Vegan Hacktivists

Our official website. On here you can find information about the different projects Vegan Hacktivists has been working on throughout the last couple of years. You can also find out what services we provide, who we are, who we partner with and read our blog.

Introduction

Team Avocado is focused on JavaScript and responsible for our organization’s website https://veganhacktivists.org/

We're using Next.js and Tailwind for that. In this trello board you can find more stuff in the info column, for example, some of the images to be used, fonts, colors... On the board you can also access the Things to do cards. If you are doubting which card to pick first, talk to Tobias [Team Lead] 🇩🇪 and we'll take a look at the available ones or even create others, in order for you to get used to the project.

Because this team is so new we still have to document all of this somewhere, so reach out to the #🥑vegan-hacktivists channel on Discord if you need anything or something is missing! 💚

Vegan Hacktivists

Getting Started

Setting up env vars

There's a sample .env.example file with the values that need to be defined and some sensible defaults.

cp .env.example .env # .env.local works too!

To get the basic functionality to work you'll need at least:

CF_SPACE_ID
CF_DELIVERY_ACCESS_TOKEN

Ask your team lead for any key you might need!

Setting up the database

A docker-compose.yml file is included in the project. It requires a the database environment variables to be set up (see Setting up env vars).

docker compose up -d db

This command will create a database container listening on the port 5432 of your machine. To stop it, run:

docker compose down

Setting up the SMTP-Server

Running the smtp server is only necessary if you wish to login which can be useful for accessing admin functionality (see Gain access to admin pages). The docker-compose.yml inclues a smtp service, which is providing a simple smtp server without authentification accessible under port 2525.

docker compose up -d smtp

Installing the dependencies

We use pnpm as a package manager. Install it whatever way fits you best https://pnpm.io/installation. Note that you need at least version >=7.0.0.

Install the dependencies:

pnpm install

Run the development server:

pnpm dev

Open http://localhost:3000 with your browser to see the result.

Migrate and seed the database

Your database will be empty by default. We use prisma as an ORM.

Prisma will be installed along with the other dependencies if you followed the steps in Installing the dependencies.

There are three key concepts at play here: generate, migrate and seed.

Running pnpm prisma generate will create the client that connects to the database, as well as the types to access them safely from the code. For example, given a User model, it will allow this:
```
import type { User } from '@prisma/client';
import prisma from 'lib/db/prisma';
const users = prisma.findMany(); // users is of User[] type!
```
pnpm prisma migrate dev will apply all pending migrations to the database. If there are changes to the schema, it will also create a migration with those new changes. In production, migrations are applied during the build phase of the project. If you want to prototype database schemas it is recommended to use pnpm prisma db push instead, as it will avoid creating unnecessary migrations.
pnpm prisma db seed will run the prisma/seed.ts script. It's purpose is to populate the database with sample data to improve the development experience.

Gain access to admin pages

To gain access to restricted pages you first need a working smtp-setup. To setup a local running smtp server see: Setting up the SMTP-Server

Make sure that the email server settings are properly set in your .env file since our authentication is working with magic links.

Start your development server and navigate to http://localhost:3000/auth/signin and fill in a valid e-mail address. You'll receive a confirmation link you'll have to click.

Afterwards you need to use a database tool of your choice to connect to the postgresql database. You can also use pnpm prisma studio to access the database.

Looking at the users table you should see your email address under the last create users. Now change the field Role from User to Admin. After changing your role you need to log-out and log-in again to renew your permissions.

Coding conventions and guidelines

We are still figuring this out as we go, but for now we follow these guidelines for TypeScript and these conventions for React.

As for Git conventions, we try to follow the style guide as described here.

Commenting code

What to comment?

With typescript, commenting is quite different compared to javascript because data types are documented with the language already. So when writing code, we should focus on explaining decisions and motivations, rather than how or when to use this code block.
Often there are multiple ways to code something, the decision should be explained above the implementation.
Avoid unnecessary or redundant comments, such as those that simply restate the code.

Code blocks e.g. functions, including react components, and classes
- Explain the motivation for this code block and if available, reference the corresponding Trello card.
- If there are similar code blocks, write a short explanation what differentiates them and the necessity for the similar block.
Inside these code blocks
- Too complex or not easily understood code should not be written. If it is, explain why, and what this code should do.

Format

Use TSDoc as commenting style.

