    Comand line usage

    You can use this via the following command:

    replace-json-property pathToFile property value

    This command replaces all occurences of the matching property. It also replaces occurences in nested objects or objects in arrays.

    The following command would replace all values of the foo property with 'test' inside the test.json.

    replace-json-property ./test.json foo test,

    Executing the command above on the given JSON

        "foo": "bar",
        "a": {
            "b": 1,
            "foo": "bar",
            "c": [
                {"d": 1, "foo": "bar"},
                {"d": 2, "foo": "bar"},
                {"d": 3, "foo": "bar"},

    results in:

        "foo": "test",
       	"a": {
            "b": 1,
            "foo": "test",
            "c": [
                {"d": 1, "foo": "test"},
                {"d": 2, "foo": "test"},
                {"d": 3, "foo": "test"},

    Short form

    All commands explained above can also be run with the shortcut version rjp.

    rjp ./test.json foo test,

    Usage from code

    You can also use the replace function in your JavaScript code.

    1. Using module imports

      import {replace} from 'replace-json-property';
      replace('./environment/test.json', 'foo', 'new value');
    2. Using commonjs

      const replaceJSONProperty = require('replace-json-property');
      replaceJSONProperty.replace('./environment/test.json', 'foo', 'new value');
