Demo Store with Commerce.js and Next.js

Demo Store with Commerce.js and Next.js 🛍️💳

A high-fidelity fully-fledged eCommerce demo store built using the Commerce.js SDK and Next.js with live deployment to Netlify.



This README will guide you in getting up and running with a fully-fledged eCommerce template. We have configured this template for you to one-click deploy directly to Netlify. Alternatively, you can manually deploy to your choice of hosting platform.

For a full detailed tutorial on building this JAMstack eCommerce application, please head on over here.


  • IDE or code editor of your choice
  • Node (v8.2.0 or higher)
  • NPM or Yarn
  • Chec CLI yarn global add @chec/cli


Create a Chec account.

Now that you’ve installed Chec CLI globally, you will be able to access the list of chec [COMMANDS], one of which is registering for a Chec account. Let’s go ahead and get that set up!

# Open the Chec registration page in your browser
chec register

Follow the rest of the walk-through to set up your merchant details. Alternatively, you can go here to register for a Chec account.

One-click Deploy with Netlify (recommended)

The one-click deploy allows you to connect Netlify to your GitHub account to clone the commercejs-nextjs-demo-store repository and deploy it automatically. Be sure to go to Netlify and sign up for an account before clicking the deploy button.

Deploy to Netlify button

By clicking the above button, you will be navigated to the Netlify’s direct deploy page with the project’s repository passed as parameters in the url. Click the Connect to GitHub button, name your repository and enter in this public key in the Chec Public Key input. Please note that for the purpose of getting you up and running with a live deploy preview of the demo store, we provided you with the Public Key from our demo merchant account. Now, save & deploy your site.

Please note the initial build will fail if you enter in your public key instead of the provided demo merchant key. The one-click deploy is meant for presentation purposes to spin up a quick deploy. Using your merchant account would mean you would need to have the appropriate data such as multiple assets and categories associated with your products. If you would like to use your merchant account, please follow the manual setup steps below.

Manual setup and Netlify deployment

Manual setup involves cloning the repo into your local environment, seeding the provided sample data into your Chec account and deploying to Netlify.

STEP 1. Clone the repo and install dependencies

# Clone the repository locally, optionally rename the repo, change into the directory
git clone https://github.com/chec/commercejs-nextjs-demo-store.git chec-store 
# Change into the directory and install dependencies
cd chec-store && yarn

STEP 2. Set up your environment variables

Replace the sample .env.example dotenv file at the root of the project to store your Chec public_key as well as your secret_key.

# Copy from source file to destination file .env
cp .env.example .env

You can access your API key under in your Chec dashboard setup, then navigate to the Develop tab to copy your Public Key and Secret Key. Replace the provided NEXT_PUBLIC_CHEC_PUBLIC_KEY with your own and fill in your CHEC_SECRET_KEY in the .env file. The secret key is necessary for the seed script to have the proper permission to seed the sample data in /seeds into your Chec account. Remove the secret key once the data is seeded.

# .env

# Fill in your public key and secret key
# Secret key is used with chec/seeder to access your Chec account to seed it with sample data

This file is meant to not be committed to source control and also will be hidden in file browsers.

STEP 3. Seed the data necessary to power your Chec store and start your development environment (necessary for initial setup).

# Seed data in /seeds into your Chec account
yarn seed
# Run your development environment on http://localhost:3000
yarn dev

Now head on over to http://localhost:3000 after starting your development, your site should now be populated with the sample data!

If you are replacing the sample products or categories, you can customize your own categories images under `public/images/collection. See more info on data customization below.

STEP 5. Make any necessary changes you need and push the code to a repository on Github or your choice of platform.

STEP 6. Deploy your site

Be sure to sign up for a Netlify account and log in to it. Click the New site from Git button and give access to select your repo. Your build settings are automatically filled out for your from the netlify.toml in the template. To enter your environment variables, click Show advanced then New variable and fill in the key input as NEXT_PUBLIC_CHEC_PUBLIC_KEY and the value input with your Public Key. You can access your API key in your Chec dashboard under Setup, then navigate to the Developer tab to copy your Public Key

Now go ahead and click the "deploy site" to see your live site!

Setup using Chec CLI demo-store command

This command will download this example project from GitHub and initialise it on your machine. You will be free to edit the downloaded code and play around with Commerce.js afterwards.

STEP 1. Install the Chec CLI

npm install -g @chec/cli
# or
yarn add -g @chec/cli

STEP 2. Create a demo store

chec demo-store

When prompted to choose a demo store from the list, choose "commercejs-nextjs-demo-store". This command will also seed some sample data to your Chec account. For more information, see the Chec CLI documentation.

