+
+A set of utilities that extend the use of JSON. Designed to be fast and memory efficient
+
+Features:
+
+- [x] `parseChunked()` – Parse JSON that comes by chunks (e.g. FS readable stream or fetch response stream)
+- [x] `stringifyStream()` – Stringify stream (Node.js)
+- [x] `stringifyInfo()` – Get estimated size and other facts of JSON.stringify() without converting a value to string
+- [ ] **TBD** Support for circular references
+- [ ] **TBD** Binary representation [branch](https://github.com/discoveryjs/json-ext/tree/binary)
+- [ ] **TBD** WHATWG [Streams](https://streams.spec.whatwg.org/) support
+
+## Install
+
+```bash
+npm install @discoveryjs/json-ext
+```
+
+## API
+
+- [parseChunked(chunkEmitter)](#parsechunkedchunkemitter)
+- [stringifyStream(value[, replacer[, space]])](#stringifystreamvalue-replacer-space)
+- [stringifyInfo(value[, replacer[, space[, options]]])](#stringifyinfovalue-replacer-space-options)
+    - [Options](#options)
+        - [async](#async)
+        - [continueOnCircular](#continueoncircular)
+- [version](#version)
+
+### parseChunked(chunkEmitter)
+
+Works the same as [`JSON.parse()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse) but takes `chunkEmitter` instead of string and returns [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
+
+> NOTE: `reviver` parameter is not supported yet, but will be added in next releases.
+> NOTE: WHATWG streams aren't supported yet
+
+When to use:
+- It's required to avoid freezing the main thread during big JSON parsing, since this process can be distributed in time
+- Huge JSON needs to be parsed (e.g. >500MB on Node.js)
+- Needed to reduce memory pressure. `JSON.parse()` needs to receive the entire JSON before parsing it. With `parseChunked()` you may parse JSON as first bytes of it comes. This approach helps to avoid storing a huge string in the memory at a single time point and following GC.
+
+[Benchmark](https://github.com/discoveryjs/json-ext/tree/master/benchmarks#parse-chunked)
+
+Usage:
+
+```js
+const { parseChunked } = require('@discoveryjs/json-ext');
+
+// as a regular Promise
+parseChunked(chunkEmitter)
+    .then(data => {
+        /* data is parsed JSON */
+    });
+
+// using await (keep in mind that not every runtime has a support for top level await)
+const data = await parseChunked(chunkEmitter);
+```
+
+Parameter `chunkEmitter` can be:
+- [`ReadableStream`](https://nodejs.org/dist/latest-v14.x/docs/api/stream.html#stream_readable_streams) (Node.js only)
+```js
+const fs = require('fs');
+const { parseChunked } = require('@discoveryjs/json-ext');
+
+parseChunked(fs.createReadStream('path/to/file.json'))
+```
+- Generator, async generator or function that returns iterable (chunks). Chunk might be a `string`, `Uint8Array` or `Buffer` (Node.js only):
+```js
+const { parseChunked } = require('@discoveryjs/json-ext');
+const encoder = new TextEncoder();
+
+// generator
+parseChunked(function*() {
+    yield '{ "hello":';
+    yield Buffer.from(' "wor');    // Node.js only
+    yield encoder.encode('ld" }'); // returns Uint8Array(5) [ 108, 100, 34, 32, 125 ]
+});
+
+// async generator
+parseChunked(async function*() {
+    for await (const chunk of someAsyncSource) {
+        yield chunk;
+    }
+});
+
+// function that returns iterable
+parseChunked(() => ['{ "hello":', ' "world"}'])
+```
+
+Using with [fetch()](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API):
+
+```js
+async function loadData(url) {
+    const response = await fetch(url);
+    const reader = response.body.getReader();
+
+    return parseChunked(async function*() {
+        while (true) {
+            const { done, value } = await reader.read();
+
+            if (done) {
+                break;
+            }
+
+            yield value;
+        }
+    });
+}
+
+loadData('https://example.com/data.json')
+    .then(data => {
+        /* data is parsed JSON */
+    })
+```
+
+### stringifyStream(value[, replacer[, space]])
+
+Works the same as [`JSON.stringify()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify), but returns an instance of [`ReadableStream`](https://nodejs.org/dist/latest-v14.x/docs/api/stream.html#stream_readable_streams) instead of string.
+
+> NOTE: WHATWG Streams aren't supported yet, so function available for Node.js only for now
+
+Departs from JSON.stringify():
+- Outputs `null` when `JSON.stringify()` returns `undefined` (since streams may not emit `undefined`)
+- A promise is resolving and the resulting value is stringifying as a regular one
+- A stream in non-object mode is piping to output as is
+- A stream in object mode is piping to output as an array of objects
+
+When to use:
+- Huge JSON needs to be generated (e.g. >500MB on Node.js)
+- Needed to reduce memory pressure. `JSON.stringify()` needs to generate the entire JSON before send or write it to somewhere. With `stringifyStream()` you may send a result to somewhere as first bytes of the result appears. This approach helps to avoid storing a huge string in the memory at a single time point.
