Development: Getting Started

Warning

Be sure to use the Nightly version of the docs to ensure you're up to date with the latest changes.

After reading through the Code Contributions Guide and forking the repo you can start working. This project is developed with docker and as such you will be greatly aided by using docker for development. It's not necessary but it is helpful.

With VSCode Dev Containers

Prerequisites

• Docker
• Visual Studio Code

First ensure that docker is running. Then when you clone the repo and open with VS Code you should see a popup asking you to reopen the project inside a development container. Click yes and it will build the development container and run the setup required to run both the backend API and the frontend webserver. This also pre-configures pre-commit hooks to ensure that the code is up to date before committing.

Checkout the makefile for all of the available commands.

Tip

For slow terminal checkout the solution in this GitHub Issue

git config oh-my-zsh.hide-info 1

Without Dev Containers

Prerequisites

• Python 3.10
• Poetry
• Node v16.x
• yarn

Installing Dependencies

Once the prerequisites are installed you can cd into the project base directory and run make setup to install the python and node dependencies.

Linux / macOS

# Naviate To The Root Directory
cd /path/to/project

# Utilize the Makefile to Install Dependencies
make setup

Windows

# Install Python Dependencies
Set-Directory -Path "C:\path\to\project"
poetry install

# Install Node Dependencies
Set-Directory frontend
yarn install

Setting ENV Variables

Before you start the server you MUST copy the template.env and frontend/template.env files to their respective locations with the name .env and frontend/.env respectively. The application will-not run without these files.

Starting The Server

Once that is complete you're ready to start the servers. You'll need two shells open, One for the server and one for the frontend.

Linux / macOS

# Terminal #1
make backend

# Terminal #2
make frontend

Windows

# Terminal # 1
poetry run python mealie/db/init_db.py # Initialize the database
poetry run python mealie/app.py # start application

# Terminal # 2
Set-Directory frontend
yarn run dev

Make File Reference

Run make help for reference. If you're on a system that doesn't support makefiles in most cases you can use the commands directly in your terminal by copy/pasting them from the Makefile.

Internationalization

Frontend

We use vue-i18n package for internationalization. Translations are stored in json format located in frontend/lang/messages.

Backend

Translations are stored in json format located in mealie/lang/messages.

Quick frontend localization with VS Code

i18n Ally for VScode is helpful for generating new strings to translate using Code Actions. It also has a nice feature, which shows translations in-place when editing code.

A few settings must be tweaked to make the most of its features. Some settings are stored on project level, but most of them have to be set manually in your workspace or user settings.\ We've found that the following settings work best:

  "i18n-ally.enabledFrameworks": ["vue"],
  "i18n-ally.extract.autoDetect": true,
  "i18n-ally.dirStructure": "auto",
  "i18n-ally.extract.targetPickingStrategy": "global-previous",
  "i18n-ally.displayLanguage": "en-US",
  "i18n-ally.keystyle": "nested",
  "i18n-ally.sourceLanguage": "en-US",
