Contentful REST API

Introduction

import { ContentfulFetcher } from "@buildinams/contentful-rest";

export const cfClient = new ContentfulFetcher();

Installation

Install this package with npm.

npm i @buildinams/contentful-rest

Usage

import {
	ContentfulFetcher,
	ContentfulAdaptor,
} from "@buildinams/contentful-rest";

const Adaptor = new ContentfulAdaptor({});

export const cfClient = new ContentfulFetcher({
	config: { spaceId, accessToken, previewToken, environment },
	adaptor: Adaptor,
	isPreview: IS_DEVELOPMENT,
});

const fetchData = async (args: DataTypeArgs) => {
	const data = await cfClient.getEntries({ query, options });
};

ContentfulFetcher

import { createClient } from "@buildinams/contentful-rest";

export const cfClient = new ContentfulFetcher({
	config: { spaceId, accessToken, previewToken, environment },
	adaptor: Adaptor,
	isPreview: IS_DEVELOPMENT,
});

Create client creates a helper function that is able to send GraphQL queries to your Contentful space. The expected arguments are;

• config.accessToken - Access token of your Contentful space
• config.previewToken - Preview token to be able to query draft data
• config.spaceId - Space to get data from
• config.environment - Optional; Environment to query, default to; "master"
• adaptor - Optional; Modify data to match the structure required for your application
• isPreview - Optional; Flag to fetch all data as preview, convenient for development environments

ContentfulAdaptor

import { ContentfulAdaptor } from "@buildinams/contentful-rest";
const Adaptor = new ContentfulAdaptor({
	fieldAdaptors: {
		Asset: assetAdaptor,
	},
	contentAdaptors: {
		BlockMedia: blockMediaAdaptor,
	},
	pageAdaptors: {
		Homepage: homepageAdaptor,
	},
});

This generates a JavaScript class that gives you the option to adapt the data. Expected arguments;

• fieldAdaptors - Adaptors to run on the specific fields, for example the "Asset" field.
• contentAdaptors - Content adaptors run recursively over the provided data. When an object matches the pattern: { __typename: {key} } it will run the adaptor with the matching {key}.
• pageAdaptors - Page adaptors only run top level. These can be used if you want to format the initial data but you don't want to run to run them when they are referenced. Example; we want a pageLayout to contain all data but when referenced in a cta we don't want the page adaptor.

Adaptors

The concept of adaptors are generics that modifiy certain data by content type (__typename). Often these can follow the structure below;

const blockMediaAdaptor = (data: ContentfulQueryResponse) => {
	return {
		type: data.file.fileType,
		src: data.src,
		ratio: data.height / data.width,
	};
};

export type BlockMedia = ReturnType<typeof blockMediaAdaptor>;

Within your application you can then use the BlockMedia type to link back to the type of data you expect to receive.

getIndicatorProps

import { getIndicatorProps } from "@buildinams/contentful-rest/getIndicatorProps";
<h1 {...getIndicatorProps({ entryId: entry.sys.id, fieldId: "title" })}>
  {entry.title}
</h1>;

A small helper function to get indicator mode in Contentful preview mode. Expected arugments;

• entryId - ID of the linked content entry, usually entry.sys.id
• fieldId - Name of the field that's displayed
• locale - Optional; Locale of the displayed entry
