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
|
1 2 3 4 5 6 7 8 9 10 |
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!
|
1 2 3 |
#region Day Script Get-Date | Select-Object DayOfWeek | ConvertTo-Json #endregion |
CASE STATEMENT IN PUG

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
<!DOCTYPE html> html(lang="en") head meta(charset="UTF-8") meta(name="viewport", content="width=device-width, initial-scale=1.0") meta(http-equiv="X-UA-Compatible", content="ie=edge") title Chen V style. h1 { font-family: 'Goudy Old Style'; text-align: center; } body hr h1 Swtich Case Demo hr case DayOfWeek when '1' p Monday when '2' p Tuesday when '3' p Wednesday when '4' p Thursday when '5' p Friday when '6' p Saturday when '7' p Sunday default p Nothing |
The point here is no need to do some additional variable assignments like here! This breaks!

1 2 |
- var dummyVar = #{DayOfWeek} - var dummyVar = DayOfWeek |
Enjoy Pug!
