@sentrie/json

The @sentrie/json module provides JSON validation utilities. For JSON parsing and stringification, use the @sentrie/js module.

Usage

use { isValid } from @sentrie/json

Functions

isValid(str: string): boolean

Validates whether a string is valid JSON.

Parameters:

• str - The JSON string to validate

Returns: true if the string is valid JSON, false otherwise

Example:

use { isValid } from @sentrie/json

let jsonStr = '{"name": "John", "age": 30}'
let isValid = json.isValid(jsonStr)  // true

let invalidStr = '{"name": "John", "age":}'
let isInvalid = json.isValid(invalidStr)  // false

JSON Parsing and Stringification

For JSON parsing and stringification, use the @sentrie/js module:

use { parse, stringify } from @sentrie/js as json

let obj = json.parse('{"name": "John", "age": 30}')
let str = json.stringify({"name": "John", "age": 30})

See the @sentrie/js documentation for more information.

Complete Example

namespace com/example/mypolicy

policy mypolicy {
  use { isValid } from @sentrie/json as jsonUtil
  use { parse, stringify } from @sentrie/js as json

  fact data!: string

  rule processData = default false {
    let isValid = jsonUtil.isValid(data)
    if isValid {
      let parsed = json.parse(data)
      let serialized = json.stringify(parsed)
      yield serialized != ""
    } else {
      yield false
    }
  }

  export decision of processData
}
