typeson | Preserves types over JSON , BSON or socket.io | JSON Processing library

I'm developing a Web application to send images, videos, etc. to two monitors from an admin interface. I'm using ws in Node.js for the server side. I've implemented selecting images available on the server and external URLs and sending them to the clients, but I also wanted to be able to directly send images selected from the device with a file input. I managed to do it using base64 but I think it's pretty inefficient.

Currently I send a stringified JSON object containing the client to which the resource has to be sent, the kind of resource and the resource itself, parse it in the server and send it to the appropriate client. I know I can set the Websocket binaryType to blob and just send the File object, but then I'd have no way to tell the server which client it has to send it to. I tried using typeson and BSON to accomplish this, but it didn't work.

Are there any other ways to do it?

I need to create a LDAP client that works on linux using .NET Core. I searched trought the internet and the only library that support .Net Standard is Novell.Directory.Ldap (open source, iei - https://github.com/dsbenghe/Novell.Directory.Ldap.NETStandard). Directory Service library does not have support in .Net Core for Linux, only on Windows.

I looked to the documentation and succeded to create a basic Ldap client application.

Now the problem: I need to synchronize a lot of users (10.000, 200.000 users) and by default my ldap server has a maximum size page 1000 (and I don't want to change it). I used a VirtualListControl in order to create pages and it works ok for 10k users.

For 200k user it crashes with error 53 - unwilling to perform on the LdapSortControl response. The Novell library need a LdapSortControl in order to perform paging operation (for index) and I think that my ldap is not able to sort 200k. The code that I used:

I have take the below example from Template with Multiple pack as input parameter.

I use asn1c to parse the LDAP messages.

For this purpose, after compiling the ASN.1 Definition defined in rfc4511, I use the ber_decode and xer_fprint functions for decoding and printing content in my program.

For example, the two outputs indicated below are related to two different LDAP messages:

I am using an extended HttpClass so that I can apply headers and url paths dynamically. This is what it looks like:

app.http.ts

I need to extract a string after opResult and before another string (word+ '=')

For example:

testest=false opResult=Critical extension not supported random=abc srcPort=10

So I should extract out Critical extension not supported, before the next word with an equals sign.

Also, it should also work if there is no other string at the back, meaning I should get the same result with the below example.

typesOnly=false opResult=Critical extension not supported

The regular expression I have currently extracted everything before the last '=' sign.
