Easy to use Redis ORM based on node-redis
npm install metronomconst Model = require('metronom');
// create user model
// new Model(<model-schema>, <redis-key-prefix>, <model-options>)
const modelSchema = { // key: defaultValue
id: 0,
name: '',
age: 1,
job: {
name: 'teacher',
room: 12,
isManeger: false
},
tags: ['teacher', 'highschool', 'math']
},
const keyPrefix = 'users'; // default 'object'
const modelOptions = {
keyUnique: 'name', // this value must be in to the schema because metronom use it to create redis key like "users:12". Default value is object's created time
redisClientOptions: { /* node-redis configration */ }
flexSchema: false // if this value is true you cannot save a field outside the schema. Dafault value is false
}
// const userModel = new Model(modelSchema);
// const userModel = new Model(modelSchema, keyPrefix);
const userModel = new Model(modelSchema, keyPrefix, modelOptions);
const alice = await userModel.create({
name: 'alice',
age: 35
);
alice.age = 36;
await alice.save();
const response = await userModel.findById('alice');
console.log(response);
// {
// name: 'alice',
// age: 36,
// job: {
// name: 'teacher',
// room: 205,
// isManeger: true
// },
// tags:['teacher', 'highschool', 'music']
// }
await userModel.deleteById('alice');
