||||
Chain queries onto POJOs to return precise results.
|
||||
Chain queries onto arrays and arrays of objects to return precise results. See [example usages in the tests](./index.test.js) running on [this test data](./testdata.json).
|
||||
|
||||
## Usage
|
||||
|
||||
```javascript
|
||||
import Query from 'json-query-chain';
|
||||
|
||||
let myQ = new Query(someJsonData)
|
||||
let query = new Query(someJsonData)
|
||||
.search('isActiveUser', true)
|
||||
.results;
|
||||
|
||||
console.log('Results: ', query);
|
||||
```
|
||||
|
||||
### Chainable Methods
|
||||
|
||||
#### Search
|
||||
|
||||
Currently supports booleans and strings. (See [#1](https://github.com/sharpshark28/json-query-chain/issues/1) for Integer Support)
|
||||
|
||||
##### By Boolean
|
||||
|
||||
Acts as a smart filter returning only elements who's key matches the expected result.
|
||||
|
||||
```javascript
|
||||
.search('isActiveUser', true)
|
||||
.search(true, 'isActiveUser')
|
||||
```
|
||||
|
||||
##### By String
|
||||
|
||||
Sorts and filters out any elements in the array not matching the requested value while attempting to raise the best results to the top (most frequent number of occurrences).
|
||||
|
||||
```javascript
|
||||
.search('name', 'steele')
|
||||
.search('steele', 'name')
|
||||
```
|
||||
|
||||
#### Filter
|
||||
|
|
@ -42,30 +46,40 @@ Simpler version of search using a custom function in the chain.
|
|||
|
||||
##### By Key
|
||||
|
||||
Like `.filter()`, but narrowed down by key.
|
||||
|
||||
```javascript
|
||||
.filterBy('age', x => x >= 21)
|
||||
```
|
||||
|
||||
#### Sort
|
||||
|
||||
A chainable version of javascript's built in array sort.
|
||||
|
||||
```
|
||||
.sort((a, b) => a > b)
|
||||
```
|
||||
|
||||
##### By Boolean
|
||||
|
||||
Abstracted sort by matching a key to a boolean.
|
||||
|
||||
```javascript
|
||||
.sortBy('isActiveUser')
|
||||
```
|
||||
|
||||
##### By String
|
||||
|
||||
Sorts alphabetically based on key.
|
||||
|
||||
```javascript
|
||||
.sortBy('name')
|
||||
```
|
||||
|
||||
##### By Number
|
||||
|
||||
Sorts by ascending numerical order based on key.
|
||||
|
||||
```javascript
|
||||
.sortBy('netWorth')
|
||||
```
