QUESTION
I have an application using zod but I'd like to use some methods from a different library (validator.js) zod documentation says:
Check out validator.js for a bunch of other useful string validation functions.
Not sure if that means this functions are implemented on zod, or I have to also install validator.js, in that other case how I can use both libraries together? cant find any example.
Thanks!
...ANSWER
Answered 2022-Mar-15 at 04:02I think Zod means that you could install validator.js and use their validations with Zod. Zod's refine function makes this fairly straightforward. For example if you wanted to validate a string as a credit card number using Zod and validator it might look something like this

...ANSWER
Answered 2022-Mar-07 at 12:36Looks like you are using the main branch of caliper-benchmarks. I would suggest you https://github.com/hyperledger/caliper-benchmarks/blob/main/networks/fabric/README.md
From what you have posted, you should use the latest available version of caliper which is 0.4.2, not 0.4.0. To do so the command you should issue is

QUESTION
I created a Node.js application which exports a validate function. When I use the validator in a Jest test. Jest complains the validate is not a function. the function is clearly exported and when I click on it in VS Code, it goes right to the function. Here is the validate function exported in a file called validator.js:
...ANSWER
Answered 2022-Feb-05 at 22:09The module.exports works fine. The problem was related to another import which wasn't resolved in the validator.
QUESTION
I have a task to
- Implement the functionality of sending a user's email to the server when they click on the "Subscribe" button. To do this, make a POST Ajax request using the /subscribe endpoint.
- Implement the functionality of unsubscribing the user's email from the community list when they click on the "Unsubscribe" button. To do this, make a POST Ajax request using the /unsubscribe endpoint.
- Prevent additional requests if the "Subscribe" and "Unsubscribe" buttons are pressed while requests to the /subscribe and /unsubscribe endpoints are in progress. Also, disable them (using the disabled attribute) and style them using opacity: 0.5. using React.Redux library is prohibited.
So,i have did this task,but the problem is that my form is not doing unsubscribe state,it leaves the email unchanged and the button doesnt change its state from unsubscribe to subscribe,but as a result,when an email is valid,it should give the possibility of sending subscribe fetch request to the server and the button text to change in Unsubscribe and the display of the form to be none,but if the email is not valid,then the button should have the Subscribe text,no fetch request possibilities and the input form to have the display block.Besides this,the value to be stored in local storage and when the page refreshes it leaves the form in the state it was,if was subscribed then all the changes for subscribe are actual and if not than vice-versa.
I have did this task using only javascript and it works as follows:
non-valid email:
So,the question is,what i am doing wrong? Why only subscribe fetch works and how to fix the form to make the requested result,i'm exhausted,three days i try to answer this question and i dont understand anything.. please help,thanks in advance!

QUESTION
I'm trying to validate a form via javascript onSubmit, then run the php captcha verfication and email send action. The problem is that every time I try to check the fields, I can see just one of them highlited with my CSS classes (seems to be related to the 'return false;' which blocks me).
Anyone has a clue?
Here's my HTML form code (you can see it working here: https://jsfiddle.net/xfmsLa95/2/ ):
...ANSWER
Answered 2022-Jan-22 at 21:05You returned out of the function, which is why it only works for name, and not for anything else.
Basically, what happened was it found out that usernameValue was equal to nothing and so it ran setErrorForUser(username, 'Name cannot be blank');
and returned false.
When you call return in a function it will return something and will not run anything after that.
For example,
if we had the following code -
QUESTION
I have a section on a webpage for a task :
In the form i write an email which is 'validated' later with a function.First when i submit an email which passed the validation it sends a sendSubscribe function to the server,after that i click the button unsubscribe and it sends a unsubscribeUser function.But,after that,when i click on the email input,it starts to send unsubscribe fetch requests everytime and when i click on the subscribe button it also does the same.
The network tab looks like this:
I think i know which is the problem,but i dont know how to fix it.My idea is that everytime i click on the subscribe button it ataches an event listener from the function,thats why it fires multiple unsubscribe requests.
Subscribe functions : the subscribeEmail is the most important

I'm moving my html/css/js website to Nuxt.js to get it updated automatically from an API.
I want to keep the same website so I splitted my code in components, imported my css to :

and added this in nuxt.config.js
...ANSWER
Answered 2022-Jan-10 at 15:47You can either move your scripts node (renamed script) in the head node of your nuxt.config.js file (mostly for external resources, every key/value in each script's object is an attribute) or use Nuxt's plugins as per https://nuxtjs.org/docs/configuration-glossary/configuration-plugins and https://nuxtjs.org/docs/directory-structure/plugins/.

I have a form where i enter an email and it gets ''subscribed'' in a user.json file using a fetch api on node server.My task is to :
- upon clicking on the "Unsubscribe" button, implement the functionality for unsubscribing from the community list. For that, make POST Ajax request using http://localhost:3000/unsubscribe endpoint.
I tried to make the function but it wasnt succeseful so i deleted it. Also,i need to do the following :
- While the requests to http://localhost:3000/subscribe and
http://localhost:3000/unsubscribe endpoints are in progress, prevent
additional requests upon clicking on "Subscribe" and "Unsubscribe".
Also, disable them (use the disabled attribute) and style them using
opacity: 0.5.
For me ajax requests,fetch and javascript is something new,so i dont know really well how to do this task,if you could help me i'll be happy,thanks in advance.
fetch code for subscribing:
...ANSWER
Answered 2021-Dec-20 at 02:52You should consider using a database for handling CRUD operations on your persisted data. If you must use filestorage, theres a flat file DB library called lowdb that can make working the files easier.
As for preventing duplicate requests, you can track if user has already made a request.
