## README

# json-stringify-pretty-compact

The output of [JSON.stringify] comes in two flavors: _compact_ and _pretty._ The former is usually too compact to be read by humans, while the latter sometimes is too spacious. This module trades performance for a compromise between the two. The result is a _pretty_ compact string, where “pretty” means both “kind of” and “nice”.

<!-- prettier-ignore -->
```json
{
  "bool": true,
  "short array": [1, 2, 3],
  "long array": [
    {"x": 1, "y": 2},
    {"x": 2, "y": 1},
    {"x": 1, "y": 1},
    {"x": 2, "y": 2}
  ]
}
```

While the “pretty” mode of [JSON.stringify] puts every item of arrays and objects on its own line, this module puts the whole array or object on a single line, unless the line becomes too long (the default maximum is 80 characters). Making arrays and objects multi-line is the only attempt made to enforce the maximum line length; if that doesn’t help then so be it.

## Installation

```
npm install json-stringify-pretty-compact
```

```js
import stringify from "json-stringify-pretty-compact";
```

> **Note:** This is an [ESM only package]. (I haven’t written that gist, but it’s a great resource.)
>
> If you need CommonJS, install version 3.0.0. You won’t be missing out on anything: This package is _done._ No more features will be added, and no bugs have been found in years.

## `stringify(obj, options = {})`

It’s like `JSON.stringify(obj, options.replacer, options.indent)`, except that objects and arrays are on one line if they fit (according to `options.maxLength`).

`options`:

- indent: Defaults to 2. Works exactly like the third parameter of [JSON.stringify].
- maxLength: Defaults to 80. Lines will be tried to be kept at maximum this many characters long.
- replacer: Defaults to undefined. Works exactly like the second parameter of [JSON.stringify].

`stringify(obj, {maxLength: 0, indent: indent})` gives the exact same result as `JSON.stringify(obj, null, indent)`. (However, if you use a `replacer`, integer keys might be moved first.)

`stringify(obj, {maxLength: Infinity})` gives the exact same result as `JSON.stringify(obj)`, except that there are spaces after colons and commas.
