Keep in mind that the values in meta are dependent on you having subscribed to them with the subscription prop.

you may specify only the form state that you care about for rendering your gorgeous UI. You can think of it a little like GraphQL's feature of only fetching the data your component needs to render, and nothing else.

Form validation is hard. That's why there are so many different form handling libraries for the popular web frameworks. It's usually not something that is built-it, because everyone has a different need and there is no one-fit-all solution.

Allows batch updates by silencing notifications while the fn is running. Example: form.batch(() => { form.change('firstName', 'Erik') // listeners not notified form.change('lastName', 'Rasmussen') // listeners not notified }) // NOW all listeners notified

This style of validation most closely follows WordPress’ whitelist philosophy: only allow the user to input what you’re expecting.

The equality of all sorts of human labour is expressed objectively by their products all being equally values; the measure of the expenditure of labour power by the duration of that expenditure, takes the form of the quantity of value of the products of labour; and finally the mutual relations of the producers, within which the social character of their labour affirms itself, take the form of a social relation between the products.

The beauty of using Google Sheets or another spreadsheet tool for your to do list is that you have so many formatting options. Sometimes I change the color of a cell to indicate that it's high priority. Other times I bold it. And other times I just write IMPORTANT in front of it. Whatever works. But if you like to be more consistent, you can choose colors to indicate specific things: priority, level of effort, type of tasks, or anything else you want to be able to see at a glance. For example, I always highlight a row in blue if I'm going to be out of the office. That way, I don't overschedule the week. And I highlight a row in red if it's a non-negotiable—something I have to do the day it's scheduled because of an external deadline. And because you have text formatting options—which many to do lists don't—you can make your formatting as granular as you'd like. Bold certain types of tasks, italicize others, or even add a border around cells. Whatever stands out to you visually, go with that

It's not for beginners, but it's extremely flexible once you get a handle on things. If sticking to a system is hard for you, I highly recommend giving this system a try.

There are thousands of to-do list apps out there, in part because no system works perfectly for everyone. I’m not going to say todo.txt is the exception, and that it will work for everyone, because that would be crazy. But todo.txt is the most flexible tool I’ve come across. In part, this is because of the sheer number of clients available, but also because the simplicity lends itself to improvisation.

The beauty of todo.txt is that it's completely unstructured; the fields you can attach to each task are only limited by your imagination.

this shows that it’s easy to achieve with React even without React directly supporting it.

Instead of using the empty_data option – which is only called if we create an object, but not if we update it – we will implement a custom data mapper. Symfony's data mappers are responsible for mapping the data of a form to its fields and back. For our MoneyType, Symfony's default data mapper will call the following methods when we display a form with an existing Money instance: $form->get('amount')->setData($money->getAmount()); $form->get('currency')->setData($money->getCurrency()); The properties of the Money are copied to the form simply by calling the appropriate getters. When we submit the form, the data mapper inverts that behavior: $money->setAmount($form->get('amount')->getData()); $money->setCurrency($form->get('currency')->getData()); That's where the data mapper fails. The setters setAmount() and setCurrency() don't exist. To create a custom data mapper we need to implement DataMapperInterface. Let's look at this interface: namespace Symfony\Component\Form; interface DataMapperInterface { /** * Maps properties of some data to a list of forms. * * @param mixed $data Structured data. * @param FormInterface[] $forms A list of {@link FormInterface} instances. */ public function mapDataToForms($data, $forms); /** * Maps the data of a list of forms into the properties of some data. * * @param FormInterface[] $forms A list of {@link FormInterface} instances. * @param mixed $data Structured data. */ public function mapFormsToData($forms, &$data); } These methods correspond to the two previous code blocks. The method mapDataToForms() calls setData() on all passed forms by reading the passed $data. Conversely, mapFormsToData() updates $data by reading the data of the passed forms.

types.refinement might be what you're looking for, you could combine that with for example react-final-form. it is not depending on redux anymore. a form component of react-final-form wrapped by an @observer and using an action within onSubmit callback of it to actually persist the state has worked out well for me recently.

Final Form manages its own state. You put state in, with initialValues, and you get state out, with onSubmit

Designers can group related fields into sections. If your form has more than six questions, group related questions into logical sections. Don’t forget to provide a good amount of white space between sections to distinguish them visually.Generally, if your form has more than six questions, it’s better to group related questions into logical sections. Put things together that make sense together. (Large preview)

This rule has a few exceptions: It’s helpful to validate inline as the user is typing when creating a password (to check whether the password meets complexity requirements), when creating a user name (to check whether a name is available) and when typing a message with a character limit.

Ideally, inline validation messages should appear around 500 to 1000 milliseconds after the user has stopped typing or after they’ve moved to the next field.

The US says ZIP code, whereas in Europe, it is postal code.

By asking questions, the listeners feel that they have a choice to say no and thus are not offended by your request. In Japanese, you should also ask questions when you ask for a favor.
