RIP Discord

RIP Frontend

This is the front-end repo for RipProtocol that allows users to be part of the future of Meta Greece.

We are moving at web3 speed and we are looking for talented contributors to boost this rocket. Take a look at our CONTRIBUTING GUIDE if you are considering joining a world class DAO.

🔧 Setting up Local Development

Required:

# $ git clone https://github.com/R-ripDao/Frontend.git
# $ cd rip-frontend

# set up your environment variables
# read the comments in the .env files for what is required/optional
$ cp .env.example .env

# fill in your own values in .env, then =>
$ yarn
$ yarn start

# Set up Husky (for pre-commit hooks) by running:
$ yarn prepare

The site is now running at http://localhost:3000! Open the source code and start editing!

Testing

We use the React Jest test driver for unit tests, snapshot tests and e2e tests.

To run tests in interactive mode during development:

yarn test

Unit Testing

Unit test files are co-located with the source code files that they test and follow the naming convention *.unit.test.ts. For example unit tests for OriginalSourceFile.ts are located in OriginalSourceFile.unit.test.ts. Valid extensions for test files are .js (JavaScript), .ts (TypeScript), .jsx (React JSX), .tsx (React TSX).

To run all unit test and see a coverage report:

yarn test:unit

Note that the focus of unit testing is to exercise all paths through the code hosted in this repo and only code hosted in this repo. To the extent possible, unit tests should abstract out dependencies such as remote API calls as well as crypto wallet APIs via mock functions.

Coverage thresholds are enforced via CI checks. If a new PR introduces regression in code coverage, the CI will fail. The goal is to keep us at a minimum level of test automation coverage as we introduce new code into the repo. To see the current coverage thresholds, see the coverageThreshold in package.json.

For integration testing automation that runs browser and remote API code as well as our own code, see the End-to-end (E2E) testing section below.

Mocking Remote API Calls

Unit tests should minimize dependency on remote API calls. Remote API calls slow down test execution and they also occasionally error, which may fail tests for reasons outside the app code being tested. Live API calls should be tested in End-to-end/Integration tests.

Here is an example unit test that conditionally mocks API calls.

Generative Testing

We use fast-check for generative testing which provides property-based coverage for ranges of input values. Here is an example of a unit test case in this repo that uses generative testing.

Snapshot Testing

We use Jest Snapshot tests to make sure the UI does not change unexpectedly. When you make changes to the UI (intentionally), you likely will have to update the Snapshots. You can do so by running: yarn snapshot.

Here is an example snapshot test and here is the correspoding recorded snapshot. Keep in mind that for snapshot tests to be meaningful, they have to pre-populate components with variety of data sets (realistic, edge case, invalid).

Here is a good blog post about testing React components with generative data sets.

Troubleshooting

If all tests are failing in your local environment (in particular, due to a "cannot find module" error with node_modules/babel-preset-react-app/node_modules/@babel/runtime/helpers/interopRequireDefault.js), but they should be passing (and the CI tests are passing), it's likely to be an issue with your local cache. Run the following command: yarn test --clearCache

End-to-end testing

Puppeteer (with the Dappeteer addition) is used to do browser-based end-to-end testing.

To run the tests:

  • Run the frontend, using yarn start
  • In another terminal, run the tests, using yarn test:e2e

Gitpod Continuous Dev Environment (optional)

This repo is configured to work with Gitpod.

New Contributors

If you are a new contributor, you can fork the repo and start a pre-configured gitpod environment by prefixing your fork URL with gitpod.io/#. For example:

https://gitpod.io/#https://github.com/.../...

Then follow the standard Github fork & PR workflow.

Permissioned Contributors

If you are an established contributor with access rights to create and push to branches in this repo, you can use a simpler flow.

  1. Obtain a Personal Access Token from your github UI.
  2. In your gitpod dashboard, set a new variable named GITHUB_RIP_PERSONAL_ACCESS_TOKEN to the value of the access token.
  3. Use the button below to start a pre-configured gidpod environment.

Open in Gitpod

  1. Follow the simplified Github Flow to create new branches in the repo and submit PRs.

Architecture/Layout

The app is written in React using Redux as the state container.

The files/folder structure are a WIP and may contain some unused files. The project is rapidly evolving so please update this section if you see it is inaccurate!

Theme Support

Themes are available, but it can be difficult to access the theme's colors.

Material UI components, such as Button, can use the current theme's color scheme through the color property. For example:

 <Button variant="contained" color="primary" className="cause-give-button">
  Give Yield
 </Button>

If you wish to use a theme's color scheme manually, follow these steps:

  1. Import useTheme: import { useTheme } from "@material-ui/core/styles";
  2. Instantiate the theme: const theme = useTheme();
  3. Add a style property to the component, for example:
 <Grid item className="cause-category" style={{ backgroundColor: theme.palette.background.default }}>
 {category}
 </Grid>

For the available theme properties, take a look at the themes in src/themes.

ESLint

We use ESLint to find/automatically fix problems.

  • react-app and react-hooks/recommended are important with react stuff.
  • @typescript-eslint/recommended and @typescript-eslint/eslint-recommended as recommended defaults.
  • unused-imports to automatically remove unused imports.
  • simple-import-sort to automatically sort imports alphabetically. This is opinionated, but useful because it helps avoid merge conflicts with imports (and who doesn't like neat alphabetically sorted imports anyway).
  • @typescript-eslint/explicit-function-return-type and @typescript-eslint/explicit-module-boundary-types are turned off to prioritise inferred return types over explicit return types. This is opinionated, but often times the inference Typescript makes is good enough, and sometimes help prevents type mismatches that are a pain to debug.
  • @typescript-eslint/ban-ts-comment and @typescript-eslint/ban-ts-ignore are also turned off. This could possibly be temporary, but the ability to use @ts-ignore-like directives is certainly handy as an escape hatch as we encounter errors during the migration to TS.

Reusable Components (Component Library)

Our codebase uses a custom component library extended from Material UI to make common UI patterns easy to implement on the frontend. An up-to-date list of available components, implementation examples as well as documentation is available here:

🚀 Deployment

Auto deployed on Fleek.co fronted by Cloudflare. Since it is hosted via IPFS there is no running "server" component and we don't have server sided business logic. Users are served an index.html and javascript to run our applications.

TODO: TheGraph implementation/how/why we use it.

Continuous deployment

Commits to the follow branches are automatically deployed to their respective URLs.

Branch URL
master https://app.ripdao.finance
deploy https://staging.ripdao.finance

Pull Requests: Each PR into master will get its own custom URL that is visible on the PR page. QA & validate changes on that URL before merging into the deploy branch.

Feature Flags

  • Give: by default it is enabled. It can be disabled by setting the REACT_APP_GIVE_ENABLED environment variable to "false".
