[SOLVED] Why does setting the title of my powershell terminal not stick after other commands are run?

Why does setting the title of my powershell terminal not stick after other commands are run?

I have a powershell script that opens several powershell terminals and cd's into different directories and runs the applications in those directories:

start powershell @'
    $host.ui.RawUI.WindowTitle = \"application 1\"
    cd application1\backend
    npm install
    npm run build
    npm run start
'@

start powershell @'
    $host.ui.RawUI.WindowTitle = \"application 2\"
    cd application2\backend
    npm install
    npm run build
    npm run start
'@

start powershell @'
    $host.ui.RawUI.WindowTitle = \"application 3\"
    cd application3\backend
    npm install
    npm run build
    npm run start
'@

As you can see, the first thing I do for each terminal is set the title. However, the title gets replaced with each subsequent command. For example, for application1, I see "application 1" as the title but then "npm install" and then "npm run build" and then "npm run start".

How do I set the title so that it sticks? That is, I don't want the title changing to each subsequent command after setting it.

Note... I tried this:

start powershell @'
    cd application1\backend
    npm install
    npm run build
    npm run start
    $host.ui.RawUI.WindowTitle = \"application 1\"
'@

...hoping the title would stick since it would be the last command to run, but the terminal stays on npm run start because the application doesn't quit until I hit ctrl-c.

Is there another way to accomplish what I'm trying to do?

Thanks!

Solution

The trick is that I have to set the title in the application, not from the command line or the script. I had to add the line process.title = 'application 1'; to the application code.
