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
AuthorizationMiddleware is still calling on first routes why?
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
...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...
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
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.
@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.
hey i wanted to share my article https://medium.com/@art_deco/how-i-compiled-koa-with-closure-63c064d7fa36 maybe someone can find it useful
function Property {
this.something = 'Something'
}
Property.prototype.test = require( './test.js' )
module.exports = Property
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
The idea is to split one large class file into multiple files
What are you trying to achieve?
My constructor() contains quite a lot of code that is used by almost every single function
So my goal is to split the entire class file into multiple files, but keep the idea of the constructor, and having the data the constructor defined, available in all the sub files
Keeping one method in one file, as they are rather long
