海外TECH	DEV Community	Remix & Shopify: Circumvent Shopify’s APIs and go open source	https://dev.to/medusajs/remix-shopify-circumvent-shopifys-apis-and-go-open-source-36g2	Remix amp Shopify Circumvent Shopify s APIs and go open sourceShopify seems to acknowledge that open source is what developers want First they gave us Hydrogen and now they went even further by joining forces with Remix While good news some might still want to go all in on open source and customizability by building with a setup that is fully open source across the entire stack In this article you ll learn how you can circumvent Shopify to get a fully functional ecommerce setup with Remix using only open source tools Win win win How it ll workFirst we will replace Shopify s functionality by combining the power of two of the most popular open source projects Medusa the leading open source ecommerce platform for developers allowing for great customization and is built with JavascriptStrapi the leading open source CMS built for developers likewise highly customizable and also built in JavascriptIn this tutorial you ll learn how to build an ecommerce storefront using Remix and powered by Medusa amp Strapi to avoid a full Shopify backend You can find the source code for this article in this repository Below a sneak peak to the final result PrerequisitesNode v or aboveYarn is recommended but you can also follow along with npm RedisMedusa CLI To install the CLI run yarn global add medusajs medusa cli Set Up Strapi Install the Templatenpx create strapi app strapi medusa template shahednasser strapi medusa templateThis creates a folder named strapi medusa in your project Once the installation is complete the Strapi development server will start on port localhost A new page will also open in your default browser to create a new admin user and log in After you have logged in you can access your Strapi Dashboard Change Authorization Settings for the UserYour Medusa sever will require the credentials of a Strapi User in order to seed Strapi with mock data To create a new user go to Content Manager then choose User under Collection Types Click on the Create new entry button at the top right This opens a new form to enter the user s details Enter the user s username email and password Once you re done click on the Save button at the top right Next go to Settings →Roles →Authenticated and select all the permissions and hit save Set up MedusaTo initiate your Medusa server run the following command medusa new medusa server seedThe seed flag creates an SQLite database and seeds it with some demo data Change to the medusa server directory and go to medusa config js Change the exported object at the end to enable Redis module exports projectConfig redis url REDIS URL The default Redis connection string is redis localhost but if you have made changes to it go to the env file and add the following REDIS URL lt YOUR REDIS URL gt Where lt YOUR REDIS URL gt is your connection string Additionally since the Remix storefront runs on localhost you have to add an environment variable STORE CORS that sets the URL of the storefront Add the following in env STORE CORS http localhost Install Strapi PluginTo install the Strapi plugin run the following command in your Medusa server s directory yarn add medusa plugin strapiThen add the following environment variables STRAPI USER lt STRAPI IDENTIFIER gt STRAPI PASSWORD lt STRAPI PASSWORD gt STRAPI PROTOCOL httpSTRAPI URL lt STRAPI URL gt OptionalSTRAPI PORT lt STRAPI PORT gt OptionalWhere lt STRAPI IDENTIFIER gt is either the email address or username of the user you created in the previous step lt STRAPI PASSWORD gt is the password of the user you created in the previous step lt STRAPI PROTOCOL gt is the protocol of your Strapi server Since you re using a local Strapi server set this to http The default value is https lt STRAPI URL gt is the URL of your Strapi server By default the URL is localhost lt STRAPI PORT gt is the port the Strapi server runs on By default the port is Finally open medusa config js and add the following new item to the plugins array const plugins resolve medusa plugin strapi options strapi medusa user process env STRAPI USER strapi medusa password process env STRAPI PASSWORD strapi url process env STRAPI URL optional strapi port process env STRAPI PORT optional strapi protocol process env STRAPI PROTOCOL optional Test IntegrationMake sure the Strapi server is still running If not you can run the following command to run the Strapi server in the directory of the Strapi project yarn developMake sure your Redis server is up and running as well Then in the directory of your Medusa server run the following command to start the Medusa server yarn startThis will start your Medusa server on localhost You ll see that product created events have been triggered along with similar events This will update Strapi with the demo products you seeded Add CMS Pages in StrapiYou will now use Strapi to manage content on your storefront s homepage You will be able to control three things from Strapi after this implementation the hero text that will appear at the top of the storefront the subheading below the hero text and the list of products shown on the homepage On your Strapi dashboard go to Content Type Builder under Plugins in your Strapi Dashboard This is where you can define the model schema for your content Click on “Create new single type under “Single Types Enter the display name as “Home Page if you have used another you will have to use the appropriate API ID for it later and hit continue Next select the component field and give it the display name “Hero Text and a category homepage click create “homepage