Developing

This article outlines how to get Dashy running in a development environment, and outlines the basics of the architecture. If you're adding new features, you may want to check out the Development Guides docs, for tutorials covering basic tasks.

Setting up the Dev Environment

Prerequisites

You will need either the latest or LTS version of Node.js to build and serve the application and Git to easily fetch the code, and push any changes. If you plan on running or deploying the container, you'll also need Docker. To avoid any unexpected issues, ensure you've got at least NPM V 7.5 or Yarn 1.22 (you may find NVM helpful for switching/ managing versions).

Running the Project

Get Code: git clone https://github.com/Lissy93/dashy.git
Navigate into the directory: cd dashy
Install dependencies: yarn
Start dev server: yarn dev

Dashy should now be being served on http://localhost:8080/. Hot reload is enabled, so making changes to any of the files will trigger them to be rebuilt and the page refreshed.

Project Commands

yarn dev - Starts the development server with hot reloading
yarn build - Builds the project for production, and outputs it into ./dist
yarn start - Starts a web server, and serves up the production site from ./dist
yarn validate-config - Parses and validates your conf.yml against Dashy's schema
yarn lint - Lints code to ensure it follows a consistent, neat style
yarn test - Runs tests, and outputs results

There is also:

yarn build-and-start will run yarn build and yarn start
yarn build-watch will output contents to ./dist and recompile when anything in ./src is modified, you can then use either yarn start or your own server, to have a production environment that watches for changes.

Using the Vue CLI:

The app is build with Vue, and uses the Vue-CLI Service for basic commands.
If you have NPX installed, then you can invoke the Vue CLI binary using npx vue-cli-service [command]
Vue also has a GUI environment that can be used for basic project management, and may be useful for beginners, this can be started by running npx vue ui, and opening up http://localhost:8000

Note:

If you are using NPM, replace yarn with npm run
If you are using Docker, precede each command with docker exec -it [container-id]. Container ID can be found by running docker ps

Environmental Variables

All environmental variables are optional. Currently there are not many environmental variables used, as most of the user preferences are stored under appConfig in the conf.yml file.

You can set variables either in your environment, or using the .env file.

NODE_ENV - Current environment, can be either development, production or test
PORT - The port to expose the running application on
HOST - The host that Dashy is running on, domain or IP
BASE_URL - The default base path for serving up static assets
VUE_APP_DOMAIN - Usually the same as BASE_URL, but accessible in frontend
INTEGRITY - Should enable SRI for build script and link resources
IS_DOCKER - Computed automatically on build. Indicates if running in container
VUE_APP_VERSION - Again, set automatically using package.json during build time

Environment Modes

You can set the environment using the NODE_ENV variable. By default, the correct environment should be selected based on the script you run to start the app. The following environments are supported: production, development and test. For more info, see Vue CLI Environment Modes.

Git Strategy

Git Flow

Like most Git repos, we are following the Github Flow standard.

Create a branch (or fork if you don'd have write acces)
Code some awesome stuff, then add and commit your changes
Create a Pull Request, complete the checklist and ensure the build succeeds
Follow up with any reviews on your code
Merge 🎉

Git Branch Naming

The format of your branch name should be something similar to: [TYPE]/[TICKET]_[TITLE] For example, FEATURE/420_Awesome-feature or FIX/690_login-server-error

Commit Emojis

Using a single emoji at the start of each commit message, to indicate the type task, makes the commit ledger easier to understand, plus it looks cool.

PR Guidelines

Once you've made your changes, and pushed them to your fork or branch, you're ready to open a pull request!

For a pull request to be merged, it must:

Must be backwards compatible
The build, lint and tests (run by GH actions) must pass
There must not be any merge conflicts

When you submit your PR, include the required info, by filling out the PR template. Including:

A brief description of your changes
The issue, ticket or discussion number (if applicable)
For UI relate updates include a screenshot
If any dependencies were added, explain why it was needed, state the cost associated, and confirm it does not introduce any security issues
Finally, check the checkboxes, to confirm that the standards are met, and hit submit!

Resources for Beginners

New to Web Development? Glad you're here! Dashy is a pretty simple app, so it should make a good candidate for your first PR. Presuming that you already have a basic knowledge of JavaScript, the following articles should point you in the right direction for getting up to speed with the technologies used in this project:

As well as Node, Git and Docker- you'll also need an IDE (e.g. VS Code or Vim) and a terminal (Windows users may find WSL more convenient).

App Info

Style Guide

Linting is done using ESLint, and using the Vue.js Styleguide, which is very similar to the AirBnB Stylguide. You can run yarn lint to report and fix issues. While the dev server is running, issues will be reported to the console automatically, and any lint errors will trigger the build to fail. Note that all lint checks must pass before any PR can be merged. Linting is also run as a git pre-commit hook

The most significant things to note are:

Indentation should be done with two spaces
Strings should use single quotes
All statements must end in a semi-colon
The final element in all objects must be preceded with a comma
Maximum line length is 100
There must be exactly one blank line between sections, before function names, and at the end of the file
With conditionals, put else on the same line as your if block’s closing brace
All multiline blocks must use braces
Avoid console statements in the frontend

JavaScript: github.com/airbnb/javascript

Development Tools

Performance - Lighthouse

The easiest method of checking performance is to use Chromium's build in auditing tool, Lighthouse. To run the test, open Developer Tools (usually F12) --> Lighthouse and click on the 'Generate Report' button at the bottom.