Caveats with data customization (IMPORTANT)

Because this project is a fully fledged storefront showcasing a custom design and user flow, there are certain caveats you will run into if you customize your data in the Chec Dashboard. One gotcha is with the categories data in the UI: The categories feature images are added in the Chec API as meta data. If you add new or edit the seeded sample categories data, you can customize the categories feature image by replacing your image assets under public/images/collection. The file names will need to remain the same. If you plan on changing the files names or add new categories, you'll need to add new meta data. The app will expect the below inventory setup in order to build and render the components, so if you'd like to customize with your inventory in the backend make sure you:

Commerce.js features

This demo store uses a range of features provided by Commerce.js and powered by the Chec Dashboard.


The shopping cart uses the Commerce.js cart API. Carts are persisted for up to 30 days, and Commerce.js automatically remembers carts for visitors.

The checkout

Commerce.js provides many tools to streamline checkout implementations. The checkout in this demo store makes use of:

  • Commerce.js's country and region APIs,
  • the shipping methods API, and
  • the discounts API (for validating and applying discounts at the checkout).


Commerce.js provides inbuilt functionality for supporting customer logins without any server side code. This demo store features an existing customer login page, and provides detail about previous orders. The customer information is also used to pre-populate the checkout with known customer details.

Payment gateways

This demo store is configured with the Chec "test gateway" out of the box, which provides a handy payment option while testing your storefront. Additionally, Stripe Elements support is included if Stripe is configured on the Chec Dashboard.

Commerce.js <> Stripe integration documentation

Enabling Stripe

You must enable Stripe in the Chec Dashboard by following the instructions provided. You may add your sandbox keys for Stripe, and use a sandbox Chec public API key to test with Stripe. Both the Chec public API key, and the Stripe "publishable" key are configured in the .env file. See step two of "Manual setup and Netlify deployment"

Customization and Extendability

Fork this project to customize and extend the demo however you want. Here are some ideas of what you can do and directions you can take eCommerce.

  • Add shipping zones and enable shipping options in each product
  • Customizing the styling
    • All global styles are done using SASS and Bootstrap
  • A/B testing checkout designs and flows
  • Integrating other backend tools like Content Management Systems, Customer Support, Fulfillment services, and more
  • Fetching real client reviews from review APIs
  • Adding search functionality
  • Leveraging webhooks to automate post checkout actions

NBB: Ad-hoc CLJS Scripting on Node.js


Not babashka. Node.js babashka!?

Ad-hoc CLJS scripting on Node.js.


Experimental. Please report issues here.

Goals and features

Nbb's main goal is to make it easy to get started with ad hoc CLJS scripting on Node.js.

Additional goals and features are:

  • Fast startup without relying on a custom version of Node.js.
  • Small artifact (current size is around 1.2MB).
  • First class macros.
  • Support building small TUI apps using Reagent.
  • Complement babashka with libraries from the Node.js ecosystem.


Nbb requires Node.js v12 or newer.

How does this tool work?

CLJS code is evaluated through SCI, the same interpreter that powers babashka. Because SCI works with advanced compilation, the bundle size, especially when combined with other dependencies, is smaller than what you get with self-hosted CLJS. That makes startup faster. The trade-off is that execution is less performant and that only a subset of CLJS is available (e.g. no deftype, yet).


Install nbb from NPM:

$ npm install nbb -g

Omit -g for a local install.

Try out an expression:

$ nbb -e '(+ 1 2 3)'

And then install some other NPM libraries to use in the script. E.g.:

$ npm install csv-parse shelljs zx

Create a script which uses the NPM libraries:

(ns script
  (:require ["csv-parse/lib/sync$default" :as csv-parse]
            ["fs" :as fs]
            ["path" :as path]
            ["shelljs$default" :as sh]
            ["term-size$default" :as term-size]
            ["zx$default" :as zx]
            ["zx$fs" :as zxfs]
            [nbb.core :refer [*file*]]))

(prn (path/resolve "."))

(prn (term-size))

(println (count (str (fs/readFileSync *file*))))

(prn (sh/ls "."))

(prn (csv-parse "foo,bar"))

(prn (zxfs/existsSync *file*))

(zx/$ #js ["ls"])

Call the script:

$ nbb script.cljs
#js {:columns 216, :rows 47}
#js ["node_modules" "package-lock.json" "package.json" "script.cljs"]
#js [#js ["foo" "bar"]]
$ ls


Nbb has first class support for macros: you can define them right inside your .cljs file, like you are used to from JVM Clojure. Consider the plet macro to make working with promises more palatable:

(defmacro plet
  [bindings & body]
  (let [binding-pairs (reverse (partition 2 bindings))
        body (cons 'do body)]
    (reduce (fn [body [sym expr]]
              (let [expr (list '.resolve 'js/Promise expr)]
                (list '.then expr (list 'clojure.core/fn (vector sym)

Using this macro we can look async code more like sync code. Consider this puppeteer example:

(-> (.launch puppeteer)
      (.then (fn [browser]
               (-> (.newPage browser)
                   (.then (fn [page]
                            (-> (.goto page "https://clojure.org")
                                (.then #(.screenshot page #js{:path "screenshot.png"}))
                                (.catch #(js/console.log %))
                                (.then #(.close browser)))))))))

Using plet this becomes:

(plet [browser (.launch puppeteer)
       page (.newPage browser)
       _ (.goto page "https://clojure.org")
       _ (-> (.screenshot page #js{:path "screenshot.png"})
             (.catch #(js/console.log %)))]
      (.close browser))

See the puppeteer example for the full code.

