Can someone help me with koa-jwt. I have it configured but for some reason it is still throwing a 401 even after I am signed in.

Anyone know how i can modify a specific visitor sessions outside the scope of koa (ctx) ? Getting certain info from Jayson TCP sockets that i want to apply to the correct users session.

Does Koa support keep-alive by default? If not, how can one enable it?

Here is a new project. https://github.com/goa-go/goa just like koa for golang, I'm looking for someone to join us.

Hi
Wow no chat since 1 month...
Can I add an extra arguments to session.save with koa-session?
I want to add some data to the stored session in the same insert

Hi guys, a question for you:

tl;dr: Trying to create a mock context like this:

const ctx = createContext({
      method,
      headers,
      body,
    });

throws TypeErrors

https://stackoverflow.com/questions/57864117/koa-create-context-cannot-set-headers-or-body

delphi
@johndeguerto
@vamsiampolu I think headers, methods don’t have setting when an hTTP method is get other than post. So context are executed once upon start of the server. perhaps the app.use( ) where you intialize context to run should be higher in the code chain prior to other middleware?

Hello everyone. I want to use Koa for my next project. What is actual real world advantage of koa over express?. I want it for my api backend.

AuthorizationMiddleware is still calling on first routes why?
delphi
@johndeguerto
@vimalmistry are you having an issue or are you asking why auth is being called in your load routes?
Vimal Mistry
@vimalmistry
@johndeguerto Thanks for reply. I have solved this issue by calling authRoute.use(myMiddleware) :)

Hi, what is best npm for koa/health

Hi, having a problem with setting ctx.body = a stream (sort of). Im using csv-stringify npm module's streams support, so my code is generally doing something like this: ctx.body = stream; await someCodeThatGeneratesCsvRows(stream); stream.end();
I should first say that the code works. The thing that's confusing me is that no rows come to the browser until all rows are generated (e.g. until stream.end() is called). I changed my stream writer to be something a bit more complex, like this, which vaguely what they say to do anyway in the Writable stream docs, const writer = (stream) => (obj) => { return new Promise((resolve) => { if (!stream.write(obj)) { stream.once('drain', resolve); } else { process.nextTick(resolve); } }); };
and when I do that, stream.write does indeed return false at some point but the drain event never arrives, so my request just hangs.
my vague guess is that Im doing something wrong and Koa isn't reading from the stream until .end() but I could be mistaken on that
Kevin
@kevinludwig
ok well I figure out how to get it working...after reading some koa source code. I need to not await someCodeThatGeneratesCsvRows(stream) and instead do ctx.body = stream; someCodeThatReturnsAPromiseThatIWontAwait(stream).then(() => stream.end());
...because Koa doesn't attach the pipe to the stream until after my middleware returns. Is this the way I'm supposed to be doing this? I don't think there's any examples that make this particularly clear in the docs...
If its not clear why I might be doing this, Imagine I'm reading blocks of data from a db (or another api) to fetch parts of a dataset, and then tranforming that data into CSV, and writing the CSV rows to a stream. So the method that generates the dataset is async, but I want koa to stream the results (obviously) as they arrive. And so given that Koa is built on top of async await it seemed natural to me that I could assign the stream and then pump data into the stream via awaiting as necessary...

if I append a middleware in the runtime of another middleware (IE. during a request), will it be considered and possibly invoked for said request?

Is there a way to load part of a session or lazy load part of it? And is there a way to store only part of the session and the all big session when only a small part of it changed?

Hi everyone, I'm a newbie to the koa framework. I need some assistance with an issue. I need to access the incoming request headers before request authentication is done. I need to insert additional headers to be used in subsequent functions/processes. Any help would be greatly appreciated. Thanks Rajiv

Shashank Agarwal
@shashank1010
Hi, a NodeJS noob here,

I intend to create an application and reuse some app logic by forwarding an API call from one route to another.

for example. A request is made for /subscribed-users and i want to add to this context and call the /users route internally.

How can i achieve this with KOA?
Any help would be welcome.

Thanks.

Mayursinh Sarvaiya
@Marvin9
@shashank1010 , ctx.redirect should be used for this purpose. Read the documentation here https://github.com/koajs/koa/blob/master/docs/api/response.md#responseredirecturl-alt.

Hi! What does the name koa mean?

@daniel-j
I'm guessing it comes from Co-routines

Sorry, forgot :P
function Property {
  this.something = 'Something'
}

Property.prototype.test = require( './test.js' )

module.exports = Property
That there, the test file will have access to the context right?
As in, this.something will exist in Property.test
But, if I want to do multiple levels, I want to add more files inside the test file so I get Property.test.a and still persist the this context
Jeff Hansen
@jeffijoe
If invoked with the right context, it should, yeah.
Ghost
@ghost~5ac084b8d73408ce4f93eee9
Is that possible?
Jeff Hansen
@jeffijoe
I would just not do that.
Ghost
@ghost~5ac084b8d73408ce4f93eee9
Why?
The idea is to split one large class file into multiple files
Jeff Hansen
@jeffijoe
I mean you can just iterate those props and bind the funcs in the ctor
What are you trying to achieve?
