How to Automate Nuxt.js Deployments With Heroku and CircleCI

Manually deploying a Nuxt project is pretty easy when teams are small. However, as projects and teams grow, they usually turn to continuous integration and deployment (CI/CD) in their DevOps to automate their testing and deployment. This is when deployments — and the setup of deployments — can get complicated.

In this article, we’ll look at how to easily set up an automated CI/CD system for a Nuxt project using Heroku and CircleCI. We’ll walk through all the details, from setting up your GitHub repository to automating your tests to pushing your code changes. Then we’ll look at some suggested next steps.


What Is Nuxt.js?

First, here’s a little background on Nuxt and why developers might choose it as part of their stack.

When Vue was first released, developers fell in love. With its simple template syntax and component structure, Vue makes it easy to spin up beautiful single-page applications (SPAs) with ease.

However, developers soon realized SEO was a problem. Since SPAs are deployed as a shell and the content isn’t inserted until runtime, developers learned it could be difficult for search engines to accurately index the contents. Because of this, developers needed a solution for handling server-side rendering (SSR) of their Vue applications.

Enter Nuxt.

Nuxt is an open-source framework that combines all of the oft-used Vue libraries, bundling in Vue RouterVuex, and Vue server-side rendering (SSR), to provide Vue.js developers with the architecture for a smoother development experience. With Nuxt, developers can get an SEO-friendly Vue application (with SSR) up and running within minutes.


Our Sample Project

Now let’s look at our sample project and deployment setup. For this project, we’ll be using GitHub as our repository, Heroku as our host, and CircleCI as our CI/CD tool.

Heroku is a PaaS solution that makes it easy to deploy and manage apps. CircleCI provides cloud-based CI/CD, running automated jobs in containers as soon as the project code is pushed to GitHub. These jobs perform tests, send success or failure notifications, and then deploy built applications to cloud-service environments.

In the end, we want our outcome to be: When we push our master branch to GitHub, an automated process will run all of our tests and then (if all the tests pass) deploy the application to Heroku.

To that end, I’ll take you through the following steps:

1\. Set up a GitHub repository
2\. Create a basic Nuxt application
3\. Create the tests for our Nuxt application
4\. Manually deploy the Nuxt application to Heroku
5\. Set up automated testing with CircleCI
6\. Set up atuomated deployment to Heroku

Sound pretty simple? It will be. Let’s go!


1. Set Up a GitHub Repository

This tutorial requires an account with GitHub. A basic GitHub Free account will be sufficient.

We’ll set up a GitHub repository to house our project code. Later, we’ll connect our GitHub account with our CircleCI account. Whenever we push code to GitHub, this action will trigger a webhook to notify CircleCI to begin the CI/CD automation process.

On the “Your Repositories” page in GitHub, click on the “New” repository button.

Choose any name you’d like for this private repository. For this tutorial, we’ll call our repository my-heroku-nuxt-app.

Image for post

Click on “Create repository” to finish up. Then, clone the repository onto your local machine. In the command below, make sure to use your own GitHub username. Notice we’re cloning the empty repository into a folder called app.

~/$ git clone git@github.com:[GITHUB USERNAME]/my-heroku-nuxt-app.git app 
Cloning into 'my-heroku-nuxt-app'... 
warning: You appear to have cloned an empty repository.

Excellent. Now that we have our app folder, let’s fill it up with a shiny, new Nuxt application.

NBB: Ad-hoc CLJS Scripting on Node.js

Nbb

Not babashka. Node.js babashka!?

Ad-hoc CLJS scripting on Node.js.

Status

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.

Requirements

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).

Usage

Install nbb from NPM:

$ npm install nbb -g

Omit -g for a local install.

Try out an expression:

$ nbb -e '(+ 1 2 3)'
6

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
"/private/tmp/test-script"
#js {:columns 216, :rows 47}
510
#js ["node_modules" "package-lock.json" "package.json" "script.cljs"]
#js [#js ["foo" "bar"]]
true
$ ls
node_modules
package-lock.json
package.json
script.cljs

Macros

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)
                                        body))))
            body
            binding-pairs)))

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)'
6
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.

Dependencies

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.

Classpath

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"

Reagent

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

ink-demo.cljs:

(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]))

Promesa

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]
  (js/Promise.
   (fn [resolve _]
     (js/setTimeout resolve ms))))

(defn do-stuff
  []
  (p/do!
   (println "Doing stuff which takes a while")
   (sleep 1000)
   1))

(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
3

Also see API docs.

Js-interop

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.

Examples

See the examples directory for small examples.
