QUESTION
I'm using React Hook Form v7 and I'm trying to make my data form persistent on page reload. I read the official RHF documentation which suggests to use little state machine and I tried to implement it but without success. Is there a better way to do it? However...
The first problem I encountered using it, is that my data is a complex object so the updateAction
it should be not that easy.
The second problem is that I don't know when and how to trigger the updateAction to save the data. Should I trigger it on input blur? On input change?
Here's my test code:
...ANSWER
Answered 2022-Mar-19 at 23:41The state itself won't persist any data on page reload.
You need to add your state data to Local Storage.
Then load it back into the state on componentDidMount
(useEffect with empty dependency array).
QUESTION
I am using little-state-machine
(https://github.com/bluebill1049/little-state-machine) with react-router
for a wizard on a client's site and I need to reset the store when a user returns to the wizard landing page. I followed this answer in stack overflow (React Little State Machine clear data) but I can’t get it to work. I can’t show the full application, but from the below can you see anything wrong with what I have done.
App.js
...ANSWER
Answered 2022-Feb-23 at 16:17From what I can see of the code snippet you've shared you are it appears as though this Steps
component is possibly rendering a Route
or set of Route
s corresponding to the wizard steps. If I understand your question/issue you want to reset the wizard any time the the step is 0
or some falsey value.
The issue is that Steps
only runs this check once when it mounts. To resolve you can add the location
object as a dependency to the useEffect
hook so the hook's callback is triggered any time the location
changes. The step
condition will check if on the wizard landing page and reset the state machine.
QUESTION
I built a multistep form using react-hook-form with a dynamic fields array using useFieldArray.
Documentation: useFieldArray documentation
Here is the full working code link: React Multi-step form with useFieldArray
In the 2nd step when I add new fields using add a dog button, everything works fine, the new data of step is saved to localstorage using little state machine.
But when I click the previous button, the added fields disappear whereas data is still in localstorage.
code for 2nd step:

The use is correct, the problem in my opinion is that you're not checking the state and just printing the default values everytime

QUESTION
At work, we start to do the following by lock down the package.json version
...ANSWER
Answered 2021-Feb-16 at 15:03package-lock.json
will lock it for developer installations. npm-shrinkwrap.json
will lock it for end user installations as well. So, depending on whose dependencies you're trying to pin down, you can use one or the other.
The one case I know of for doing it in package.json
is if you only want to pin some of your dependencies but not all of them.
QUESTION
This is a React style question.
TL;DR Take the set
function from React's useState
. If that function "changed" every render, what's the best way to use it in a useEffect
, with the Effect running only one time?
Explanation We have a useEffect that needs to run once (it fetches Firebase data) and then set that data in application state.
Here is a simplified example. We're using little-state-machine, and updateProfileData
is an action to update the "profile" section of our JSON state.
ANSWER
Answered 2021-Jan-12 at 23:51If you truly want the effect to run only once exactly when the component mounts then you are correct to use an empty dependency array. You can disable the eslint rule for that line to ignore it.

Answered 2020-Dec-16 at 18:31It looks like you need to create another action and pass that to the hook. You can see examples of this in the docs. Here is a working example:

So i put together this Dynamic Form Below (Hotel Rooms) and inside it you can also create dynamic forms (Room Beds). It works, i can add rooms & Beds and the object array is returned in the console.log (onSubmit).
codesandbox: https://codesandbox.io/s/charming-hermann-nzpbu?file=/src/App.js
Issue: If you add room1 and room2 and then delete room1, the array stays of length 2 and now it has "beds undefined" and it keeps growing when you add beds to other rooms! Help me solve this:
Object returned when you press next (in console). As you can see the array is not subtracting but it is also leaving the beds undefined when i delete a room:

QUESTION
I'm using react-hook-form to store form data that is split into two pages as per the code seen on Codesandbox.io. I am able to successfully store simple text inputs (like first name, email, etc) using property assignments like defaultValue={state.data.firstName}
for example...but I can't figure out how to store the checked item in the radio group using the model suggested by react-hook-form. I've checked their documentation, and it's unfortunately sparse in mentioning radio button group state storage. Is this possible using their API?
