About codic

Codic uses Activities and Tasks to let you automate processes in your app.

A task is what you want to do at a particular time. It can be a simple function or a file exporting a function.

Activity specifies the time and how often one or more tasks are run. It can run one or more tasks, it can be updated at runtime.

You can store the tasks and activities using any database through its drivers interface. codic-redis is a driver implementation for redis database.

Installation

Install codic and codic-redis.

npm install --save codic codic-redis

or

yarn add codic codic-redis

Release Info

codic-redis is now version 2, with typescript support just like codic. Note: your app does not have to be in typescript to use the library.

Usage

In your code, do the following:

1import Codic from "codic";
2import RedisDriver from "codic-redis";
3
4//instatiate redis driver and codic
5var driver = new RedisDriver();
6var codic = new Codic(driver);
7
8// define your tasks
9const simpleLogTask = (activity) => {
10    console.log("Simply saying "+activity.attrs.data.message);
11}
12// use an IIFE, to create database activities
13(async function(){
14
15    try {
16        // register task on Codic
17        await codic.assign("log something",{},simpleLogTask);
18
19        //create the activities that run the tasks
20        await codic
21            .run("log something")
22            .every(3) //3 seconds
23            .use({ message: "Hello" }) //pass data to task
24            .save();
25
26        //start codic
27        await codic.start();
28    } catch (error) {
29    console.log(error);
30  }
31})();

Thats it. You are live!!

Remember to start your redis server for this to work.

Configuring redis Connection

codic-redis uses ioredis under the hood. You would configure it the same way you configure ioredis. ioredis is a robust, performance-focused and full-featured Redis client for Node.js.

On instantiation, pass your configuration object to the RedisDriver like below:

1
2var driver = new RedisDriver({
3  port: 6379,          // Redis port
4  host: '127.0.0.1',   // Redis host
5  family: 4,           // 4 (IPv4) or 6 (IPv6)
6  password: 'auth',
7  db: 0
8});
9

Once this is running, you have access to the underlying ioredis object via

driver.db

All of ioredis actions can be performed on the driver.db object. You can follow the ioredis documentation here.

Configuring redis server

Redis requires a server to be running on your host computer. It is recommended that you use redis version >4.0.0.

Linux users can download it from their package manager though that might be out of date.

Make sure your redis server is running on the same port as you specify in the redis configuration above.
