read(input, [options]) ⇒ AsyncIterator

Accepts a ReadableStream, an AsyncIterator, an array or a string and returns an AsyncIterator.

Kind: global function
Returns: AsyncIterator - Returns an AsyncIterator which yields Promises which resolve to parsed data.

| Param | Type | Description | | --- | --- | --- | | input | ReadableStream | AsyncIterator | Array | string | Raw input data | | [options] | Object | Optional options object. |

Example

for await (const result of read('{ "StartAt": "a", "States": { "a": { "Type": "Pass", "Next": "b" }, "b": { "Type": "Pass", "End": true } } }')) {
    console.log(result);
}
// => digraph { a -> b }

readToStream(input, [options]) ⇒ WritableStream

Accepts a ReadableStream, an array or a string and returns a WritableStream. Stream output will be utf-8 text. Stream values will be delimited by a system-native newline escape character.

Kind: global function
Returns: WritableStream - Returns a WritableStream Stream output will be utf-8 text. Stream values will be delimited by a system-native newline escape character.

| Param | Type | Description | | --- | --- | --- | | input | ReadableStream | AsyncIterator | Array | string | Raw input data | | [options] | Object | Optional options object. |

Example

readToStream('{ "StartAt": "a", "States": { "a": { "Type": "Pass", "Next": "b" }, "b": { "Type": "Pass", "End": true } } }').pipe(process.stdout);
// => digraph { a -> b }

readOne(input, [options]) ⇒ Promise

Accepts a ReadableStream, an AsyncIterator, an array or a string and returns a Promise which resolves to the first value of the stream.

Kind: global function
Returns: Promise - Returns a Promise which resolves to the first value of the stream.

| Param | Type | Description | | --- | --- | --- | | input | ReadableStream | AsyncIterator | Array | string | Raw input data | | [options] | Object | Optional options object. |

Example

console.log(await readOne('{ "StartAt": "a", "States": { "a": { "Type": "Pass", "Next": "b" }, "b": { "Type": "Pass", "End": true } } }'));
// => digraph { a -> b }

readAll(input, [options]) ⇒ Promise

Accepts a ReadableStream, an AsyncIterator, an array or a string and returns a Promise which resolves to an array of all values.

Note: If a stream or iterator is passed to readAll and it does not complete, the Promise returned by this function will never resolve.

Kind: global function
Returns: Promise - Returns a Promise which resolves to an array of all values.

| Param | Type | Description | | --- | --- | --- | | input | ReadableStream | AsyncIterator | Array | string | Raw input data | | [options] | Object | Optional options object. |

Example

console.log(await readAll('{ "StartAt": "a", "States": { "a": { "Type": "Pass", "Next": "b" }, "b": { "Type": "Pass", "End": true } } }'));
// => digraph { a -> b }
