jsonpath-complexity

Evaluate and summarize the complexity of a JSONPath expression using a simple heuristic.

Example

var jpc = require('jsonpath-complexity');
 
const complexity = jpc.complexity('$.a[(@.b + 1 == 5)][?(@.c && @d || !@.e || @.f)]')
// {
//   components : 4,
//  expressions : 2,
//        unary : 1,
//       binary : 2,
//      logical : 3
// }

Install

Install from npm:

$ npm install jsonpath-complexity

API

Returns a quantitative representation of path extression complexity. Value returned is object with summary of

• number of path components
• number of filter and script expressions
• number of unary operations
• number of binary operations (arithmatic and equivalency)
• number of logical operations (and/or)
