js-jsonl


Installation

``shell
npm install js-jsonl
`

Usage

`typescript
import { jsonl } from 'js-jsonl';

const jsonlString =
["Name", "Session", "Score", "Completed"]
["Gilbert", "2013", 24, true]
["Alexa", "2013", 29, true]
["May", "2012B", 14, false]
["Deloise", "2012A", 19, true]
;

const jsonlParsed = [
["Name", "Session", "Score", "Completed"],
["Gilbert", "2013", 24, true],
["Alexa", "2013", 29, true],
["May", "2012B", 14, false],
["Deloise", "2012A", 19, true]
];

expect(jsonl.parse(jsonlString)).toEqual(jsonlParsed);
expect(jsonl.stringify(jsonlParsed)).toEqual(jsonlString);

// Also works with TypeScript!

const fooBar = jsonl.parse<{ foo: 'bar' }>("{foo: 'bar'}");
const fooBarString = jsonl.stringify(fooBar)
const fooBarParsed: { foo: 'bar' } = jsonl.parse(fooBarString); // no type error!
`

You can also use the JsonlInfer helper to extract the JSONL type:

`typescript
import { jsonl } from 'js-jsonl';
import type { JsonlInfer } from 'js-jsonl';

const fooBar = jsonl.parse<{ foo: string }>("{foo: 'bar'}\n{foo: 'baz'}");
type FooBarParsed = JsonlInfer // { foo: string }