under the category Then click on configure the component Then give it the name hero text in the next step and click Finish Go to the Hero Text component under Homepage in components and create three text fields named start text mid text and end text Here the three text fields have been added because later on in the article you will give a special underline to the mid text to highlight it Go back to the Home Page type under single types and add a relation field to products The relation should be “homepage has many products Give it a field name products list Finally add a text field heading Save your changes in the homepage content type This is what your homepage content type should look like Next go to Settings →Users amp Permissions Plugin →Roles →Public and enable find permission for the homepage and product type Hit save Now go to the content manager and under the Home Page add your hero text and the products you wish to display under the relations section to the right Hit save and then publish Set up the Remix StorefrontIn this section you ll set up the ecommerce storefront with Remix Remix has three official pre built templates for you to use depending on your needs but you can also start with a basic one or create your own Set up RemixTo setup a Remix app do this in a separate directory from medusa server and strapi medusa run the following command npx create remix latest my storefrontIt will ask you a few questions Choose Just the basics then choose your preferred hosting platform you can choose Remix App Server if you are unsure choose typescript and no for npm install if you wish to use yarn Then change to the my storefront directory and install dependencies with yarn cd my storefrontyarn install Configure Tailwind CSSInstall Tailwind CSS to design the UI element yarn add D tailwindcss postcss autoprefixer concurrentlyRun npx tailwindcss init to create your tailwind config js file Then set its content to the following type import tailwindcss Config module exports content app js ts jsx tsx theme extend plugins Also change the scripts in your package json scripts build npm run build css amp amp remix build build css tailwindcss m i styles app css o app styles app css dev concurrently npm run dev css remix dev dev css tailwindcss w i styles app css o app styles app css Then create the file styles app css with the following content tailwind base tailwind components tailwind utilities Lastly add this to your app root tsx after the list of imports import styles from styles app css export function links return rel stylesheet href styles You can now use Tailwind CSS in your app Connect Storefront to Medusa ServerOnce this is done let s connect your storefront to your Medusa server First you need to install a few packages with the following command yarn add medusa react react query medusajs medusaThe medusa react library uses react query as a solution for server side state management and lists the library as a peer dependency In order to use the hooks exposed by medusa react you will need to include the MedusaProvider somewhere up in your component tree The MedusaProvider takes a baseUrl prop which should point to your Medusa server Under the hood medusa react uses the medusa js client library built on top of axios to interact with your server In addition because medusa react is built on top of react query you can pass an object representing react query s QueryClientProvider props which MedusaProvider will pass along You also need to wrap your app in a CartProvider since that will let you use the cart functionalities provided by Medusa which you will do later Create a file app lib config ts This file will contain your medusaClient which will let you use Medusa s Javascript client in your app import Medusa from medusajs medusa js import QueryClient from react query const MEDUSA BACKEND URL http localhost const STRAPI API URL api const queryClient new QueryClient defaultOptions queries refetchOnWindowFocus false staleTime retry const medusaClient new Medusa baseUrl MEDUSA BACKEND URL maxRetries export MEDUSA BACKEND URL STRAPI API URL queryClient medusaClient Now go to your app root tsx and import the required packages import MedusaProvider CartProvider from medusa react import MEDUSA BACKEND URL queryClient from lib config You can also edit the meta here to change your metadataexport const meta MetaFunction gt charset utf title New Remix App viewport width device width initial scale Below this you will see the App component In the returned JSX add the MedusaProvider and CartProvider with some base styles to the body return lt html lang en gt lt head gt lt Meta gt lt Links gt lt head gt lt body className bg black text slate overflow x hidden justify center flex gt lt MedusaProvider queryClientProviderProps client queryClient baseUrl MEDUSA BACKEND URL gt lt CartProvider gt lt Outlet gt lt ScrollRestoration gt lt Scripts gt lt LiveReload gt lt CartProvider gt lt MedusaProvider gt lt body gt lt html gt Display Home Page from StrapiThe data for your home page is available on the Strapi endpoint localhost api home page add populate to also show the nested products It returns an object with the data amp meta arrays You don t have to care about the meta what you should really care about is data it contains all the content you entered in your Strapi Dashboard First create the file app types StrapiResponse ts with the following content StrapiResponse tsexport type StrapiResponseType data id number attributes createdAt Date updatedAt Date publishedAt Date hero text id number start text string mid text string end text string products list data Array lt StrapiProductData gt heading string meta export type