What is source-browser?

source-browser is a tool you run on your own computer to search product listings on a Chinese merchant platform called Liandong Xiaodian, sometimes written as "chain shop." It is built for people who already have a merchant account on that platform and want an easier local page to search, filter, and sort the products they can resell. After installing Node.js, you start the tool with a single command and open it in your browser at localhost port 3000. From there you log in with your Liandong Xiaodian merchant account. The README is explicit that a plain account is not enough: you need a registered merchant account with the shop feature actually activated, or the tool will not show any products after login. Once logged in, you can search by keyword, such as a product name, filter results to only show items currently available or already listed, filter by price range, and sort either by availability first or by price. You can also add blocked words to hide certain listings you do not want to see, and open a details link for any product. If you choose to search across all result pages instead of one page, the tool pulls every page before showing anything, so it only displays results if every page succeeds, and it can be slow with large result sets. On privacy, the project states it does not ship with any built in accounts, passwords, cookies, or tokens. Your login session is saved only on your own machine in a local data file, which is excluded from version control so it will not be committed or shared accidentally. The README also warns not to share that data folder, environment files, zip packages, or screenshots that reveal account or shop details when sharing the code. The project explicitly says it is for personal learning, research, and legitimate authorized use only, is not an official tool of the platform it connects to, and may stop working if that platform changes its login or interface. No license is listed in the README.
