Why is there not a @types/gatsby package?

[alexluong]

Hi,

I'm trying out TypeScript with Gatsby for the first time and quite surprised that there is no @types/gatsby package. I think it would be helpful, especially if someone want to implement the Node/Browser/SSR in TypeScript.

Some example code:

export function sourceNodes({ actions, createNodeId }: SourceNodesParam) {}

Types are available, and are distributed alongside the library.

https://unpkg.com/gatsby@2.8.2/index.d.ts

Hope this helps -- thanks!

Thanks for the response. This is exactly what I'm looking for.

@DSchau Sorry for bothering, but using types from Gatsby create a false error for me:

    createNode({
      ...obj,
      id: createNodeId(`Obj-${post.id}`),
      parent: "",
      children: [],
      internal: {
        type: "Obj",
        content: nodeContent,
        contentDigest: crypto
          .createHash("md5")
          .update(nodeContent)
          .digest("hex"),
      },
    })

It complains:

Type '{ type: string; content: string; contentDigest: string; }' is missing the following properties from type '{ type: string; mediaType: string; content: string; contentDigest: string; owner: string; description?: string | undefined; }': mediaType, owner

What I think is happening is here:

export interface Actions {
  ...

  createNode(node: Node, plugin?: ActionPlugin, options?: ActionOptions): void
}

It expects a Node as an argument where mediaType is not optional and owner field exists within internal.

Maybe there should be a NodeInput where mediaType is optional and there is no owner field?

@alexluong we'd love a PR making those types a little more flexible!

@DSchau Created a PR with a follow-up question. We can discuss over there! Thanks for the support.