StrapiProductData id number attributes medusa id string title string subtitle string null description string handle string is giftcard boolean status draft proposed published rejected thumbnail string discountable boolean weight number product length null width null height null hs code null origin country null mid code null material string null createdAt Date updatedAt Date This is the format in which your data is returned from the Strapi API Next create a utility function to fetch your content from the Strapi API Create a file app models home server ts with the following content home server tsimport STRAPI API URL from lib config import type StrapiProductData StrapiResponseType from types StrapiResponse export const getHomePageData async gt const homePage StrapiResponseType await await fetch STRAPI API URL home page populate json const data homePage const attributes data const heroText attributes hero text const products attributes products list data const smallHeading attributes heading const homePageData heroText products smallHeading return homePageData export type homePageDataType heroText id number start text string mid text string end text string products StrapiProductData smallHeading string In the getHomePageData function you should only return the data you need on your home page In the above code sample you will notice that in the import statement is used this is because it is the alias set for the app directory set in the tsconfig by default in Remix if you wish you can change it at your convenience All files inside the app routes directory will be a route For example app routes store tsx will contain the store route Next go to app routes index tsx and create a loader function import getHomePageData homePageDataType from models home server export const loader async gt const homePageData await getHomePageData return homePageData To use the response you received from the loader function you will use the useLoaderData hook from Remix inside the Index component import useLoaderData from remix run react export default function Index const heroText products smallHeading useLoaderData lt homePageDataType gt Here homePageData was destructured and brought in using useLoaderData now you can use it on your page Then change the returned JSX to the following export default function Index return lt div className px sm px md px pt max w rem flex grow w screen gt Hero Section lt div gt lt h className text rem sm text xl lg text xl xl text xl relative font medium lg leading xl leading gt heroText start text heroText mid text split map text gt lt span key text className text gray gt lt span className relative gt text lt div className h bg emerald w full absolute bottom left inline block gt lt span gt lt span gt heroText end text lt h gt lt div gt lt div gt heroText start text brings data from the start text text field under the hero text component you made in Strapi Similarly heroText mid text and heroText end text are from mid text and end text fields from Strapi respectively Then mid text has been split so that each word gets a uniform underline in case there are multiple words you will see it happen a bit later in the homepage UI To display your products create the file app components productCard tsx with the following content import Link from remix run react interface ProductCardType image string title string handle string export default function ProductCard image title handle ProductCardType return lt Link to products handle gt lt div className flex flex col space y p hover bg slate hover bg opacity cursor pointer active scale transition ease in out duration gt lt img src image alt gt lt h className pt text white text xl gt title lt h gt lt div gt lt Link gt The Link comes from Remix and will help you redirect to the products page The handle prop which is available in Medusa products will be used as a slug Now getting back to your app routes index tsx you will map your Strapi response products to the page Do this just below your hero section import ProductCard from components productCard export default function Index return lt div className px sm px md px pt max w rem flex grow w screen gt lt div className flex flex col items center pt pb gt lt h className text xl sm text xl lg text xl pb text white gt smallHeading lt h gt lt div className grid grid cols xl grid cols gap x gt products map attributes gt lt ProductCard key attributes medusa id image attributes thumbnail handle attributes handle title attributes title gt lt div gt lt div gt lt div gt Test HomepageTo test out your homepage start your Remix development server with yarn dev make sure that your Medusa and Strapi servers are already running Your app is ready at localhost and it will look like the following Implement Add to Cart Functionality with MedusaTo add your products to the cart you first need to associate a cart with the customer To do this you can create a wrapper around your app that checks if a cart has already been initialized or need to be created and does the needful Create the file app components outletContainer tsx with the following content import useCart from medusa react import ReactNode useEffect from react import medusaClient from lib config interface OutletContainerType children ReactNode export default function OutletContainer children OutletContainerType const setCart useCart useEffect gt const localCartId localStorage getItem cart id localCartId medusaClient carts retrieve localCartId then cart gt setCart cart medusaClient carts create then cart gt localStorage setItem cart id cart id setCart cart return lt div gt children lt div gt You are using medusa react s useCart hook setCart will set your cart globally You