Install

Using npm:

$ npm install core-installer

##1 Using Redis

1.1 Redis initialization

const {RedisInstaller} = require('core-installer');
const TARGET={};
//1. Single instance configuration
let config={
     // url:'redis://127.0.0.1:6379',
     host:'127.0.0.1',
     port:6379
}
const installer = new RedisInstaller(config,TARGET,false,true);
await installer. load();
//2. Multi-instance configuration
let config={
     APP1: {
         // url:'redis://127.0.0.1:6379',
         host:'127.0.0.1',
         port:6379
     },
     APP2: {
         host:'127.0.0.1',
         port:6379
     },
}
const installer = new RedisInstaller(config,TARGET,true,true);
await installer. load();

1.2 Redis usage

//1. Use in single mode
await TARGET.REDIS.SET('TEST:KEY','abc');
let result = await TARGET.REDIS.GET('TEST:KEY');
console. log(result);

//2, use in multi-instance mode
await TARGET.REDIS.APP1.SET('TEST:KEY:APP1','app1');
let result1 = await TARGET.REDIS.APP1.GET('TEST:KEY:APP1');
console.log(result1);

await TARGET.REDIS.APP2.SET('TEST:KEY:APP2','app2');
let result2 = await TARGET.REDIS.APP2.GET('TEST:KEY:APP2');
console.log(result2);

2 Using Mysql

2.1 Mysql initialization

const {MysqlInstaller} = require('core-installer');
const TARGET={};
//1. Single instance configuration
let config={
     host: "127.0.0.1",
     port: 3306,
     user: "root",
     password: "root12345",
     database: "test"
}
const installer = new MysqlInstaller(config,TARGET,false,true);
await installer. load();
//2. Multi-instance configuration
let config={
     APP1: {
         host: "127.0.0.1",
         port: 3306,
         user: "root",
         password: "root12345",
         database: "test"
     },
     APP2: {
         host: "127.0.0.1",
         port: 3306,
         user: "root",
         password: "root12345",
         database: "test"
     },
}
const installer = new MysqlInstaller(config,TARGET,true,true);
await installer. load();

2.2 Mysql use

//1. Use in single mode
let result = await TARGET.SQL('select * from test',[]);
console. log(result);
//2, use in multi-instance mode
let result1 = await TARGET.SQL.APP1('select * from test',[]);
console.log(result1);
let result2 = await TARGET.SQL.APP2('select * from test',[]);
console.log(result2);
