json_seq
A Deno module for working with streams of individual JSON objects, using the json-seq format described in RFC 7464.
Usage
// examples/print_stream_contents.ts
import { JsonSequenceDecoderStream } from "https://deno.land/x/json_seq@v0.1.0/mod.ts";
import { readableStreamFromReader } from "https://deno.land/std@0.117.0/streams/conversion.ts";
const jsonStream = readableStreamFromReader(Deno.stdin)
.pipeThrough(new JsonSequenceDecoderStream());
for await (const json of jsonStream) {
console.log(`JSON value: ${Deno.inspect(json)}`);
}$ echo -e '\x1E{"message": "hi"}\n\x1E{"message": "bye"}\n' \
| deno run examples/print_stream_contents.ts
JSON value: { message: "hi" }
JSON value: { message: "bye" }Roadmap
- Implement stream encoding
- Review the non-strict decoding behaviour and more closely follow the lenient
handling of malformed streams described in the RFC
- Maybe allow visibility of/control over malformed stream recovery actions
