Say you want to fetch some data at regular intervals into your project and this data is to be fetched from external APIs, use this application to create/schedule cron jobs and save data to ur database (i used mongo here)

classDiagram
    class apiSchema {
        _id: ObjectId
        appId: ObjectId
        apiName: String
        apiRoute: String
        requestType: String
        queryParams: Mixed
        headerParams: Mixed
        payload: Mixed
        isActive: Boolean
        frequency: String
        triggerTime: Date
        cronExpression: String
        history: Array
        createdAt: Date
        appName: String
        description: String
        rootPath: String
    }

    class applicationSchema {
        _id: ObjectId
        appName: String
        description: String
        rootPath: String
        apiList: Array
        auth: Object
    }

    apiSchema *-- applicationSchema : appId

• 2 schemas Application and API where we store application and api data respectively
• Each application contains a list of APIs which are cron jobs to be targetted
• 2 ways to run the jobs, Automatic or Manual. frequency field in APIs help us differentiate this. If 'Instant', its manual else the later
• If the server restarts, we'll pick up from where we left off by checking the isActive status

1. npm i
2. npm run dev: for running locally (nodemon enabled)
3. npm start for production

1. Create a .env file at the root and initialize all variables you'll need from config.js
2. Example securityKey: process.env.NODE_APP_SECURITY_KEY you will make an entry in .env called NODE_APP_SECURITY_KEY: XYZ

• Be nice, create a PR and I'll review them