can then use it anywhere in your app The outletContainer will also save cart localStorage so that the added items persist even when the user returns You will also need to show toast notifications when a product is added to the cart Install react hot toast to do this yarn add react hot toastNow go back to your app root tsx and wrap your lt Outlet gt with OutletContainer Also add lt Toaster gt from react hot toast that will let you show notifications import OutletContainer from components outletContainer import Toaster from react hot toast export default function App return lt CartProvider gt lt OutletContainer gt lt Outlet gt lt OutletContainer gt lt Toaster gt lt CartProvider gt Create Product PageIn this section you ll create a product page When you are deploying to production you can t make a separate page for each of your products so you will create a dynamic page that will run according to your product s handle In Remix you will name your dynamic pages as slug tsx You will need to get the handle from the URL of your page you can do that with a loader function but it s much simpler to use useParams hook Create the file app routes products slug tsx with the following content import useParams from remix run react import useCart useCreateLineItem useProducts from medusa react export default function ProductSlug const slug useParams slug is getting your page s slug from your URL for example in localhost products sweatshirt the slug is sweatshirt remember you passed in the handle in your ProductCard component Next fetch your product from Medusa using the useProducts hook and add it to the UI export default function ProductSlug const products useProducts handle slug if products return lt div gt lt div gt you can use skeleton loader here instead const product products return lt div className flex flex col items center lg justify between lg flex row px sm px md px pt max w rem flex grow w screen gt lt img src product thumbnail className h w auto gt lt div gt lt h className text xl pb text white gt product title lt h gt lt p className w gt product description lt p gt lt div gt lt div gt Here the useProducts hook was used and passed the slug While the product is being loaded you show an empty div you can use a skeleton loader instead Finally you use the first item returned by the useProducts hook which is the product that has the handle in the page s URL Please notice that the title and description are used here from the Medusa server since the Strapi plugin supports two way sync So whenever you make changes to the products in Strapi they re reflected on the Medusa server as well You can alternatively show the CMS data for the product from Strapi instead You also need to show the prices for your customers according to their region To do this create the file app lib formatPrice ts import formatVariantPrice from medusa react import type Cart from medusa react dist types import type ProductVariant from medusajs medusa export const formatPrice variant ProductVariant cart Cart gt if cart return formatVariantPrice variant variant region cart region You use the formatVariantPrice function here from medusa react This formats the price according to your user s region and the product variant selected Then use it in app routes products slug tsx import formatPrice from lib formatPrice export default ProductSlug const cart useCart return lt div className flex flex col items center lg justify between lg flex row px pb sm px md px pt max w rem flex grow w screen gt lt img

xl text white pt gt formatPrice product variants cart lt p gt lt div gt lt div gt Next create a function to add to the cart and push notifications import toast from react hot toast export default function ProductSlug const mutate useCreateLineItem cart id const addItem gt mutate variant id products slice variants id quantity onSuccess gt toast Added to Cart The useCreateLineItem hook lets you add items It requires a cart ID The addItem function will add the product to the cart and then show a toast notification Add the button that will run this function on click in the returned JSX export default function ProductSlug return lt div className flex flex col items center lg justify between lg flex row px sm px md px pt max w rem flex grow w screen gt lt img src product thumbnail className

lt p gt lt button className p rounded md w full bg slate bg opacity mt cursor pointer active scale transition ease in out duration onClick gt addItem gt Add item lt button gt lt div gt lt div gt The last step is to add a navigation bar to make it easy to navigate to the cart Create the file app components topNavigator tsx with the following content import Link from remix run react export default function TopNavigator return lt nav className flex w screen fixed top right left items center py flex row justify between px sm px md px z bg black gt lt Link to className text xl gt MRS lt Link gt lt

export default function App return lt CartProvider gt lt OutletContainer gt lt TopNavigator gt lt Outlet gt lt OutletContainer gt lt CartProvider gt Test Product PageTo test out your product page restart your Remix server make sure Strapi and Medusa servers are already running Click on any of the products on your homepage and you will be able to see the details Create Cart PageNow you will create your very final cart page Create the file app routes cart tsx with the following content import useState useEffect from react import medusaClient from lib config import type Cart as CartType from medusa react dist types export default function Cart const cart setCart useState lt CartType gt useEffect gt medusaClient carts retrieve localStorage getItem cart id then cart gt setCart cart
