EJS is a Javascript template library used to generate HTML strings from JSON data.

When using express to create a website, use the ejs template engine to create a basic website structure. The following is used in the current directory: the express-t ejs sophiehui command creates a subdirectory of sophiehui in the current directory, as shown in the following figure:

Wait until the execution ends.

View your first express application: npm start (use node app in the Command Prompt window. js), and then access http: // localhost: 3000/to see the effect of 2.
