@nrk/sanity-plugin-nrkno-odd-utils

This lib expands on the principles of nrkno-sanity.

nrkno-odd-utils (odd = option driven design) contains a handful of utility functions and classes for working with Sanity custom components.

See docs about option driven design for more.

Installation

Yarn

yarn add @nrk/sanity-plugin-nrkno-odd-utils

npm

npm install --save @nrk/sanity-plugin-nrkno-odd-utils

Usage

Easily decorate and reuse built-in Sanity inputs by delegating to NestedFormBuilder. It is imperative that we unset the inputComponent in the type (or unset the option used by input-resolver.ts).

Functions available as module imports:

import {
    unsetOption, 
    unsetInputComponent,
    useUnsetOption, 
    useUnsetInputComponent, 
    NestedFormBuilder
} from '@nrk/sanity-plugin-nrkno-odd-utils'

Example - inputComponent

Given a schema with an input component:

const schemaOrField = {
  name: 'schemaOrField',
  inputComponent: CustomComponent,
}

We can decorate a custom heading over a standard sanity input (regardless of type), like so:

// CustomComponent.tsx
import React, {forwardRef, Ref} from 'react';
import {useUnsetInputComponent, NestedFormBuilder} from '@nrk/sanity-plugin-nrkno-odd-utils';

export const CustomComponent = forwardRef(function CustomComponent(props, ref) {
    // IMPORTANT: leaving out will cause the browser to lock up in an infinite loop
    const type = useUnsetInputComponent(props.type);
    return <div>
        <h4>A custom heading</h4>
        <NestedFormBuilder {...props} ref={ref} type={type}/>
    </div>;
});

Example - option

Given a schema with an option, and an input-resolver.js file defined in sanity.json:

// schema-file.js
const schemaOrField = {
  name: 'schemaOrField',
  option: {
      custom: true
  }
}

// input-resolver.js
function resolveInput(schema) {
    if(schema.options?.custom) {
        return CustomComponent
    }
}

We can decorate a custom heading over a standard sanity input (regardless of type), like so:

// CustomComponent.tsx
import React, {forwardRef, Ref} from 'react';
import {useUnsetOption, NestedFormBuilder} from '@nrk/sanity-plugin-nrkno-odd-utils';

export const CustomComponent = forwardRef(function CustomComponent(props, ref) {
    // IMPORTANT: leaving out will cause the browser to lock up in an infinite loop
    const type = useUnsetOption(props.type, 'custom');
    return <div>
        <h4>A custom heading</h4>
        <NestedFormBuilder {...props} ref={ref} type={type}/>
    </div>;
});

Unit testing components using NestedFormBuilder

NestedFormBuilder extends FormBuilderInput. FormBuilderInput is a Sanity component that uses non-standard import syntax that does not play well with Jest (import x from 'part:xyz').

See NestedFormBuilder.test.ts for examples on how to mock FormBuilderInput, and check which props passed to FormBuilderInput during render.

This is useful when unit-testing that props.type was modified correctly for instance.

Develop

This plugin is built with sanipack.

Test the build

Inside this directory run

npm run build 
yarn link

Then

cd /path/to/sanity-studio
yarn link @nrk/sanity-plugin-nrkno-odd-utils

The change to yarn is intentional , since that is what Sanity Studio uses.
