Construct JSON without backing it up with Go structures

This repository is archived. See https://github.com/dottedmag/tj for the current version.

Use tj to produce well-formed schemaless JSON:

json.Marshal(tj.O{
    "hello": tj.A{
        "world",
        42,
        tj.O{
            "go": nil,
        },
    },
})

tj/json2go tool produces tj trees from existing JSON or YAML files.

Why whould I need that?

This package comes in handy for interacting with large amounts of external systems all demanding different JSON schemas. Creating structures, tagging them and filling them is overkill if the structures are used just once.

Why do I need this package to do so?

tj.O and tj.A are short and unobtrusive, this makes the resulting code readable.

Is it always a good idea to use this package?

If you find yourself using tj to describe JSONs with the same schema more than once then it's time to switch to Go struct-backed JSON generation.
