​
Introduction

Adonis is a fully featured web framework for Node.js. In this article, we are going to deploy a freshly created AdonisJS application to Valyent.

​
Prerequisites

  • a UNIX-like system (see WSL if you are using Windows), in order to use the Valyent CLI
  • a Valyent account, with a registered payment method (you can sign up here)
  • NodeJS and NPM installed on your machine

​
Installing the CLI

curl -L https://cli.valyent.cloud | sh
You can inspect the installation script here and the GitHub repository.

​
Authenticating

valyent auth login

​
Initializing the project

In the first place, we are going to set up a new AdonisJS project. You can refer to the official documentation. 
npm init adonis-ts-app@latest <some_project_name> && cd <some_project_name>
You can select the project structure you want. For this guide, we are going to select the web project structure. Now, we can initialize the valyent.toml configuration file, that allows to link the local codebase, to a Valyent application : 
valyent init
This command will ask you to select/create a project and an associated application.

​
Adding the Dockerfile

Let’s add a Dockerfile so that Valyent can build a Docker image for your application. 
touch Dockerfile
We can fill it with the following Dockerfile (coming from this cookbook) : 
FROM node:20.12.2-alpine3.18 AS base

# All deps stage
FROM base AS deps
WORKDIR /app
ADD package.json package-lock.json ./
RUN npm ci

# Production only deps stage
FROM base AS production-deps
WORKDIR /app
ADD package.json package-lock.json ./
RUN npm ci --omit=dev

# Build stage
FROM base AS build
WORKDIR /app
COPY --from=deps /app/node_modules /app/node_modules
ADD . .
RUN node ace build

# Production stage
FROM base
ENV NODE_ENV=production
WORKDIR /app
COPY --from=production-deps /app/node_modules /app/node_modules
COPY --from=build /app/build /app
EXPOSE 8080
CMD ["node", "./bin/server.js"]

​
Setting environment variables

​
Option 1

We can set environment variables using the valyent env set command : 
valyent env set PORT=3333 HOST=0.0.0.0 NODE_ENV=development APP_KEY=<my_app_key> DRIVE_DISK=local SESSION_DRIVER=cookie CACHE_VIEWS=true

​
Option 2

We are also able to load environment variables from a .env file : 
touch .env.prod

# .env.prod
PORT=3333
HOST=0.0.0.0
NODE_ENV=development
APP_KEY=<my_app_key>
DRIVE_DISK=local
SESSION_DRIVER=cookie
CACHE_VIEWS=true

valyent env load .env.prod
Don’t forget to add the .env.prod file to your .gitignore file.

​
Deploy the project

To expose the application’s port, we need to set up a gateway (in this case, the port 3333): 
valyent gateways create
Then, we can deploy the application : 
valyent deploy
And then, you can do: 
valyent open
to see your Adonis application in your browser.
