Since Qwik is React-like and not a React runtime, not all of the popular libraries that exist in the React ecosystem exist in the Qwik ecosystem. Is there an existing Qwik alternative to Formik?
You can follow Qwik-react project to know how to use React components in Qwik.

I don't think at the moment we have any thing alternative for Formik in Qwik

I am having a login and signup form in my app for which I need to do input fields validation.
I am beginner to React-Native app development.
I have tried some packages:
reference:
https://github.com/NewOldMax/react-native-validator-form
https://github.com/n4kz/react-native-material-textfield
essential package versions I am using for my app:
"react": "16.9.0",
"react-native": "0.61.5",
but I am having little difficulties in working with them. So I need to handle validations from my app side in react-native only. Any help would be really appreciated.
create your own validation checking
onChangeText or onSubmit check the error through validators. here is helper funtions that I have use in my application.
you can use RegEx patterns/rules to validate TextInputs
there is a medium article https://medium.com/#react.ui.kit/react-native-textinput-validation-using-regex-patterns-rules-d811e8eee9aa
The formik documentation seems to discourage use of the useFormik hook - but the entire Getting Started tutorial exclusively uses useFormik - so I'm not sure how to proceed - it's very confusing. Is there a downside of using useFormik if I don't need connect, FastField, ErrorMessage, etc.
I don't think it discourages you to use useFormik, but in most of the use cases it's not necessary, as you won't get any perks of using context api. Field, FieldArray, etc uses formik context internally so you won't be able to use these components. But in my opinion by using this useFormik hook you'll be creating more of your own implementation for these kind of components. But it doesn't hurt to learn that as well as internals of Formik are based on this hook.
Currently I am learning react. can anyone tell me what is the main application usage of react hooks and how can we take more advantage of using hooks with react.?
Basically, before if a component had state or needed to utilize a lifecycle method, we had to use a class, which requires a bunch of extra code.
Now that is not the case. With hooks, instead of ever having to use a class, we could just always use a function.

I'm using pouchdb as a library in a tiddlywiky project. It provides a common js compatible environment, so I can just require it.
My project is targeted to several browsers so I can't expect promises to be available as default. Since pouchdb uses promises extensively I tough that it will be simpler to use promises in the rest of my code. I know that pouch includes a promise polifil, so here is my question :
Is that polifil available from outside? Can I use it? How?
Thanks and regards
Yes, you can use PouchDB's promise polyfill by using pouchdb-promise: https://www.npmjs.com/package/pouchdb-promise
If you are using npm, then it's just require('pouchdb-promise'). Otherwise, you can get it from wzrd.in: https://wzrd.in/standalone/pouchdb-promise
What is the best approach to version WebAPIs?
I am building an API from scratch and I would like to ensure that it will version gracefully in the future. I am envisioning something like mysite.com/api/v2/...
One approach I see is to create a separate project (web app) for each version of API. But perhaps there are better ways to do it?
Thank you for your ideas.
Including version number in the URL is the standard approach as I explained in this post (I do not repeat the content): Implementing versioning a RESTful API with WCF or ASP.Net Web Api
You do not need to create a completely new project although you can. The problem that you will be facing with a single project is that there will be collision of names:
/api/v1.0/Car/123
and
/api/v2.0/Car/123
both will point to CarController while you can have only one of those. The solution would be to implement your own IHttpControllerSelector and register with the DependencyResolver. This implementation will look at the version number and perhaps find the type based on the namespace.
UPDATE
I do not intend to start a REST controversy here. But as #DarrelMiller points out, here is an older discussion on the same subject discouraging my suggested approach:
How to version REST URIs
I personally think URL versioning is the way to go.
You will need to create your own implementation of IHttpControllerSelector. The best way is to base this implementation on Microsoft's IHttpControllerSelector. Then you can decide in your IHttpControllerSelectorif you want to version by URL or by content-type.
The most basic implementation directly implements IHttpControllerSelector and just implements the SelectController method but performance reasons it is better to implement some caching around it.
For finding the Controller you simple the IHttpControllerTypeResolver instance you can get using HttpConfiguration.Services.
I've used something like this: http://damsteen.nl/blog/implementing-versioning-in-asp.net-web-api. Also put some code on Github: https://github.com/Sebazzz/SDammann.WebApi.Versioning.