Since v0.0.36, nbb includes promesa which is a library to deal with promises. The above plet macro is similar to promesa.core/let.

Startup time

$ time nbb -e '(+ 1 2 3)'
nbb -e '(+ 1 2 3)'   0.17s  user 0.02s system 109% cpu 0.168 total

The baseline startup time for a script is about 170ms seconds on my laptop. When invoked via npx this adds another 300ms or so, so for faster startup, either use a globally installed nbb or use $(npm bin)/nbb script.cljs to bypass npx.


NPM dependencies

Nbb does not depend on any NPM dependencies. All NPM libraries loaded by a script are resolved relative to that script. When using the Reagent module, React is resolved in the same way as any other NPM library.


To load .cljs files from local paths or dependencies, you can use the --classpath argument. The current dir is added to the classpath automatically. So if there is a file foo/bar.cljs relative to your current dir, then you can load it via (:require [foo.bar :as fb]). Note that nbb uses the same naming conventions for namespaces and directories as other Clojure tools: foo-bar in the namespace name becomes foo_bar in the directory name.

To load dependencies from the Clojure ecosystem, you can use the Clojure CLI or babashka to download them and produce a classpath:

$ classpath="$(clojure -A:nbb -Spath -Sdeps '{:aliases {:nbb {:replace-deps {com.github.seancorfield/honeysql {:git/tag "v2.0.0-rc5" :git/sha "01c3a55"}}}}}')"

and then feed it to the --classpath argument:

$ nbb --classpath "$classpath" -e "(require '[honey.sql :as sql]) (sql/format {:select :foo :from :bar :where [:= :baz 2]})"
["SELECT foo FROM bar WHERE baz = ?" 2]

Currently nbb only reads from directories, not jar files, so you are encouraged to use git libs. Support for .jar files will be added later.

Current file

The name of the file that is currently being executed is available via nbb.core/*file* or on the metadata of vars:

(ns foo
  (:require [nbb.core :refer [*file*]]))

(prn *file*) ;; "/private/tmp/foo.cljs"

(defn f [])
(prn (:file (meta #'f))) ;; "/private/tmp/foo.cljs"


Nbb includes reagent.core which will be lazily loaded when required. You can use this together with ink to create a TUI application:

$ npm install ink


(ns ink-demo
  (:require ["ink" :refer [render Text]]
            [reagent.core :as r]))

(defonce state (r/atom 0))

(doseq [n (range 1 11)]
  (js/setTimeout #(swap! state inc) (* n 500)))

(defn hello []
  [:> Text {:color "green"} "Hello, world! " @state])

(render (r/as-element [hello]))


Working with callbacks and promises can become tedious. Since nbb v0.0.36 the promesa.core namespace is included with the let and do! macros. An example:

(ns prom
  (:require [promesa.core :as p]))

(defn sleep [ms]
   (fn [resolve _]
     (js/setTimeout resolve ms))))

(defn do-stuff
   (println "Doing stuff which takes a while")
   (sleep 1000)

(p/let [a (do-stuff)
        b (inc a)
        c (do-stuff)
        d (+ b c)]
  (prn d))
$ nbb prom.cljs
Doing stuff which takes a while
Doing stuff which takes a while

Also see API docs.


Since nbb v0.0.75 applied-science/js-interop is available:

(ns example
  (:require [applied-science.js-interop :as j]))

(def o (j/lit {:a 1 :b 2 :c {:d 1}}))

(prn (j/select-keys o [:a :b])) ;; #js {:a 1, :b 2}
(prn (j/get-in o [:c :d])) ;; 1

Most of this library is supported in nbb, except the following:

  • destructuring using :syms
  • property access using .-x notation. In nbb, you must use keywords.

See the example of what is currently supported.


See the examples directory for small examples.

Next js Tutorial For Beginners

Next js Tutorial For Beginners is the today’s topic. It is no secret that creating single-page applications can be immensely challenging these days. But with the help of some libraries, frameworks, and tools, it is effortless nowadays. React.js is the common frontend libraries among the Front-end developers. Its virtual dom theory makes React faster and gives us the better application performance. Now, one problem is that Single Page Applications are not at all SEO  friendly because it is rendered on the Client side  and not Server side . So when the Search Engine crawlers try to send a request, they cannot get our meta content or description and not even the main content. Search Engines do not care about how your app is architected or whatever ideology was used to adjust and fetch the right material. Their bots are not as smart as using your apps as a real user would. All they care about is that once they send their spiders to crawl and index your site, whatever the server provides on the first request is what gets indexed. In our case, all they get is our div tag with an id and bundled JS file, and we can not index our website correctly. So some how, we need a SSR to tackle this problem and in React js, Next.js is the perfect solution.
