multiparser on Deno 1.2 about multiparser HOT 6 CLOSED

this is the problem described in #4 .

from multiparser.

v2.0.1 is out. Please check it out.

https://github.com/deligenius/multiparser/releases/tag/v2.0.1

from multiparser.

Tried a simple example.

export const createPost2 = async (ctx: any) => {
try{
const form = await multiParserV2(ctx.request.serverRequest);
//console.log(JSON.stringify(form,null,2));
console.log(title ${form?.fields.title});
console.log(content ${form?.fields.content});
console.log(creator ${form?.fields.creator});
console.log(imageUrl ${form?.files.imageUrl.filename});
ctx.response.status = 201;
ctx.response.body = { message: 'Post created succesfully', post: {}, creator: {_id: '233', name: ''},imageUrl:form?.files.imageUrl };
}catch(err){
console.log(err);
}
};

But gave this output.

If I comment this line
console.log(imageUrl ${form?.files.imageUrl.filename});

it works. But if i enable it , it gives this error.

error: TS2339 [ERROR]: Property 'filename' does not exist on type 'FormFile | FormFile[]'.
Property 'filename' does not exist on type 'FormFile[]'.
console.log(imageUrl ${form?.files.imageUrl.filename});

I know the filename exists, because i can see it on the return from the api.

A field may contain many files, before use that, you need to cast type

(<FormFileV2>form?.files).imageUrl

from multiparser.

It works!

Here is the working example

export const createPost2 = async (ctx: any) => {
try{
const form: FormV2 = await multiParserV2(ctx.request.serverRequest) as FormV2 ;
//console.log(JSON.stringify(form,null,2));
console.log(title ${form?.fields.title});
console.log(content ${form?.fields.content});
console.log(creator ${form?.fields.creator});
console.log(imageUrl ${(<FormFileV2>form?.files.imageUrl).filename});
await Deno.writeFile(./images/test.png, (form?.files.imageUrl).content);
ctx.response.status = 201;
ctx.response.body = { message: 'Post created succesfully', post: {}, creator: {_id: '233', name: ''},imageUrl:form?.files.imageUrl };
}catch(err){
console.log(err);
}
};

I'm glad it works for you
