res node code example

Example 1: node js response header

response.setHeader("Content-Type", "text/html");

Example 2: nodejs response is html not json data

// use this after route not before route
if (process.env.NODE_ENV === 'production') {
  app.use(express.static(resolve(process.cwd(), 'client/build')))
  app.get('*', (req, res) => {
    res.sendFile(resolve(process.cwd(), 'client/build/index.html'))
  })
}
