In the process of a programmer taking on private work, it is crucial to master some useful tools and excellent open source projects. This issue brings you three excellent projects to help you find private work, allowing you to make money easily while improving your skills.

Open source e-commerce system CRMEB

A fan once confided to me that when doing outsourcing projects, the technology used was relatively old, and they were eager to improve their technical level by reading source code and secondary development. Open source e-commerce systems have extremely wide coverage from both the business and technical levels.

Business and technology highlights

1. Comprehensive business : covering the transaction process between buyers and sellers, product life cycle management, marketing strategy implementation, flash sale function under extreme concurrency, and payment services. Once you master its design ideas and technology stack, you can quickly adapt to 80% of the company's project needs.
2. Mainstream technology : The project has two versions, PHP and Java, and adopts a front-end and back-end separation design. The technology stack includes Spring Boot, Uni app, and MySQL. The framework uses MyBatis Plus, Redis for queuing and caching, Echarts for chart design, Spring Security for permission management, and the API interface follows the Restful style.

Actual operating effect

1. Management background : refreshing interface, large screen data statistics, and quick jump to various sub-modules. The left menu bar covers users, orders, products, distribution, finance and other functions. It is a complete e-commerce management backend.
2. Client : Developed using Uni app, H5, mini programs, and native apps have an excellent experience. The H5 end has a beautiful layout, including carousels, news briefings, commonly used functions, marketing sections, product rankings, etc. The interactive experience is similar to commonly used shopping applications and is very smooth to use.

Code structure and learning value

1. Clear code structure : After cloning locally, admin is the management front-end project, APP is the user-side front-end project, and CRMEB is the Java project (backend) that provides the interface. It is a Maven multi-module project. The enemy is responsible for the admin functional interface, common provides basic services, the front desk is responsible for the APP functional interface, surface provides service services, image stores pictures, shell has Linux system start and stop scripts, and the SQL folder stores SQL scripts.
2. Easy to learn and develop : supports Spring Profiles for environment isolation. Local debugging only needs to modify the database connection information to start quickly. You can learn a wealth of knowledge by exploring code of interest on the page, such as flash sales, product purchases, ordering processes, and more. This project is suitable for private work and can quickly create projects with background management functions. It supports multiple forms such as single entity, front-end and back-end separation, micro-services, and versions adapted to mobile phones. There are many secondary development projects, covering CMS systems, blogs, etc. It also includes popular Java technologies, such as Spring, Spring Boot, Spring Cloud, MyBatis, MyBatis Plus, permission control, scheduled tasks, code generators, etc.

Distributed scheduling computing framework Power Job

The new generation of Power Job is a powerful distributed scheduling and computing framework that can easily implement job scheduling and distributed computing of complex tasks.

Advantages of use

1. Simple and easy to use : It supports visual management and configuration through the web interface, and separates task planning and code logic.
2. Rich execution modes : It has 4 execution modes: single-chip, broadcast, Map, and MapReduce. Supports DAG orchestration between tasks, can configure task dependencies, and realize data transmission between tasks. 3. Superior performance : Compared with similar products such as XXL-Job, Power Job has superior performance in many product functions. In particular, the locking mechanism does not rely on database row-level locks and has stronger performance.
3. Diverse notification channels : Supports multiple notification channels such as WEBHOOK and DingTalk messages. Compared with XXL-Job, which can only send emails, notifications when tasks fail or are not executed are more timely. Many major manufacturers are using Power Job, and its stability is guaranteed.

For students who are interested in Server-Client architecture, data sharding, and distributed computing business, the Power Job source code is clear and easy to understand, making it a high-quality learning project.

I hope that through these three projects, everyone will go more and more smoothly on the road to technical improvement and personal affairs. If you have any insights or experiences on these projects, please share them in the comment area, and don’t forget to like and share them with more programmer friends in need! See you in the next video!
