Getting version from package.json

I'm using appveyor to build a node app. Some of the artifacts produced have the version number (specified in my package.json file) in their name. So I'd like to be able to get the version number out of the package.json file into a environment variable. I know I could write some powershell without too much trouble, but I was wondering if there was a first class way of doing this? Does appveyor understand package.json?

   It's not supported out-of-the-box, so PowerShell is your option :)

   Thanks. For anyone coming along later, you can do it like this:

   (Get-Content -Raw -Path package.json | ConvertFrom-Json).version

   Tried this but didn't work:

   init:
     - git config --global core.autocrlf true
     - ps: $env:package_version = (Get-Content -Raw -Path package.json | ConvertFrom-Json).version

   version: $(package_version)-{build}

   Hi Kosmas,

   init scrips happens before clone, therefore package.json is not available at that moment. Also you have to update build details with API, if you need to do it during the build. Please try the following at install stage:

   install:
    - ps: $env:package_version = (Get-Content -Raw -Path package.json | ConvertFrom-Json).version
    - ps: Update-AppveyorBuild -Version "$(package_version)-$env:APPVEYOR_BUILD_NUMBER"
   

   Let us know if this helps.

   --ilya.

   It had to be $env:package_version isntead of $(package_version), thanks!

   install:
     - ps: $env:package_version = (Get-Content -Raw -Path package.json | ConvertFrom-Json).version
     - ps: Update-AppveyorBuild -Version "$env:package_version-$env:APPVEYOR_BUILD_NUMBER"

   So, based on the above I have the following line in the 'Install script' section of the Environment configuration page:
   PowerShell (Get-Content -Raw -Path package.json | ConvertFrom-JSON).version

   I'm getting an error stating "'ConvertFrom-JSON' is not recognized as an internal or external command".

   I've confirmed that we're using PS v5.
   What am I missing?
   Thanks

   branches:

     only:

     - master

   init:

   - cmd: PowerShell Install-Product node 7.2.1

   install:

   - cmd: "PowerShell $env:package_version = (Get-Content -Raw -Path package.json | ConvertFrom-JSON).version \necho %$env:package_version%\n\nUpdate-AppveyorBuild -Version \"$($env.package_version)\"\n\nnpm install"

   build_script:

   - cmd: >-

       set NODE_ENV=development

    

       npm run build

    

       7z a nexus-client-dev.zip @deploy-package.txt

   test: off

   artifacts:

   - path: nexus-client-dev.zip

     name: nexus-client-dev

    

   Above is the exported yaml.

    

    

   Thanks

    If you run PowerShell (Get-Content -Raw -Path package.json | ConvertFrom-JSON).version on your local Windows machine in command prompt, you will get the same result. If you run PowerShell "(Get-Content -Raw -Path package.json | ConvertFrom-JSON).version" (see quotes added), you will get expected results (provided you have package.json in the current directory.

    Additional notes:

    • not sure if next line with %% will work, it is CMD environment variable notation, not PowerShell
    • not sure why you need to run this in CMD mode at all. It can be easily called in PS mode without calling PowerShell explicitly, as in previous examples in this thread.
