Why I Developed JianChuan

During one of my work sessions, I needed to send some files to another computer. That computer had nothing installed except a web browser. There were many possible ways to transfer the files, such as shared folders, DingTalk, QQ, WeChat, or a USB drive. However, each option came with inconveniences: some required configuration, others required downloading additional software, and USB drives involved repeatedly copying files back and forth. Even after installing the software, account login was often required. Services like QQ and WeChat are relatively private, and I did not want to log into my personal accounts on another computer. Logging into DingTalk or WeCom could also force me to log out of my own device, making the whole process unnecessarily troublesome. So I wondered whether I could create a lightweight tool that only needed to be installed on my own computer for sending files, while any other device could access shared content directly through a browser without installing a client. Later, by chance, I discovered electron-egg and found that it met most of my requirements. So I started developing it. After implementing the basic features, I found that it worked quite well. And that is how JianChuan came into existence.

5. Tech Stack

Software Architecture

Built with electron-egg + uniapp + primevue ui.

Installation Guide

1. Installation: npm i

2. Preview: npm run start

3. During development, the frontend is a standalone uniapp project that needs to be opened and launched using HBuilderX. The project is located in the frontend directory. After building and publishing it as H5, run npm run rd in the project root directory to place the compiled files into electron-egg.

4. There are some packaging issues under linux-arm. You need to use the locally installed fpm. Please refer to the tutorial in the official documentation.
