Web UI

The web user interface of ving allows you to build out complex applications using Vue 3. It starts with automatically generating pages for your ving records. We use a component library suite called PrimeVue that provides all kinds of amazing functionality and a styling library called Tailwind CSS that gives you rich power over CSS. We also provide access to all of the VueUse composables for things like reactivity within localStorage, mouse, keyboard, and other browser subsystems. But we've also got a bunch of custom components and composables to help you build your app.

Layouts

The design of your site is created using Nuxt Layouts. You can find the default layout in layouts/default.vue.

Theme

The color scheme of your site is handled through PrimeVue styled themes. You can see the existing ving theme in /app/themes/ving-theme.mjs. We recommend you create your own theme by copying that file to a new name, and then telling Nuxt that you want to use your theme in /nuxt.config.mjs.

Pages

ving is ultimately built on Nuxt, so ving pages can do anything Nuxt Pages can do.

You can automatically generate a set of pages for interacting with ving records through the Rest API by using the CLI like this:

bash

./ving.mjs record --web Foo

Note that you will need a Ving Schema, Ving Record, and Rest for Foo before the web interface can function.

That will give you a place to start, and then you can use the composables and components we provide to build out a complex app.

Icons

The Ving UI makes use if the Nuxt Icon module (which behind the scenes uses the Iconify library), which joins together many different icon libraries to give you a big selection of icons.

For example, the code for a gear icon could be: mdi:gear. And then to display that icon you could do:

html

    <Icon name="mdi:gear" color="red" />

Components

You can use any of the built in Nuxt components, or one of the 200 components from PrimeVue or these custom Ving components:

CopyToClipboard

Displays a button that allows you to copy a text string to the user's clipboard.

html

<CopyToClipboard :text="foo"/>

Props:

text - The text you wish to copy to the clipboard.
size - The size of the button. Defaults to the normal button size. Can also be lg, sm, or xs.

Crumbtrail

Displays a crumbtrail navigation.

html

<Crumbtrail :crumbs="breadcrumbs" />

Props:

crumbs - An array of objects containing:
- label - A string for the page name.
- to - A string of the page to navigate to.

DarkModeSelector

Allows the user to switch between light or dark mode.

html

<DarkModeSelector/>

Dropzone

Creates a user interface for uploading S3Files. It handles the resizing of images on the client side, restriction of file types on the client side, requesting the presigned upload URL, uploading the file to S3. The only thing you need to do is specify via afterUpload what happens to the file after the user uploads it.

html

<Dropzone :acceptedFiles="['pdf','zip']" :afterUpload="doThisFunc"></Dropzone>

Props:

acceptedFiles - An array of file extensions that S3File should accept. Defaults to ['png','jpg']. This can and should be automatically filled by a meta.acceptedFileExtensions property from a Ving Record when dealing with S3Files. It is set by the relation.acceptedFileExtensions attribute in a Ving Schema. For example:

html

<Dropzone :acceptedFiles="user.meta?.acceptedFileExtensions?.avatar" />

afterUpload - Required. A function that will be executed after upload. This function should then call the appropriate import endpoint to post process and verify the file.
info - A string that will be displayed inside the dropzone box. Useful to give the user some insights about the nature of the files you will allow such as size or dimension contstraints.
maxFiles - An integer of the maximum number of files the user is allowed to select for upload. Defaults to unlimited.
maxFilesize - An integer of the maximum file size in bytes that the user is allowed to upload. Defaults to 100000000.
resizeHeight - The height in pixels to resize the uploaded image to. Defaults to leaving the size as it is.
resizeMethod - How should a resize of an uploaded image happen? The first option is contain, which is the default, and that means that the image will retain its aspect ratio, but will not exceed the bounds of resizeWidth and resizeHeight. The second option is crop which will crop the middle portion of the image to the bounds of resizeWidth and resizeHeight and discard anything outside those bounds.
resizeQuality - A float representing a percentage of quality that should be applied when resizing jpg and webp images during upload. 0.6 would represent 60% quality. Defaults to 1.
resizeWidth - The width in pixels to resize the uploaded image to. Defaults to leaving the size as it is.

FieldsetItem

A fieldset element within a FieldsetNav.

html

<FieldsetItem name="Foo">
Forms go here...
</FieldsetItem>

Props:

name - The name of the field set.

FieldsetNav

An inline page nav for a large scrollable form to be divided up into sections using FieldsetItem.

html

<FieldsetNav>
    <FieldsetItem name="Content">...</FieldsetItem>
    <FieldsetItem name="Taxonomy">...</FieldsetItem>
    <FieldsetItem name="Privileges">...</FieldsetItem>
</FieldsetNav>

Form

A form element to allow coordination of validation of inputs.

html

<Form :send="someFunc()">...</Form>

Props:

send - A function that should be executed once the form is sumbmitted and fields have been validated.

FormInput

Generate the appropritate form field based upon input types. This also handles labeling and error handling in an automated fashion, and thus is generally preferable to using the individual form inputs.

html

<FormInput name="username" v-model="user.username" />

Props:

label - A form label for proper ARIA compliance.
type - Defaults to text but can also be textarea, password, number, markdown, select, switch or email.

subtext - Add a small message beneath the field. Note, only shows if the field is not required, or is required and has a value, or isn't invalid.
append - Appends an input group to the end of the field. Example: .00
prepend - Prepends an input group to the front of the field. Example $
autocomplete - Sets the browser's autocomplete settings for password fillers and whatnot. Defaults to off.
v-model - What Vue reactive variable should this be connected to? Required.
placeholder - Text to be displayed if the input is empty.
required - A boolean that defaults to false, but if true will not allow the form to be sent if empty.
step - An amount to increment a number type field. Defaults to 1.
options - An array of objects that is used when type is select:
- label - The human readable label for the value.
- value - The value to select. Can be string, number, or boolean.
mustMatch - An object containing:
- field - A label for a field or some other attribute such as Password.
- value - The value that this field must match.
class - A CSS class that should be applied to the field.
coerce - A function that accepts a the value of this field, manipulates it in some way, and returns it. By default it just returns the value as it is entered.

