safe-json-parse

Parse JSON safely without throwing

Example (callback)

var safeParse = require("safe-json-parse/callback")

safeParse("{}", function (err, json) {
    /* we have json */
})

safeparse("WRONG", function (err) {
    /* we have err! */
})

Example (tuple)

var safeParse = require("safe-json-parse/tuple")

var tuple1 = safeParse("{}")
var json = tuple1[1] /* we have json */

var tuple2 = safeparse("WRONG")
var err = tuple2[0] /* we have err! */

var tuple3 = safeParse(something)
if (tuple3[0]) {
    var err = tuple3[0]
    // handle err
} else {
    var json = tuple3[1]
    // handle json
}

Example (result)

var Result = require('rust-result')
var safeParse = require('safe-json-parse/result')

var result1 = safeParse("{}")
var json = Result.Ok(result1) /* we have json */

var result2 = safeparse("WRONG")
var err = Result.Err(result2) /* we have err! */

var result3 = safeParse(something)
if (Result.ifErr(result3)) {
    var err = Result.Err(result3)
    // handle err
} else if (Result.ifOk(result3)) {
    var json = Result.Ok(result3)
    // handle json
}

Other packages similar to safe-json-parse

json-parse-safe

The json-parse-safe package provides a similar functionality by safely parsing JSON strings and returning a default value or an error object if the JSON is malformed. It is comparable to safe-json-parse in terms of error handling and default value support.

json5

The json5 package allows for more lenient JSON parsing, supporting a superset of JSON that includes additional features like comments and trailing commas. While it provides safe parsing, it is more feature-rich compared to safe-json-parse.

fast-json-parse

The fast-json-parse package focuses on performance and provides a fast way to parse JSON strings safely. It includes error handling similar to safe-json-parse but is optimized for speed.
