Usage

basic

const { TextStream } = require('lite-sse-chunk');
const stream = new TextStream();
stream.addChunkListener((messages) => {
    console.log(messages); // the messages of newest chunk
    console.log(Array.isArray(messages)); // always true!
});

theSource.on('chunk', (chunk) => {
    const text = decodeText(chunk); // decode the chunk to text if the chunk is binary
    stream.receive(chunk);
});

custom chunk read

const { TextStream, createRegexExtractor } = require('lite-sse-chunk');
const reader = createParser(/xxxx: (.*)\n\n/g);
const stream = new TextStream(reader);
stream.addChunkListener((messages) => {
    console.log(messages); // the messages of newest chunk
    console.log(Array.isArray(messages)); // always true!
});

theSource.on('chunk', (chunk) => {
    const text = decodeText(chunk); // decode the chunk to text if the chunk is binary
    stream.receive(text);
});

the result:

< chunk1 start
xxxx: hello

xxxx: world!

< chunk1 end

==> messages : ['hello', 'world!']
