get json values quickly

- -GJSON is a Go package that provides a [fast](#performance) and [simple](#get-a-value) way to get values from a json document. -It has features such as [one line retrieval](#get-a-value), [dot notation paths](#path-syntax), [iteration](#iterate-through-an-object-or-array), and [parsing json lines](#json-lines). - -Also check out [SJSON](https://github.com/tidwall/sjson) for modifying json, and the [JJ](https://github.com/tidwall/jj) command line tool. - -Getting Started -=============== - -## Installing - -To start using GJSON, install Go and run `go get`: - -```sh -$ go get -u github.com/tidwall/gjson -``` - -This will retrieve the library. - -## Get a value -Get searches json for the specified path. A path is in dot syntax, such as "name.last" or "age". When the value is found it's returned immediately. - -```go -package main - -import "github.com/tidwall/gjson" - -const json = `{"name":{"first":"Janet","last":"Prichard"},"age":47}` - -func main() { - value := gjson.Get(json, "name.last") - println(value.String()) -} -``` - -This will print: - -``` -Prichard -``` -*There's also the [GetMany](#get-multiple-values-at-once) function to get multiple values at once, and [GetBytes](#working-with-bytes) for working with JSON byte slices.* - -## Path Syntax - -Below is a quick overview of the path syntax, for more complete information please -check out [GJSON Syntax](SYNTAX.md). - -A path is a series of keys separated by a dot. -A key may contain special wildcard characters '\*' and '?'. -To access an array value use the index as the key. -To get the number of elements in an array or to access a child path, use the '#' character. -The dot and wildcard characters can be escaped with '\\'. - -```json -{ - "name": {"first": "Tom", "last": "Anderson"}, - "age":37, - "children": ["Sara","Alex","Jack"], - "fav.movie": "Deer Hunter", - "friends": [ - {"first": "Dale", "last": "Murphy", "age": 44, "nets": ["ig", "fb", "tw"]}, - {"first": "Roger", "last": "Craig", "age": 68, "nets": ["fb", "tw"]}, - {"first": "Jane", "last": "Murphy", "age": 47, "nets": ["ig", "tw"]} - ] -} -``` -``` -"name.last" >> "Anderson" -"age" >> 37 -"children" >> ["Sara","Alex","Jack"] -"children.#" >> 3 -"children.1" >> "Alex" -"child*.2" >> "Jack" -"c?ildren.0" >> "Sara" -"fav\.movie" >> "Deer Hunter" -"friends.#.first" >> ["Dale","Roger","Jane"] -"friends.1.last" >> "Craig" -``` - -You can also query an array for the first match by using `#(...)`, or find all -matches with `#(...)#`. Queries support the `==`, `!=`, `<`, `<=`, `>`, `>=` -comparison operators and the simple pattern matching `%` (like) and `!%` -(not like) operators. - -``` -friends.#(last=="Murphy").first >> "Dale" -friends.#(last=="Murphy")#.first >> ["Dale","Jane"] -friends.#(age>45)#.last >> ["Craig","Murphy"] -friends.#(first%"D*").last >> "Murphy" -friends.#(first!%"D*").last >> "Craig" -friends.#(nets.#(=="fb"))#.first >> ["Dale","Roger"] -``` - -*Please note that prior to v1.3.0, queries used the `#[...]` brackets. This was -changed in v1.3.0 as to avoid confusion with the new -[multipath](SYNTAX.md#multipaths) syntax. For backwards compatibility, -`#[...]` will continue to work until the next major release.* - -## Result Type - -GJSON supports the json types `string`, `number`, `bool`, and `null`. -Arrays and Objects are returned as their raw json types. - -The `Result` type holds one of these: - -``` -bool, for JSON booleans -float64, for JSON numbers -string, for JSON string literals -nil, for JSON null -``` - -To directly access the value: - -```go -result.Type // can be String, Number, True, False, Null, or JSON -result.Str // holds the string -result.Num // holds the float64 number -result.Raw // holds the raw json -result.Index // index of raw value in original json, zero means index unknown -``` - -There are a variety of handy functions that work on a result: - -```go -result.Exists() bool -result.Value() interface{} -result.Int() int64 -result.Uint() uint64 -result.Float() float64 -result.String() string -result.Bool() bool -result.Time() time.Time -result.Array() []gjson.Result -result.Map() map[string]gjson.Result -result.Get(path string) Result -result.ForEach(iterator func(key, value Result) bool) -result.Less(token Result, caseSensitive bool) bool -``` - -The `result.Value()` function returns an `interface{}` which requires type assertion and is one of the following Go types: - -The `result.Array()` function returns back an array of values. -If the result represents a non-existent value, then an empty array will be returned. -If the result is not a JSON array, the return value will be an array containing one result. - -```go -boolean >> bool -number >> float64 -string >> string -null >> nil -array >> []interface{} -object >> map[string]interface{} -``` - -### 64-bit integers - -The `result.Int()` and `result.Uint()` calls are capable of reading all 64 bits, allowing for large JSON integers. - -```go -result.Int() int64 // -9223372036854775808 to 9223372036854775807 -result.Uint() int64 // 0 to 18446744073709551615 -``` - -## Modifiers and path chaining - -New in version 1.2 is support for modifier functions and path chaining. - -A modifier is a path component that performs custom processing on the -json. - -Multiple paths can be "chained" together using the pipe character. -This is useful for getting results from a modified query. - -For example, using the built-in `@reverse` modifier on the above json document, -we'll get `children` array and reverse the order: - -``` -"children|@reverse" >> ["Jack","Alex","Sara"] -"children|@reverse|0" >> "Jack" -``` - -There are currently the following built-in modifiers: - -- `@reverse`: Reverse an array or the members of an object. -- `@ugly`: Remove all whitespace from a json document. -- `@pretty`: Make the json document more human readable. -- `@this`: Returns the current element. It can be used to retrieve the root element. -- `@valid`: Ensure the json document is valid. -- `@flatten`: Flattens an array. -- `@join`: Joins multiple objects into a single object. - -### Modifier arguments - -A modifier may accept an optional argument. The argument can be a valid JSON -document or just characters. - -For example, the `@pretty` modifier takes a json object as its argument. - -``` -@pretty:{"sortKeys":true} -``` - -Which makes the json pretty and orders all of its keys. - -```json -{ - "age":37, - "children": ["Sara","Alex","Jack"], - "fav.movie": "Deer Hunter", - "friends": [ - {"age": 44, "first": "Dale", "last": "Murphy"}, - {"age": 68, "first": "Roger", "last": "Craig"}, - {"age": 47, "first": "Jane", "last": "Murphy"} - ], - "name": {"first": "Tom", "last": "Anderson"} -} -``` - -*The full list of `@pretty` options are `sortKeys`, `indent`, `prefix`, and `width`. -Please see [Pretty Options](https://github.com/tidwall/pretty#customized-output) for more information.* - -### Custom modifiers - -You can also add custom modifiers. - -For example, here we create a modifier that makes the entire json document upper -or lower case. - -```go -gjson.AddModifier("case", func(json, arg string) string { - if arg == "upper" { - return strings.ToUpper(json) - } - if arg == "lower" { - return strings.ToLower(json) - } - return json -}) -``` - -``` -"children|@case:upper" >> ["SARA","ALEX","JACK"] -"children|@case:lower|@reverse" >> ["jack","alex","sara"] -``` - -## JSON Lines - -There's support for [JSON Lines](http://jsonlines.org/) using the `..` prefix, which treats a multilined document as an array. - -For example: - -``` -{"name": "Gilbert", "age": 61} -{"name": "Alexa", "age": 34} -{"name": "May", "age": 57} -{"name": "Deloise", "age": 44} -``` - -``` -..# >> 4 -..1 >> {"name": "Alexa", "age": 34} -..3 >> {"name": "Deloise", "age": 44} -..#.name >> ["Gilbert","Alexa","May","Deloise"] -..#(name="May").age >> 57 -``` - -The `ForEachLines` function will iterate through JSON lines. - -```go -gjson.ForEachLine(json, func(line gjson.Result) bool{ - println(line.String()) - return true -}) -``` - -## Get nested array values - -Suppose you want all the last names from the following json: - -```json -{ - "programmers": [ - { - "firstName": "Janet", - "lastName": "McLaughlin", - }, { - "firstName": "Elliotte", - "lastName": "Hunter", - }, { - "firstName": "Jason", - "lastName": "Harold", - } - ] -} -``` - -You would use the path "programmers.#.lastName" like such: - -```go -result := gjson.Get(json, "programmers.#.lastName") -for _, name := range result.Array() { - println(name.String()) -} -``` - -You can also query an object inside an array: - -```go -name := gjson.Get(json, `programmers.#(lastName="Hunter").firstName`) -println(name.String()) // prints "Elliotte" -``` - -## Iterate through an object or array - -The `ForEach` function allows for quickly iterating through an object or array. -The key and value are passed to the iterator function for objects. -Only the value is passed for arrays. -Returning `false` from an iterator will stop iteration. - -```go -result := gjson.Get(json, "programmers") -result.ForEach(func(key, value gjson.Result) bool { - println(value.String()) - return true // keep iterating -}) -``` - -## Simple Parse and Get - -There's a `Parse(json)` function that will do a simple parse, and `result.Get(path)` that will search a result. - -For example, all of these will return the same result: - -```go -gjson.Parse(json).Get("name").Get("last") -gjson.Get(json, "name").Get("last") -gjson.Get(json, "name.last") -``` - -## Check for the existence of a value - -Sometimes you just want to know if a value exists. - -```go -value := gjson.Get(json, "name.last") -if !value.Exists() { - println("no last name") -} else { - println(value.String()) -} - -// Or as one step -if gjson.Get(json, "name.last").Exists() { - println("has a last name") -} -``` - -## Validate JSON - -The `Get*` and `Parse*` functions expects that the json is well-formed. Bad json will not panic, but it may return back unexpected results. - -If you are consuming JSON from an unpredictable source then you may want to validate prior to using GJSON. - -```go -if !gjson.Valid(json) { - return errors.New("invalid json") -} -value := gjson.Get(json, "name.last") -``` - -## Unmarshal to a map - -To unmarshal to a `map[string]interface{}`: - -```go -m, ok := gjson.Parse(json).Value().