Is there a way to detect screen size in node.js?-CodePudding

Specifically, I would like to make a GET request to a nodejs server, then get the number of monitors and their resolutions for the server.

E.g.

app.get('/screens', (req, res) => {
    //return the screen info for the computer running this express server
})

CodePudding user response：

With systeminformation package.

...
const si = require('systeminformation')

app.get('/screens', async(req, res, next) => {
  try {
    const {
      displays
    } = await si.graphics()

    if (!displays.length) {
      throw new Error('No displays')
    }

    res.json({
      displays: displays.length,
      x: displays[0].currentResX,
      y: displays[0].currentResY
    })
  } catch (err) {
    next(err)
  }
})
...

{ displays: 2, x: 1920, y: 1080 }