Slots:

prepend - Same thing as the prepend property above, but allows you to insert HTML not just text.
append - Same thing as the append property above, but allows you to insert HTML not just text.

FormLabel

An ARIA compliant label for a form field. In general you wouldn't use this directly, but via the label prop of FormInput.

html

<FormLabel id="foo" label="Foo" />

Props:

label - The text to display to the user.
id - The unique id of the form field this label refers to.

ManageButton

Sometimes you need to list a bunch of management functions in a tight space, like in a DataTable. This component does exactly that.

html

<ManageButton severity="primary" :items="[
    { icon:'ph:eye', label:'View', to:`/foo`},
    { icon:'ph:pencil', label:'Edit', to:`/foo/edit`},

- label - Required. The text to display to the user.
- to - Optional. A URL to link to.
- action - Optional. A function that will trigger on click.

MarkdownInput

Props:

id - A required string that is unique on the page.
v-model - A reference to the field that will be edited.
placeholder - A string to display before there is any text.

html

<MarkdownInput v-model="description" id="foo" />

html

<UserAvatar :user="user" />

UserProfileLink

Wraps the UserAvatar component in a NuxtLink pointing to the user's profile page.

Composables

Composables are reactive data functions that can only be used in script setup, other composables, or lifecycle hooks.

Each of these also has documentation of how to use them in the form of JSDocs in the source code.

useAdminLinks()

Returns a data structure for use with the PanelNav component.

const links = useAdminLinks();

useCurrentUser()

Gets you the currently logged in user.

const user = useCurrentUser();
if (await user.isAuthenticated()) {
    // do logged in user stuff
}

It also triggers 2 window events for when the user logs in or out.

    window.addEventListener('ving-login', (event) => {
        // do something after login
    });
    window.addEventListener('ving-logout', (event) => {
        // do something after logout
    });

useMessageBus()

Connects the browser to the server's message bus. It establishes a connection between your browser and the server, so it needs to be installed in an onMounted() handler in your layouts.

onMounted(() => {
    useMessageBus();
})

useNotify()

Allows you to notify the user via toasts.

    const notify = useNotify();
    notify.info('Just wanted to let you know');
    notify.warn('You might want to get concerned');
    notify.error('Be afraid');
    notify.success('Totally did it');
    notify.notify('info', 'Hello');

You would then use the Notify Component in your layout.

html

<Notify />

useRest()

A wrapper around the Nuxt composable $fetch() that allows for streamlined fetches, but integrate's with ving's subsystems.

const response = useFetch(`/api/${useRestVersion()}/user`);

useRestVersion()

Returns the current rest version number from ving.json for when you are manually specifying URLs to rest services. such as this:

useRest(`/api/${useRestVersion()}/user`);

useUserSettingsButtons()

Returns a data structure for use with the PanelNav component.

const buttons = useUserSettingsButtons();

useUserSettingsLinks()

Returns a data structure for use with the PanelNav component.

const links = useUserSettingsLinks();

useSystemWideAlert()

Generally not something you'd need to use, but you will interact with it through the admin UI for the system wide alert, but it is used by the SystemWideAlert component.

const swa = useSystemWideAlert();
onMounted(async () => {
    swa.check();
}

useThrobber()

Whenever there is an interaction with the API via the useRest() composable it will update the throbber store. It is then used by the Throbber component.

You may also wish to trigger it for other background actions that are happening so that your user knows something is going on at the moment. Maybe if you're processing a file for export, or if you have some heavy calculations going on, or if you're waiting on a web worker.

    const throbber = useThrobber();
    throbber.working();
    throbber.done();

useVingKind()

A client for interacting with server-side ving kinds through the Rest API.

const users = useVingKind({
    listApi : `/api/${useRestVersion()}/user`,
    createApi : `/api/${useRestVersion()}/user`,
    query: { includeMeta: true, sortBy: 'username', sortOrder: 'asc' },
    newDefaults: { username: '', realName: '', email: '' },
});
await users.search();
onBeforeRouteLeave(() => users.dispose());

useVingRecord()

A client for interacting with server-side ving records through the Rest API.

const id = route.params.id.toString();
const user = useVingRecord<'User'>({
    id,
    fetchApi: `/api/${useRestVersion()}/user/${id}`,
    createApi: `/api/${useRestVersion()}/user`,
    query: { includeMeta: true, includeOptions: true },
    onUpdate() {
        notify.success('Updated user.');
    },
    async onDelete() {
        await navigateTo('/user/admin');
    },
});
await user.fetch()
onBeforeRouteLeave(() => user.dispose());

Utilities

These are UI utility functions that will make your life easier.

Each of these also has documentation of how to use them in the form of JSDocs in the source code.

Date Formatting

Date formatting tools based upon date-fns.

determineDate("2012-04-23T18:25:43.511Z") // a Date() object
formatDateTime(new Date()) // August 2, 2023 at 4:03pm
formatDate(new Date()) // August 2, 2023
formatTimeAgo("2012-04-23T18:25:43.511Z") // 3 years ago

enum2label()

Converts an enum value into an emum label as defined in a ving schema.

enum2label(enum2label('archived', [{value: 'archived', label:'Is Archived'}, {value: 'not_archived', label:'Not Archived'}]))
