Modify action for json files

[adrianmroz]

My proposition is to add a modify action for JSON files, where you will provide callback instead of pattern and template. In callback you would get JSON.parsed object and you should also return POJsO which will be JSON.stringifyd and written to file.

I went ahead and made a custom action for this, but I definitely think this could get rolled in as a flag on modify action types or a new action type altogether. Here's the code for alterJsonAction.js: https://gist.github.com/wbobeirne/63e1b8c3a16ffce6dac5c7d81afd5cec?ts=2

Example usage from my use case is:

const alterJsonAction = require("alterJsonAction");

actions: [alterJsonAction({
    path: "../webpack/entries.json",
    alter: (json, data) => {
        const name = snakeCase(data.name);
        json[data.platform][name] = `pages/${name}`;
        return json;
    },
})],

I also threw in an indentation arg there that takes an int or "\t", if 2 spaces ain't your game.

sorry for the late response, I agree that this would be pretty useful in some cases. I'll have to give some more thought to the best implementation for this feature. Thanks!

hey, with plop 1.8.0 you can now create custom action types that you can share with other projects :-)

I created a custom action type to add data to my config.json file.
Tried to follow the plop style to keep it customizable.

nice! You could publish this out as an NPM module that others can use via plop.load(). If you want to do that and need help, let me know.

[mritzco]

I'll happily do! Just publish to npm or any specific requirements?

Sorry for the delay on this response. You can look at this repo as a guide to how this is done. I'm going to try to get more instructional content together soon.

@amwmedia
Ok, that took a bit longer than expected:

Could you please take a look at this repo and let me know if that would do.

Original method gets the config on the method call, while the load method passes the config on the require function. It's working with the testing file but I'm not sure it will work properly in all cases.
