can use the console:
```cmd
docker exec -it mysql bash
```
Then:
```mysql
mysql -u root -p db2mirror
```
And use the password ```root```, or whatever you specified in the docker run command.
__NOTE__: _You will have to create db2mirror once, of course._
Run the following MySQL commands:
```mysql
CREATE USER 'root' IDENTIFIED BY 'root';
ALTER USER 'root' IDENTIFIED WITH mysql_native_password BY 'root';
flush privileges;
GRANT REPLICATION SLAVE ON *.* TO 'root';
CREATE DATABASE `db2mirror`;
CREATE TABLE `glob_locks` (
`GLOB_LOCK_ID` INT(11) NOT NULL,
`RES_NAME` VARCHAR(128),
`MESSAGE` MEDIUMTEXT,
PRIMARY KEY (`GLOB_LOCK_ID`) USING BTREE
);
```
Since we are mounting the volume in the above Docker run command, the above MySQL commands only need to be executed once.
### MySQL CDC
```cmd
yarn cdc
```
or
```cmd
node mysql.js
```
Then do something in your MySQL instance, create, modify or delete a row and you will see messages like those listed in the [out.mysql.events](out.mysql.events) file.
Enjoy :)
