I follow the teaching video at this stage to do a front-end node project (I don"t know much about node). I am responsible for the implementation of the front-end page and interface development.
Environment deployment:
1. Node.js and npm
2 are installed. Downloaded the project source code
3. Installed the required dependency package
4. Imported the database and changed the database password
problem: when the npm start Times error 404, the front-end static page interface ajax request also reported an error 404. Localhost3000page shows no information
1. Why did this happen? Is it because my environment is not ready yet? Or does the project itself do not have this file? Please give me
