+# fast-safe-stringify
+
+Safe and fast serialization alternative to [JSON.stringify][].
+
+Gracefully handles circular structures instead of throwing in most cases.
+It could return an error string if the circular object is too complex to analyze,
+e.g. in case there are proxies involved.
+
+Provides a deterministic ("stable") version as well that will also gracefully
+handle circular structures. See the example below for further information.
+
+## Usage
+
+The same as [JSON.stringify][].
+
+`stringify(value[, replacer[, space[, options]]])`
+
+```js
+const safeStringify = require('fast-safe-stringify')
+const o = { a: 1 }
+o.o = o
+
+console.log(safeStringify(o))
+// '{"a":1,"o":"[Circular]"}'
+console.log(JSON.stringify(o))
+// TypeError: Converting circular structure to JSON
+
+function replacer(key, value) {
+  console.log('Key:', JSON.stringify(key), 'Value:', JSON.stringify(value))
+  // Remove the circular structure
+  if (value === '[Circular]') {
+    return
+  }
+  return value
+}
+
+// those are also defaults limits when no options object is passed into safeStringify
+// configure it to lower the limit.
+const options = {
+  depthLimit: Number.MAX_SAFE_INTEGER,
+  edgesLimit: Number.MAX_SAFE_INTEGER
+};
+
+const serialized = safeStringify(o, replacer, 2, options)
+// Key: "" Value: {"a":1,"o":"[Circular]"}
+// Key: "a" Value: 1
+// Key: "o" Value: "[Circular]"
+console.log(serialized)
+// {
+//  "a": 1
+// }
+```
+
+
+Using the deterministic version also works the same:
+
+```js
+const safeStringify = require('fast-safe-stringify')
+const o = { b: 1, a: 0 }
+o.o = o
+
+console.log(safeStringify(o))
+// '{"b":1,"a":0,"o":"[Circular]"}'
+console.log(safeStringify.stableStringify(o))
+// '{"a":0,"b":1,"o":"[Circular]"}'
+console.log(JSON.stringify(o))
+// TypeError: Converting circular structure to JSON
+```
+
+A faster and side-effect free implementation is available in the
+[safe-stable-stringify][] module. However it is still considered experimental
+due to a new and more complex implementation.
+
+### Replace strings constants
+
+- `[Circular]` - when same reference is found
+- `[...]` - when some limit from options object is reached
+
+## Differences to JSON.stringify
+
+In general the behavior is identical to [JSON.stringify][]. The [`replacer`][]
+and [`space`][] options are also available.
+
+A few exceptions exist to [JSON.stringify][] while using [`toJSON`][] or
+[`replacer`][]:
+
+### Regular safe stringify
+
+- Manipulating a circular structure of the passed in value in a `toJSON` or the
+  `replacer` is not possible! It is possible for any other value and property.
+
+- In case a circular structure is detected and the [`replacer`][] is used it
+  will receive the string `[Circular]` as the argument instead of the circular
+  object itself.
+
+### Deterministic ("stable") safe stringify
+
+- Manipulating the input object either in a [`toJSON`][] or the [`replacer`][]
+  function will not have any effect on the output. The output entirely relies on
+  the shape the input value had at the point passed to the stringify function!
+
+- In case a circular structure is detected and the [`replacer`][] is used it
+  will receive the string `[Circular]` as the argument instead of the circular
+  object itself.
+
+A side effect free variation without these limitations can be found as well
+([`safe-stable-stringify`][]). It is also faster than the current
+implementation. It is still considered experimental due to a new and more
+complex implementation.
+
+## Benchmarks
+
+Although not JSON, the Node.js `util.inspect` method can be used for similar
+purposes (e.g. logging) and also handles circular references.
+
+Here we compare `fast-safe-stringify` with some alternatives:
+(Lenovo T450s with a i7-5600U CPU using Node.js 8.9.4)
+
+```md
+fast-safe-stringify:   simple object x 1,121,497 ops/sec ±0.75% (97 runs sampled)
+fast-safe-stringify:   circular      x 560,126 ops/sec ±0.64% (96 runs sampled)
+fast-safe-stringify:   deep          x 32,472 ops/sec ±0.57% (95 runs sampled)
+fast-safe-stringify:   deep circular x 32,513 ops/sec ±0.80% (92 runs sampled)
+
+util.inspect:          simple object x 272,837 ops/sec ±1.48% (90 runs sampled)
+util.inspect:          circular      x 116,896 ops/sec ±1.19% (95 runs sampled)
+util.inspect:          deep          x 19,382 ops/sec ±0.66% (92 runs sampled)
+util.inspect:          deep circular x 18,717 ops/sec ±0.63% (96 runs sampled)
+
+json-stringify-safe:   simple object x 233,621 ops/sec ±0.97% (94 runs sampled)
+json-stringify-safe:   circular      x 110,409 ops/sec ±1.85% (95 runs sampled)
+json-stringify-safe:   deep          x 8,705 ops/sec ±0.87% (96 runs sampled)
+json-stringify-safe:   deep circular x 8,336 ops/sec ±2.20% (93 runs sampled)
+```
+
+For stable stringify comparisons, see the performance benchmarks in the
+[`safe-stable-stringify`][] readme.
+
+## Protip
+
+Whether `fast-safe-stringify` or alternatives are used: if the use case
+consists of deeply nested objects without circular references the following
+pattern will give best results.
+Shallow or one level nested objects on the other hand will slow down with it.
+It is entirely dependant on the use case.
+
+```js
+const stringify = require('fast-safe-stringify')
+
+function tryJSONStringify (obj) {
+  try { return JSON.stringify(obj) } catch (_) {}
+}
+
+const serializedString = tryJSONStringify(deep) || stringify(deep)
+```
