A friend of mine asked a very good question “How can I use switch case statement in PUG using variable from route?” which took an hour time to figure it out! See the documentation for case statement here. I have a route like shown below
app.get("/", function (request, response) {
child = spawn('powershell.exe',
["C:\\projects\\caseDemo\\scripts\\DayOfWeek.ps1"])
child.stdout.on('data', function (data) {
var result = JSON.parse(data.toString())
response.render('index', {
DayOfWeek: result["DayOfWeek"].toString()
})
})
});
As usual we are calling the PS script which returns 6 as output. For our demo I can’t take the integer and render it on web page. So, I am converting to string and calling the variable DayOfWeek in case statement like shown below
Here is the PS snippet!
#region Day Script Get-Date | Select-Object DayOfWeek | ConvertTo-Json #endregion

p Saturday

The point here is no need to do some additional variable assignments like here! This breaks!
- var dummyVar = #{DayOfWeek}
- var dummyVar = DayOfWeek
Enjoy Pug!
