QUESTION
I need to find the sizes/metadata of externally hosted images in a document (e.g., markdown documents that have image tags in it), but need to do it without actually downloading the image.
Is there any way to do this easily on NodeJS/ExpressJs using javascript? Some of the solutions are many years old and not sure if there are better methods now.
...ANSWER
Answered 2021-Jun-15 at 01:47You can do what was suggested in comments by only grabbing the HEAD
instead of using a GET
when you call the image.
Using got or whatever you like (http, axios, etc) you set the method
to HEAD
and look for content-length
.
My example program that grabs a twitter favicon, headers only, looks like this:

We are overriding console.log
in our productive ExpressJS application to add certain fields (e.g. timestamp, sessionid, requestid) as well as send logs to a syslog server.
We are doing this by adding console.requestId
and console.sessionId
properties to the global console
object and then overriding console.log()
to output these values as well as send logs to syslog. This works fine:

I'm trying to create chat with nestjs, and it is problem with its @SubscribeMessage()
,
implementation with connection is working, but when I try to listen the emits from frontend and console
the data in nestjs, it not works
ANSWER
Answered 2021-Apr-29 at 15:42Based on NestJS Websocket documentation, the NestJS socketIO server is still in v2.
@nestjs/platform-socket.io currently depends on socket.io v2.3 and socket.io v3.0 client and server are not backward compatible. However, you can still implement a custom adapter to use socket.io v3.0. Please refer to this issue for further information.
If you check the version compatibility, you will see that socketIO server v2 is not compatible with socketIO client v4.
The easiest solution would be to use socket.io-client
v2.3.0
in your package.json
of frontend.
Or, if you like to explore: socketIO server v3 is compatible with socketIO client v4. So I believe you can take a look into this issue (as mentioned in NestJS docs) and try to convert your NestJS socketIO server to support socketIO client v3. Hopefully, that would also support socketIO client v4 as well. (I didn't test this though!)
Hope this helps you. Cheers 🍻 !!!
QUESTION
Let's say I a web server with most of the endpoints publicly accessible. I want some of them to be accessible just by me (though it could be a group of people eventually).
I'm looking for the most bare-bone solution. I would not want to implement users accounts for example.
The webserver is implemented with express and nodejs. I run the server with nginx in case that helps, but if possible implemeting this at app level would be better.
