Static JavaScript service
How to define a new static JavaScript service or convert an existing Docker service to use a static JavaScript build deployed to a CDN
Creating a static JavaScript service in Release requires the following parameters:
static
:true
for a static build,false
to switch back to a Docker build.build_base
: the path to the JavaScript project in your repository.build_command
: your JavaScript build command.build_output_directory
: the directory the build command outputs the build to.
Here's an example static build:
services:
- name: frontend
static: true
build_command: GENERATE_SOURCEMAP=false yarn build
build_base: frontend
build_output_directory: build/
Release allows you to define a service with both static JavaScript and Docker service parameters. You can also easily convert any single page JavaScript Docker service to a static JavaScript build.
Here is a Docker-based JavaScript frontend that was generated from a
docker-compose
by Release:services:
- name: frontend
image: acme-co/awesome-project/frontend
ports:
- type: node_port
target_port: '3000'
port: '3000'
has_repo: true
memory:
limits: 4Gi
requests: 100Mi
You can update this to use static builds by adding the same parameters for defining a static JavaScript service as outlined above. Use the
static
parameter to switch the service between a static JavaScript build and running in a Docker container.services:
- name: frontend
image: acme-co/awesome-project/frontend
ports:
- type: node_port
target_port: '3000'
port: '3000'
has_repo: true
memory:
limits: 4Gi
requests: 100Mi
static: true
build_command: yarn build
build_base: frontend
build_output_directory: build/
During builds, you can control the version of NodeJS that is used by supplying the version information in a
.nvmrc
file. We recommend setting the file at the root of your project, but you can also create the file at the subtree where your project lives. You can read the documentation to find more details. This is a simple example that will use the version that you specify from your local version:cd /project/root
node -v > .nvmrc
git add .nvmrc
git commit -m "Set javascript version"
git push

If you want the benefits of a static CDN site but don’t want your site to be public, Release has a simple way to add basic authentication to your static content via our proprietary Edge Routing System.
Static site basic authentication does not allow for multiple users with their own passwords. It is only suitable for a single shared user and password scheme. It is not suitable for production environments.
Basic authentication does not use encryption to secure usernames and/or passwords. It is not suitable for applications running in production.
If you would like to add basic authentication to your site, set up a static application as shown in the previous section. Then, find the
hostnames
entry for your static application as shown in this example:hostnames:
- api-${env_id}-${domain}
- web-client-${env_id}-${domain}
Replace the
web-client-...
line with the following example:hostnames:
- api-${env_id}-${domain}
routes:
- name: web-client
hostname: web-client-${env_id}-${domain}
auth:
username: admin
password: letmein
rules:
- service: web-client
path: "/"