Dependencies - BundlePhobia

BundlePhobia is a really useful app that lets you analyze the cost of adding any particular dependency to an application

Release Schedule

We're using Semantic Versioning, to indicate major, minor and patch versions. You can find the current version number in the readme, and check your apps version under the config menu. The version number is pulled from the package.json file. Typically there is a new major release every 2 weeks, usually on Sunday, and you can view these under the Releases Page. Each release will create a new tag on GitHub, and each major release will also result in the creation of a new tag on DockerHub, so that you can fix your container to a certain version. For a full breakdown of each change, you can view the Changelog. Each new feature or significant change needs to be submitted through a pull request, which makes it easy to review and track these changes, and roll back if needed.

Automated Workflows

Dashy makes heavy use of GitHub Actions to fully automate the checking, testing, building, deploying of the project, as well as administration tasks like management of issues, tags, releases and documentation. The following section outlines each workflow, along with a link the the action file, current status and short description. A lot of these automations were made possible using community actions contributed to GH marketplace by some amazing people.

Code Processing

Action	Description
Code Linter	After a pull request is created, all new code changes will be linted, and the CI will fail with a helpful message if the code has any formatting inconsistencies
Code Spell Check	After a PR submitted, all auto-fixable spelling errors will be detected, then Liss-Bot will create a separate PR to propose the fixes
Dependency Update Summary	After a PR is submitted, if any of the dependencies are modified, then Liss-Bot will add a comment, explaining which packages have been added, removed, updated or downgraded, as well as other helpful info
Get Size	Adds comment to PR if the size of the built + bundled application has changed compared to the previous version
Security Scan	Uses Snyk to scan the code and dependencies after a PR. Will add a comment and cause the build to fail if a new vulnerability or potential issue is present

Releases

Action	Description
Create Tag	Whenever the version indicated in package.json is updates, a new GitHub tag will be created for that point in time
Build App	After changes are merged into the master branch, the app will be build, with output pushed to the `dev-demo` branch
Cache Artifacts	After build, returned files will be cached for future actions for that commit
Docker Publish	After PR is merged, the multi-architecture Docker container will be built, and then published to GHCR

Issue Management

Action	Description
Close Incomplete Issues	Issues which do not match any of the issue templates will be closed, and a comment posted explaining why
Close Stale Issues	Issues which have not been updated for 6 weeks will have a comment posted to them. If the author does not reply within the next week, then the issue will be marked as stale and closed. The original author may still reopen the issue at any time
Close Potential Spam Issues	Auto-closes issues, and adds a comment if it was submitted by a user who hasn't yet interacted with the repo, is new to GitHub and has not starred the repository. The comment will advise them to check their issue is complete, and then allow them to reopen it
Issue Translator	Auto-translates any comments and issues that were written in any language other than English, and posts the translation as a comment below
Label Sponsors	Adds a special label to any issues or pull requests raised by users who are sponsoring the project via GitHub, so that they can get priority support
LGTM Comment	When a PR review contains the words LGTM (looks good to me), the Liss-Bot will reply with a random celebratory or thumbs up GIF, just as a bit of fun
Mind your Language	Replies to any comment (on issue or PR) that contains profanities, offensive or inappropriate language with a polite note reminding the user of the code of conduct
Release Notifier	Once a release has been published which fixes an issue, a comment will be added to the relevant issues informing the user who raised it that it was fixed in the current release
Update Issue after Merge	After a PR which fixes an issue is merged, Liss-Bot will add a comment to said issue based on the git commit message
Auto Add Comment Based on Tag	Will add comment with useful info to certain issues, based on the tag applied

PR Management

Action	Description
PR Commenter	Adds comment with helpful info to pull requests, based on which files have been changes
Issue from Todo Code	When a `todo` note is found in the code after a PR, then Liss-Bot will automatically raise an issue, so that the todo can be addressed/ implemented. The issue will be closed once the todo has been implemented or removed

Documentation & Reports

Action	Description
Generate Credits	Generates a report, including contributors, collaborators, sponsors, bots and helpful users. Will then insert a markdown table with thanks to these GitHub users and links to their profiles into the Credits page, as well as a summary of sponsors and top contributors into the main readme
Generate Issue Summary	Creates a markdown report of opened and closed linked-issues, sorted by category
Wiki Sync	Generates and publishes the repositories wiki page using the markdown files within the docs directory

Notes

Known Warnings

When running the build command, several warnings appear. These are not errors, and do not affect the security or performance of the application. They will be addressed in a future update

WARN A new version of sass-loader is available. Please upgrade for best experience. - Currently we're using an older version of SASS loader, since the more recent releases do not seem to be compatible with the Vue CLI's webpack configuration.

WARN asset size limit: The following asset(s) exceed the recommended size limit (244 KiB). - For the PWA to support Windows 10, a splash screen asset is required, and is quite large. This throws a warning, however PWA assets are not loaded until needed, so shouldn't have any impact on application performance. A similar warning is thrown for the Raleway font, and that is looking to be addressed.
