    @bugsnag/safe-json-stringify

    Build Status NPM Version

    This is a fork of safe-json-stringify with some opinionated changes, specifically for Bugsnag's use-case:

    • IE8 support. Our JS notifier supports IE8, so all of its dependencies must use IE8 compatible APIs.
    • A hard limit on object depth/breadth. Given a deep/wide enough data structure, the original version would run out of memory or stack allocations. Values are replaced with the string ... in such circumstances.
    • Doesn't replace repeated, but non-circular references (implemented by @MikeRalphson in their fork)
    • Adds the ability to apply key-based filters to specific subtrees

    Installation

    npm install @bugsnag/safe-json-stringify

    Usage

    The API is the same as JSON.stringify, with an additional options object:

    stringify(obj, [optional replacer], [optional spaces], [options])
    • options.redactedKeys: a list of keys whose value should be replaced with the string [REDACTED]. Keys can be strings for case insensitive matches, or regexes for partial or pattern matches. The array can contain a mixture of both.
    • options.redactedPaths: a list of paths where the redactedKeys option will be applied. The format of these strings are key names separated by . and if the property is an array, it is represented with []. For example: events.[].metaData.

    Example

    var stringify = require('@bugsnag/safe-json-stringify')
    stringify({
      api_key: 'd145b8e5afb56516423bc4d605e45442',
      events: [
        {
          errorMessage: 'Failed load tickets',
          errorClass: 'CheckoutError',
          user: {
            name: 'Jim Bug',
            email: 'jim@bugsnag.com',
            api_key: '245b39ebd3cd3992e85bffc81c045924'
          }
        }
      ]
    }, null, 2, {
      redactedKeys: [ 'api_key' ],
      redactedPaths: [ 'events.[].user' ]
    })
     
    // yields the following json:
    // {
    //   "api_key": "d145b8e5afb56516423bc4d605e45442",
    //   "events": [
    //     {
    //       "errorMessage": "Failed load tickets",
    //       "errorClass": "CheckoutError",
    //       "user": {
    //         "name": "Jim Bug",
    //         "email": "jim@bugsnag.com",
    //         "api_key": "[REDACTED]"
    //       }
    //     }
    //   ]
    // }
