prismic-ts-downloader

Fetch content from Prismic via GraphQL as TypeScript files.

Installation

yarn add @downpourdigital/prismic-ts-downloader
npm i --save @downpourdigital/prismic-ts-downloader

Motivations

Typed results

Since the results are stored as static TS files, exports are automatically typed.

Painless integration of files

Files are downloaded and imported, as you would do normally, which means webpack loaders work out of the box!

Tool agnostic

prismic-ts-downloader isn't tied to a specific site generator or framework. It just puts static files in a folder. Thats it.

Usage

To get started, you have to provide a site id (YOUR-SITE-ID.prismic.io) and an output directory into which the content is downloaded.

tasks specifies a list of tasks to run, once the API is ready where a "task" is a function which returns a Promise. (this type is exported as TaskFactory for convenience)

Inside this function you have access to several helpers:

query runs a query against the API and returns a Promise resolving with the results.

asExternal flags a given url for download.

asComponent flags a given source string as TSX. This will import React into the resulting file and export the string as a React fragment.

toFile writes the given output to a file and adds all the necessary imports.

import path from 'path';
import gql from 'graphql-tag';
import { run } from '@downpourdigital/prismic-ts-download';

run({
	siteId: 'YOUR-SITE-ID',
	outDir: path.resolve( __dirname, '../content' ),
	tasks: [
		({ query, asExternal, asComponent, toFile }) => (
			query({
				query: gql`
				{
					allArticles(lang: "en-us") {
						edges {
							node {
								title
								header_image
								description
							}
						}
					}
				}
				`,
			}).then( response => {
				const output = response.data.allArticles.edges.map(
					({ node }: any ) => ({
						title: node.title[0].text,
						header_image: asExternal( node.header_image.url ),
						description: node.description.map(
							( p: any ) => p.text,
						).join( '\n' ),
					}),
				);

				toFile( 'articles', output );
			})
		),
	],
});

To integrate this into your existing build workflow, simply create a separate npm task which runs before the build task. You can run TS files directly with ts-node.

Inside your project you can now access the content like so:

import articles from '../your-specified-dir/articles';

console.log(articles);
// the type of articles is:
{
	title: string,
	header_image: string, // or whatever your image loader outputs
	description: string,
}[]

To do

  • error handling
  • private repositories
  • better docs
  • testing
