I am working on ReactJS for developing a client side of an application, there are very few options available for client side logging as compared to server side on of them which I came across is log4js it has appenders. But are there any other options available? I've used Winston on server side few months ago, can we use such libraries on client side as well? The issue here is I'll have to remove these logs completely before taking this code to production, so I guess I'll use webpack's module for it. But log4js seems to be an overhead so what all alternatives can be used?
I am facing a similar problem at our end. So far I have came across the following options which may be of help:
log Level:
Logs at different levels, easy to setup, somewhat similar to bunyanJs and WinstonJS which are used in the backend Nodejs servers.
loglevel-plugin-remote - extension of log level but pushes logs to server after specified interval. There are in fact quite a few more options there
It has been almost 4 years since I've asked this question, and now looking at the choices available in market we've decided to go ahead with application monitoring/tracking systems such as sentry for logging the event. We can build a wrapper around the SDK of such services and log the events to track the issue.
Another option was to build our own service, but considering the product in mind the maintenance cost of our own service would have been much more, so we sticked with sentry. There are many other similar options available as well for logging on frontend as well as backend.

How to integrate kafka with react native for chat and real time tracking of a client.
and is it possible to implement or i want to use socket io for it give me a solution
A quick solution would be to put the Kafka cluster behind a simple REST API. Using a library like kafka-rest could be an easy way to connect your React Native app using the built in fetch function. You could go a step further and try to integrate the kafka-rest-node client into your React Native app; a cursory overview of the repo doesn't lead to any core Node dependencies.
Another method, one which would allow for "live" updates, might consist of putting Kafka behind a web server that converts the Kafka stream into a WebSocket connection. Libraries such as kafka-websocket allow clients to both consume and produce, whereas a more simple library like Microsoft's kafka-proxy-ws only allows for consuming messages.
It's worth noting that mobile clients don't always work well with streaming data, and you'd be advised to test your WebSocket-based implementation on a variety of uncertain network conditions (latency, dropped signals, etc).

I'm looking for a solution (probably CMS or framework) to make a database and user friendly interface for data entry by regular users.
At our department we're doing a lot of data collection - 6 DBs, 2k records, ~100-200 fields. All of them are powered by in-house Rails application that's hard to maintain on this scale. So, I'm looking for a more tailored solution.
What is important:
Well-thought database design and data management solution (migrations, validation, etc)
Almost unlimited customisation (backend and frontend programming), especially an ability to make complex inputs
Great community to learn and contribute (open source)
What will be nice to have:
Python/Ruby/etc backend. Modern React (at least not Angular) frontend
PostgreSQL support
Plugins, integration with other services
Something I've found: Oracle APEX, MS Access, FileMaker (proprietary), nuBuilder (very limited). After all, I thought about rewriting our app using PostgREST and React or use Plone as a basis (but a bit afraid of ZODB). What do you think?
Any help and advices are appreciated, thx.
PostgreSQL + PostgREST + react-admin
Reactrb plus rails. Very simple to use 100% ruby see http://reactrb.org

I am developing an dashboard application which will give insights of the data of an organisation. I am confused as to what will be the best approach in developing the Dashboard:
a. Should i go for Crystal Reports
b. Should i Use WPF Charts and display Data
Any suggestions please which help me go ahead with my design?
Regards
Vineet More
It depends on your goals.
Using WPF and charting controls will likely be simpler to deploy since it's a client application (you won't have to worry about Crystal being setup correctly). They come with the framework and won't have any additional upfront costs and it should run seamlessly across workstations.
Crystal is nice though especially if you want to send the output to the printer as a report (this is where it's roots are and it excels at it). It's a pain to deploy locally and even more of a pain to deploy on the server (where it uses the C:\Windows\Temp directory during the report export process which you probably won't have access or permissions to on a server in the cloud... or have access to the registry to change that location).
Another option you can consider is using HTML and JavaScript with a 3rd party charting library like d3. You an render the content from your client app in a web browser control and make it look seamless with your app. This approach would also make it easier to move it to the web if you ever wanted to render it from a ASP.NET site (or really from any web language).

A project I'm working on currently involves using a disparate set of technologies, including .NET, PHP, Asterisk and bash scripting. Each of the applications in use produces some logging; technical logging for administrators and user logging. The technical logging is easy, all logs are written to disk as text files.
For the user logging, I'd like a central portal where messages can be viewed, filtered and perhaps reported on.
Essentially, I'm looking for a web based application that will accept a number of log sources (including web services and syslog at a minimum), allow the logs to be stored, displayed and filtered in a web UI and ideally have the possibility of triggering events such as email or SMS.
I'm about to embark on writing this application; before I do, I want to make sure that I'm not reinventing the wheel. Any pointers/recommendation?
EDIT
I've found Exceptioneer and Hoptoad - both of which look promising - are there any other tools like this (ideally open source) ?
I think Loggly seems to most closely meet my requirements. I also found Errbit (open source HopToad-alike), LogStash (looks a bit immature for now) and GrayLog2.
I suspect I'll give Loggly and Hoptoad a go.
Logverse might be in the ballpark of what you are looking for.

Before going into production, our client demands actual numbers of how many users our web application can handle.
We have all kinds of features implemented including asset management (file uploads/downloads), documents import/export, various statistics, web-services etc.
I guess we need tool which could emulate users form submission because documents import/export as far as I noticed is the slowest part of an app because of parsing and generation.
Which tool (or set of tools) could do this?
Application details:
XHTML/jQuery
Coldfusion 8
SQL Server 2008
Windows Server 2008
I like jMeter - free software and does the job quite well.
Few intro screencasts:

http://vimeo.com/10164982
HPs Open Source HTTPerf I like. Just setup the URLS you want to test and let it rip. use a couple of machines to emulate load. You could even parse the output into a DB and do some number crunching.
Also, think about doing HTTPerf runs with profiling on the server side to see what lags and what doesnt. A nice touch is to let a user go on the app, and record all POST/GET requests and use them as a replay set for typical user interactions.
Also, if you are thinking about UX, use firebug or something to check JS imports are being done asynchronously instead of one-at-a-time. Have a ganders at Stackoverflow question 310583/loading-javascript-dependencies-on-demand

it's very good
There are few analytical performance tool out in market(not free) one i came through and works well is New Relic. If you are looking only to test the api then http://locust.io/ is good one and free too.