Examples

/**
 * Because it is required in HTML email bodies, <br/> tags are used instead of line separators.
 */
export const createFormattedHTMLMessage: (
  data: Record<string, string>,
) => string = (data) => {
  return Object.entries(data)
    .map(([field, value]) => {
      field = firstLetterUppercase(field);
      return `<b>${
        field.match(/[A-Z][a-z]+|[0-9]+/g)?.join(' ') ?? field
      }:</b> ${String(value).trim().split('\n').join('<br/>')}`;
    })
    .join('<br/>');
};

/**
 * What differentiates this from a useEffect call with empty dependencies is the option to enable/disable.
 */
const useOnce = (callback: () => void, options: UseOnceOptions = {}) => {
  const { enabled = true } = options;
  const isFirstRenderRef = useRef(true);

  useEffect(() => {
    if (!enabled || !isFirstRenderRef.current) return;

    isFirstRenderRef.current = false;
    callback();
  }, [callback, enabled]);

  return !isFirstRenderRef.current;
};

Configuring your editor

It is recommended to install EditorConfig, Prettier and ESLint, although the commit hooks will already take care of the formatting.

It is also recommended to activate the Editor: Format on save option.

Localization

Localization is implemented with react-intl

How to use translations

FormattedMessage

<FormattedMessage id="page.example.headline" defaultMessage="Example" />

useIntl

const intl = useIntl();
intl.formatMessage({ id: 'page.example.headline', defaultMessage: 'Example' });

Ids

Ids are created from context kinds and names, starting with the root element of the component and ending with the translation target. Segments are concatenated with dots. Ids must be lowercase and written in kebab style. This is to avoid duplicate IDs and provide some context to translators.

example for a headline on the index page:

page.index.section.projects.headline

Scripts

pnpm translation:compile compiles all messages into a format consumable by react-intl.
pnpm translation:extract finds new messages and extracts them into /translation/data/en.json. Runs translation:compile afterwards.
pnpm translation:update compares the defaultMessages in FormattedMessage and intl.formatMessage with previously extracted messages and updates the code where differences are found.
pnpm translation:translate next.config.ts locales will be used as language key for the deepl translation API, to generate translations of missing messages of the corresponding language. Results are written to /translation/data/{locale}.json. Runs translation:compile afterwards.

How to add new translations

Add new locales by updating the array nextConfig.i18n.locales in next.config.js.
Translations will be generated in a pipeline job or by using the above scripts.

Ignore text/variables in messages during the translation process

Wrap the part of the message in a no-localization tag:
Donate <no-localization>{currencyName}</no-localization>
The no-localization tag will exclude it from translation and keep the variable name.

Weblate

Weblate is used to manage translations.
Our instance is running at localize.veganhacktivists.org
The configured file format is WebExtension JSON.

The FormatJs format supported with Weblate 5.4 is currently unusable as the dots in the translation ids are interpreted as accessor for nested values in objects. E.g. "page.support.title": { "defaultMessage": "abc" } is read correctly, but written as "page": { "support": { "title": { "defaultMessage": "abc" } } } by weblate.

Add a new language

Add the locale code to the nextConfig.i18n.locales array in next.config.js
Run pnpm translation:translate to generate a file for the new locale with translated messages using deepl.com. // API_KEY must be configured
Weblate will pick up the new locale

How weblate is integrated

Weblate reads and updates the translation files in this repository (translation/data/*.json).
Weblate is pulling and pushing using ssh to this repository.
Weblate is notified of new changes via a github webhook.
Translations should only be changed in weblate.
Weblate pushes updated translations to the weblate/translations branch, when changes are committed. This branch must be manually merged to main.

Translation workflow

Creation

Translations are created using react-intl with intl.formatMessage(...) or <FormattedMessage ... />. Run pnpm translation:extract to sync code changes to the translation files. When committed and pushed to the main branch, new translations are registered and made available by weblate.

Update

Translations are modified in the weblate ui. Before the updated text can be published to veganhacktivists.org, it must be committed in weblate and pushed to the weblate/translations branch. This branch must be manually merged to main using a pull request.

Deletion

Removing a translation from the code and running pnpm translation:extract will also delete it from the translation files, which forces weblate to forget this translation too.

Grab a card

Steps for working on a card from our Trello board:

Grab a card from the Things to do column and drag it to the In Progress column
Create a new branch feature/my-new-feature off the main branch
Create a Pull Request when you're done
Move the card to PR Ready
Sit back and wait for approvals or comments!

Feel free to ask other team members to review Pull Requests.

Frequently Asked Questions

How should URLs be formatted?
URLs should use dashes (-) instead of underscores (_), so /this-is/my/page should be used instead of /this_is/my/page.
