A way for using custom build arguments

[cmaart]

Hi all,

is there a way to pass command line parameters to ionic serve or ionic build?
In my case I have the following setup:

• In package.json I have this script
  "build": ionic build

and i want to pass in parameters that I can use in my configs, like custom rollup config.
Example for planned usage from command line:

npm run build --stage=prod

Any help would be greatly appreciated!

We have not concept of custom parameters within the CLI. @danbucholtz I believe this is something that is more about how configs are used within app-scripts.

@cmaart,

Let me give this some thought and I'll get back to you in the coming days. This is lower priority for us so it may be a bit. You could certainly use Node environment variables in the interim.

Thanks,
Dan

@danbucholtz: Okay. What I currently do is, in the npm script i run a initializeBuildEnvironment.js script that take reads passed arguments (like initializeBuildEnvironment --stage:test), I store them as a json file and read the parameters from the json again later in the build process.

My use case if this is interesting for you why I even need it: We build for multiple stages. The build on the build agent should be able to pass in settings (like the stage) as a parameter to the npm script. In the custom webpack config I need the stage to replace endpoints according to the stage specified.

More than likely, we aren't going to have time to get to this in the next few months. With that in mind, I'm going to close this issue.

Thanks,
Dan

I used "yargs" for some like that

Or try to re the custom argv with. process.env.npm_config_argv Or process.env.argv

@alan-agius4: Thx! That's pretty much what I ended up doing. I just set env variables according to my stage that i'm building for