(map[string]interface{}) -if !ok { - // not a map -} -``` - -## Working with Bytes - -If your JSON is contained in a `[]byte` slice, there's the [GetBytes](https://godoc.org/github.com/tidwall/gjson#GetBytes) function. This is preferred over `Get(string(data), path)`. - -```go -var json []byte = ... -result := gjson.GetBytes(json, path) -``` - -If you are using the `gjson.GetBytes(json, path)` function and you want to avoid converting `result.Raw` to a `[]byte`, then you can use this pattern: - -```go -var json []byte = ... -result := gjson.GetBytes(json, path) -var raw []byte -if result.Index > 0 { - raw = json[result.Index:result.Index+len(result.Raw)] -} else { - raw = []byte(result.Raw) -} -``` - -This is a best-effort no allocation sub slice of the original json. This method utilizes the `result.Index` field, which is the position of the raw data in the original json. It's possible that the value of `result.Index` equals zero, in which case the `result.Raw` is converted to a `[]byte`. - -## Get multiple values at once - -The `GetMany` function can be used to get multiple values at the same time. - -```go -results := gjson.GetMany(json, "name.first", "name.last", "age") -``` - -The return value is a `[]Result`, which will always contain exactly the same number of items as the input paths. - -## Performance -

-### Escape character - -Special purpose characters, such as `.`, `*`, and `?` can be escaped with `\`. - -```go -fav\.movie "Deer Hunter" -``` - -### Arrays - -The `#` character allows for digging into JSON Arrays. - -To get the length of an array you'll just use the `#` all by itself. - -```go -friends.# 3 -friends.#.age [44,68,47] -``` - -### Queries - -You can also query an array for the first match by using `#(...)`, or find all matches with `#(...)#`. -Queries support the `==`, `!=`, `<`, `<=`, `>`, `>=` comparison operators, -and the simple pattern matching `%` (like) and `!%` (not like) operators. -

-To query for a non-object value in an array, you can forgo the string to the right of the operator. - -```go -children.#(!%"*a*") "Alex" -children.#(%"*a*")# ["Sara","Jack"] -``` - -Nested queries are allowed. - -```go -friends.#(nets.#(=="fb"))#.first >> ["Dale","Roger"] -``` - -*Please note that prior to v1.3.0, queries used the `#[...]` brackets. This was -changed in v1.3.0 as to avoid confusion with the new [multipath](#multipaths) -syntax. For backwards compatibility, `#[...]` will continue to work until the -next major release.* - -### Dot vs Pipe - -The `.` is standard separator, but it's also possible to use a `|`. -In most cases they both end up returning the same results. -The cases where`|` differs from `.` is when it's used after the `#` for [Arrays](#arrays) and [Queries](#queries). - -Here are some examples - -```go -friends.0.first "Dale" -friends|0.first "Dale" -friends.0|first "Dale" -friends|0|first "Dale" -friends|# 3 -friends.# 3 -friends.#(last="Murphy")# [{"first": "Dale", "last": "Murphy", "age": 44},{"first": "Jane", "last": "Murphy", "age": 47}] -friends.#(last="Murphy")#.first ["Dale","Jane"] -friends.#(last="Murphy")#|first -friends.#(last="Murphy")#.0 [] -friends.#(last="Murphy")#|0 {"first": "Dale", "last": "Murphy", "age": 44} -friends.#(last="Murphy")#.# [] -friends.#(last="Murphy")#|# 2 -``` - -Let's break down a few of these. - -The path `friends.#(last="Murphy")#` all by itself results in - -```json -[{"first": "Dale", "last": "Murphy", "age": 44},{"first": "Jane", "last": "Murphy", "age": 47}] -``` - -The `.first` suffix will process the `first` path on each array element *before* returning the results. Which becomes - -```json -["Dale","Jane"] -``` - -But the `|first` suffix actually processes the `first` path *after* the previous result. -Since the previous result is an array, not an object, it's not possible to process -because `first` does not exist. - -Yet, `|0` suffix returns - -```json -{"first": "Dale", "last": "Murphy", "age": 44} -``` - -Because `0` is the first index of the previous result. - -### Modifiers - -A modifier is a path component that performs custom processing on the JSON. - -For example, using the built-in `@reverse` modifier on the above JSON payload will reverse the `children` array: - -```go -children.@reverse ["Jack","Alex","Sara"] -children.@reverse.0 "Jack" -``` - -There are currently the following built-in modifiers: - -- `@reverse`: Reverse an array or the members of an object. -- `@ugly`: Remove all whitespace from JSON. -- `@pretty`: Make the JSON more human readable. -- `@this`: Returns the current element.
