appendable-json

Appendable JSON based format

file format

By storing the following variable:

const example = [
    123,
    "Lorem,\nipsum."
];

I started with a JSON array.

[123,"Lorem,\nipsum."]

Our main problem with the JSON format, that the square brackets make it hard to append without parsing. So I removed the square brackets.

123,"Lorem,\nipsum."

This is not bad, we could append it by adding ,"next", but I don't like that the first item is different, so I added comma at the end.

123,"Lorem,\nipsum.",

Now if we want to parse only the second item, then we have a problem to find it without parsing the whole string, because the lorem ipsum string contains a comma. I added a line break after the separator comma to solve this. Since the compact JSON coming from JSON.stringify does not contain any line break, this should suffice.

123,
"Lorem,\nipsum.",

I like this format, because it is easy to parse and build and it is great for logging or for file based event storages.
