safe-json-parse

Parse JSON safely without throwing

Example (callback)

1var safeParse = require("safe-json-parse/callback")
2
3safeParse("{}", function (err, json) {
4    /* we have json */
5})
6
7safeparse("WRONG", function (err) {
8    /* we have err! */
9})

Example (tuple)

1var safeParse = require("safe-json-parse/tuple")
2
3var tuple1 = safeParse("{}")
4var json = tuple1[1] /* we have json */
5
6var tuple2 = safeparse("WRONG")
7var err = tuple2[0] /* we have err! */
8
9var tuple3 = safeParse(something)
10if (tuple3[0]) {
11    var err = tuple3[0]
12    // handle err
13} else {
14    var json = tuple3[1]
15    // handle json
16}

Example (result)

1var Result = require('rust-result')
2var safeParse = require('safe-json-parse/result')
3
4var result1 = safeParse("{}")
5var json = Result.Ok(result1) /* we have json */
6
7var result2 = safeparse("WRONG")
8var err = Result.Err(result2) /* we have err! */
9
10var result3 = safeParse(something)
11if (Result.isErr(result3)) {
12    var err = Result.Err(result3)
13    // handle err
14} else if (Result.isOk(result3)) {
15    var json = Result.Ok(result3)
16    // handle json
