Hello, friends! 😉 I'm excited to share great news with you: the Create Go App CLI project, that I've been working on for a long time, has finally been updated to major version
☝️ You only need to focus on writing code and thinking of business-logic! The CLI will take care of the rest.
OK. Let's look at the changes together! Fasten your seat belts, we're starting.
- New in v2 and beyond
- Changes in CLI commands
- Ansible roles
- Project Wiki page
- Your assistance to the project
There are actually quite a few changes, but I've highlighted a few of the most important ones that change the way you work with the Create Go App CLI. For all other changes, please read the release notes in our GitHub repository:
This release was aimed primarily at speeding up the CLI and reducing the functionality of commands that were too overloaded.
After some analysis of the CLI command feedback, we concluded that the command to create a configuration file is very rarely used. The same comment from the focus group of our users, followed about the configuration file itself.
The most popular comment we got, was something like this:
— [...] nobody likes setting up yet another config for yet another CLI!
So, it was decided to remove
init command and file-based config
.cgapp.yml completely, even without the possibility of backward compatibility, which we successfully did in
The central CLI command has been redesigned, and its execution time has been reduced to 2-4 seconds. This was achieved by switching to generating the frontend part of the project using ready-made templates from the awesome next generation frontend tooling called Vite.js.
Now, you can choose between this frontend frameworks/libraries:
⚠️ Please note! Creating a new project is done only through the console interface (or CUI for short).
Create a new project from the custom backend and frontend templates (from your git repositories) is done by using
-t option with
||Enables to define custom backend and frontend templates.||
The structure of the created project will be as follows:
. ├── .editorconfig ├── .gitattributes ├── .gitignore ├── hosts.ini # <-- file with Ansible inventory variables ├── playbook.yml # <-- file with Ansible playbook ├── Makefile ├── backend # <-- folder with Go backend │ └── ... ├── frontend # <-- folder with JS/TS frontend (if you choose) │ └── ... └── roles # <-- folder with Ansible roles ├── backend │ └── ... ├── docker │ └── ... ├── postgres │ └── ... ├── redis │ └── ... └── traefik # or nginx (if you choose) └── ...

Also, we have seriously reworked the principle of deploying the project on a remote server. The only option left for the
deploy command is the default password call for the sudo user:

Starting with version
v2.0.0 we will actively add new Ansible roles to make the process of deploying your project to remote servers as comfortable and fast as possible.
So, now all the configuration for deployment will be in the Ansible inventory
hosts.ini (in the root of the created project). For example, this is what the inventory looks like for deploying a project with the Nginx web server:

We're recommending to use Traefik Proxy as default proxy server for your projects. The main reason: this proxy provides automatic SSL certificates from Let's Encrypt with renew out of the box.
Also, Traefik was built on the Docker ecosystem and has a really useful Web UI:
List of roles:
traefik— configured Traefik container with a simple ACME challenge via CA server.
traefik-acme-dns— configured Traefik container with a complex ACME challenge via DNS provider.
nginx— pure Nginx container with "the best practice" configuration.
List of roles:
postgres— configured PostgreSQL container with apply migrations (by golang-migrate/migrate tool) for backend.
List of roles:
redis— configured Redis container to store the backend cache.
Soon, we plan to move completely to the GitHub Wiki and do away with the separate documentation on our website for the project.
— Everything should be in one place, — as focus group users correctly noted.
