Docs Data

The docsData package is responsible for creating a data structure that can be used to render docs. It does this by serializing the AST into a series of chunks, which are then sent to an external rendering process for conversion to docs pages. Docs are typically sent to the rendering process via JSONL files, but could also be sent over IPC or over a network connection.

Chunks

Core to this package is the concept of a “chunk.” A chunk is a piece of data that can be rendered into a piece of UI. Chunks are fairly similar to refs in OpenAPI, except that everything is represented as a chunk. Like refs, chunks can reference other chunks.

Some refs will correlate 1:1 with chunks, and vice versa, but this is not uniformly the case. Refs are optimized to help authors write specs more efficiently, i.e. they’re optimized for humans. Chunks however are optimized for later stages of rendering, i.e. they’re optimized for machines. As such, there are different needs of each.

Every chunk has the following base data structure:

{
  "id": "string",
  "slug": "string",
  "chunkType": "string",
  "chunkData": "object"
}
  • id - a unique id that represents this chunk. There is no semantic meaning to ids, other than that they are unique
  • slug - if non-empty, a unique URL friendly slug that represents this chunk. It may or may not be used as a URL in generated docs.
  • chunkType - a string identifying the chunk type. We use this during deserialization to know how to interpret the chunk
  • chunkData - the chunk specific data

Some examples of chunks:

  • about - a chunk that contains high-level information about the entire spec, and mostly comes from the info section of the spec
  • schema - a chunk that contains information about a schema, and is used to represent any piece of data used by operations, web hooks, etc.

Type definitions for each chunk are declared in the implementation file that processes each chunk.

func (*Docs) RegisterSlug 

func (d *Docs) RegisterSlug(id string, slug string)

TODO: This is something of a quick-n-dirty way to record and check if we've processed an chunk before, to prevent infinite recursion. It's not great though since not all chunks have slugs. We'll need to fix a few issues to make this more robust though, so I'm punting for the time being.

func (*Docs) SaveSerializedChunk 

func (d *Docs) SaveSerializedChunk(id string, serializedChunk string)

Save a serialized chunk so that we can later save it to disk. One day, we can also use this to immediately send a chunk to the renderer over IPC/etc.

	// We set null as a separate type and turn any type that is nullable into a

	// DataTypeBytes, DataTypeRequestStream, DataTypeResponseStream are all
	// combined into this binary type here
	BinaryType ValueType = "binary"
	AnyType    ValueType = "any"

	// This type is used to create a layer of indirection such that objects and
	// arrays are never nested directly. This way we can serialize circular
	// references easily, and also more give the UI more flexibility when deciding
	// how to display deeply nested data. This type is the primary difference with
	// TypeDefs, since TypeDefs have no such concept.
	ChunkType ValueType = "chunk"
)

Most of these match the types in TypeDef 1:1, but there are a few differences
