Ipfs package

Changes

HTTP plugin

I have refactored the HTTP plugin to support sending body as form data (this is necessary as IPFS expects files to come in this way). Currently, I implemented this by defining Body type to be:

type Body {
  stringBody: String
  rawBody: Bytes
  formDataBody: FormData!
}

This allows users to define what kind of request body (payload) is going to be sent. I am not entirely pleased with this solution...it would be for sure better to define a union type for the body that would include all defined types (body: String | Bytes | FormData) but we are not going to support this so I had to find a workaround. Another idea is to have multiple post functions defined within HTTP plugin (postWithStringPayload, postWithFormDataPayload,...).

@dOrgJelli I would like to hear what you think about the current solution.

IPFS package

Implemented catFile, catToString and addFile ipfs functions + e2e tests.

Other

I expanded query command of CLI to support defining paths toward files in format file:path/to/file/example.txt. This will read file content and convert it to Uint8Array. This is used when testing ipfs function addFile, but I think functionality itself could be useful in multiple usecases.

TODO

I can't figure out why, but when inside schema definition of HTTP plugin I set property formDataBody of body to be nullable then generated code has a problem on the compilation. For some reason in generated function writeHttp_Body even though there is a check if (type.formDataBody) before calling write, the type is being considered to be Http_FormData | null, and because of that compilation fails.

Here is the error message:

Compile Web3APIERROR TS2322: Type 'src/mutation/w3/imported/Http_FormData/index/Http_FormData | null' is not assignable to type 'src/mutation/w3/imported/Http_FormData/index/Http_FormData'.

     Types.Http_FormData.write(writer, type.formDataBody);
                                       ~~~~~~~~~~~~~~~~~
 in src/mutation/w3/imported/Http_Body/serialization.ts(29,39)

And here is a snip from generated code where an error occurs:

export function writeHttp_Body(writer: Write, type: Http_Body): void {
  writer.writeMapLength(3);
  writer.writeString("stringBody");
  writer.writeNullableString(type.stringBody);
  writer.writeString("rawBody");
  writer.writeNullableBytes(type.rawBody);
  writer.writeString("formDataBody");
  if (type.formDataBody) {
    Types.Http_FormData.write(writer, type.formDataBody);
  } else {
    writer.writeNil();
  }
}

hey @MakMuftic I am trying to build this locally but I am getting an error:

Probably I am missing something, do you have any idea?