+- The object being serialized contains Promises or Streams (see Usage for examples)
+
+[Benchmark](https://github.com/discoveryjs/json-ext/tree/master/benchmarks#stream-stringifying)
+
+Usage:
+
+```js
+const { stringifyStream } = require('@discoveryjs/json-ext');
+
+// handle events
+stringifyStream(data)
+    .on('data', chunk => console.log(chunk))
+    .on('error', error => consold.error(error))
+    .on('finish', () => console.log('DONE!'));
+
+// pipe into a stream
+stringifyStream(data)
+    .pipe(writableStream);
+```
+
+Using Promise or ReadableStream in serializing object:
+
+```js
+const fs = require('fs');
+const { stringifyStream } = require('@discoveryjs/json-ext');
+
+// output will be
+// {"name":"example","willSerializeResolvedValue":42,"fromFile":[1, 2, 3],"at":{"any":{"level":"promise!"}}}
+stringifyStream({
+    name: 'example',
+    willSerializeResolvedValue: Promise.resolve(42),
+    fromFile: fs.createReadStream('path/to/file.json'), // support file content is "[1, 2, 3]", it'll be inserted as it
+    at: {
+        any: {
+            level: new Promise(resolve => setTimeout(() => resolve('promise!'), 100))
+        }
+    }
+})
+
+// in case several async requests are used in object, it's prefered
+// to put fastest requests first, because in this case
+stringifyStream({
+    foo: fetch('http://example.com/request_takes_2s').then(req => req.json()),
+    bar: fetch('http://example.com/request_takes_5s').then(req => req.json())
+});
+```
+
+Using with [`WritableStream`](https://nodejs.org/dist/latest-v14.x/docs/api/stream.html#stream_writable_streams) (Node.js only):
+
+```js
+const fs = require('fs');
+const { stringifyStream } = require('@discoveryjs/json-ext');
+
+// pipe into a console
+stringifyStream(data)
+    .pipe(process.stdout);
+
+// pipe into a file
+stringifyStream(data)
+    .pipe(fs.createWriteStream('path/to/file.json'));
+
+// wrapping into a Promise
+new Promise((resolve, reject) => {
+    stringifyStream(data)
+        .on('error', reject)
+        .pipe(stream)
+        .on('error', reject)
+        .on('finish', resolve);
+});
+```
+
+### stringifyInfo(value[, replacer[, space[, options]]])
+
+`value`, `replacer` and `space` arguments are the same as for `JSON.stringify()`.
+
+Result is an object:
+
+```js
+{
+    minLength: Number,  // minimal bytes when values is stringified
+    circular: [...],    // list of circular references
+    duplicate: [...],   // list of objects that occur more than once
+    async: [...]        // list of async values, i.e. promises and streams
+}
+```
+
+Example:
+
+```js
+const { stringifyInfo } = require('@discoveryjs/json-ext');
+
+console.log(
+    stringifyInfo({ test: true }).minLength
+);
+// > 13
+// that equals '{"test":true}'.length
+```
+
+#### Options
+
+##### async
+
+Type: `Boolean`  
+Default: `false`
+
+Collect async values (promises and streams) or not.
+
+##### continueOnCircular
+
+Type: `Boolean`  
+Default: `false`
+
+Stop collecting info for a value or not whenever circular reference is found. Setting option to `true` allows to find all circular references.

+# Parser function for floating point hexadecimals
+
+[![license](https://img.shields.io/github/license/maurobringolf/@webassemblyjs/floating-point-hex-parser.svg)]()
+[![GitHub last commit](https://img.shields.io/github/last-commit/maurobringolf/@webassemblyjs/floating-point-hex-parser.svg)]()
+[![npm](https://img.shields.io/npm/v/@webassemblyjs/floating-point-hex-parser.svg)]()
+
+> A JavaScript function to parse floating point hexadecimals as defined by the [WebAssembly specification](https://webassembly.github.io/spec/core/text/values.html#text-hexfloat).
+
+## Usage
+
+```javascript
+import parseHexFloat from '@webassemblyjs/floating-point-hex-parser'
+
+parseHexFloat('0x1p-1')               // 0.5
+parseHexFloat('0x1.921fb54442d18p+2') // 6.283185307179586
+```
+
+## Tests
+
+This module is tested in two ways. The first one is through a small set of test cases that can be found in [test/regular.test.js](https://github.com/maurobringolf/@webassemblyjs/floating-point-hex-parser/blob/master/test/regular.test.js). The second one is non-deterministic (sometimes called *fuzzing*):
+
+1. Generate a random IEEE754 double precision value `x`.
+1. Compute its representation `y` in floating point hexadecimal format using the C standard library function `printf` since C supports this format.
+1. Give both values to JS testcase and see if `parseHexFloat(y) === x`.
+
+By default one `npm test` run tests 100 random samples. If you want to do more, you can set the environment variable `FUZZ_AMOUNT` to whatever number of runs you'd like. Because it uses one child process for each sample, it is really slow though. For more details about the randomized tests see [the source](https://github.com/maurobringolf/@webassemblyjs/floating-point-hex-parser/tree/master/test/fuzzing).
