JSON Find and Replace
If you've ever wanted to perform find/replace operations on JSON data structures, jafar is for you! Find and replace keys and values using a regex-based set of methods that allow you to easily transform JSON while preserving the structure. No more awful stringifying/regexing/parsing steps!
Initialization
Instantiate an instance of jafar with either a reference to a .json file or an actual JSON structure:
var jafar = new Jafar({
json: './test/sample.json'
});
// or:
var jafar = new Jafar({
json: {
"thing": {
"another": "somethingsomething"
},
"thing2": {
"another2": "something2"
},
"thing3": {
"thing4": {
"thing5thing5": "something3"
}
}
}
});
jafar
will be instantiated with a json
property, which will be transformed when
performing find/replace operations:
jafar.json
Methods
jafar.listAllKeys()
Recurses over jafar.json
and returns an array of all keys within the JSON.
jafar.findKey(key)
Returns the index of key
as it exists within the array returned by listAllKeys()
.
jafar.replaceKey(keyToFind, replacementKey, isExact, isGlobal)
Recurses over jafar.json
and transforms the JSON, replacing keyToFind
with
replacementKey
.
If isExact
is true, the keyToFind
must be an exact match in order to be replaced.
If isGlobal
is true, the keyToFind
will be replaced as many times as it exists
per key (that is, the g
RegEx flag will be used).
Note that this method will transform jafar.json
into entirely new JSON.
jafar.listAllValues()
Recurses over jafar.json
and returns an array of all values within the JSON.
jafar.findValue(value)
Returns the index of value
as it exists within the array returned by listAllValues()
.
jafar.replaceValue(valueToFind, replacementValue, isExact, isGlobal)
Recurses over jafar.json
and transforms the JSON, replacing valueToFind
with
replacementValue
.
If isExact
is true, the valueToFind
must be an exact match in order to be replaced.
If isGlobal
is true, the valueToFind
will be replaced as many times as it exists
per value (that is, the g
RegEx flag will be used).
Note that this method will transform jafar.json
into entirely new JSON.
