Ω Olympus Frontend

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

_ Note We're currently in the process of switching to TypeScript. Please read this guide on how to use TypeScript for this repository. https://github.com/OlympusDAO/olympus-frontend/wiki/TypeScript-Refactor-General-Guidelines _

🔧 Setting up Local Development

Required:

• Node v14
• Yarn
• Git

$ git clone https://github.com/OlympusDAO/olympusdao.git
$ cd olympusdao

# 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

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

If you would like to run the frontend in a Docker image (e.g. to isolate dependencies and the nodejs version), run yarn docker-start.

Rinkeby Testing

Rinkeby faucet for sOHM: Lives here, to retrieve test sOHM click Connect to Web3 and use function #3: dripSOHM. After connecting to web3, click Write to execute and 10 sOHM will automatically be transferred to your connected wallet.

Note: The faucet is limited to one transfer per wallet every 6500 blocks (~1 day)

Rinkeby faucet for WETH: Wrap rinkeby eth on rinkeby uniswap

Rinkeby faucets for LUSD, FRAX & DAI can be taken from rinkeby etherscan:

1. Go to src/helpers/AllBonds.ts
2. then copy the rinkeby reserveAddress for the applicable bond & navigate to that contract on rinkeby etherscan.
3. On Rinkeby etherscan use the mint function. You can use the number helper for 10^18 & then add four more zeros for 10,000 units of whichever reserve you are minting.

Avax Fuji Testnet

1. avax faucet
2. explorer

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!

./src/

├── abi/          // Contract ABIs from etherscan.io

├── components/   // Reusable individual components
├── constants.js/ // Mainnet Addresses & common ABI

├── helpers/      // Helper methods to use in the app

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.

Application translation

Olympus uses linguijs to manage translation.

The language files are located in a submodule deployed in src/locales/translations. This submodule points to the olympus translation repository

In order to mark text for translation you can use:

• The component in jsx templates eg. <Trans>Translate me!</Trans>
• The t function in javascript code and jsx templates. t`Translate me` You can also add comments for the translators. eg.

t({
 id: "do_bond",
 comment: "The action of bonding (verb)",
})

When new texts are created or existing texts are modified in the application please leave a message in the OlympusDao app-translation channel for the translators to translate them.

Resolving merge conflicts with translations

$ git diff
# shows two commits in conflict below (fbdd867,e6e0919)
diff --cc src/locales/translations
index fbdd867,e6e0919..0000000
--- a/src/locales/translations
+++ b/src/locales/translations

cd src/locales/translations
# first commit
git checkout fbdd867
# merge in second commit
git merge e6e0919
git commit

cd ../../..
git add src/locales/translations
git commit

🚀 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.olympusdao.finance
deploy	https://staging.olympusdao.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 disabled. It can be enabled by setting the REACT_APP_GIVE_ENABLED environment variable to "true", or appending give_enabled as a URL parameter.

👏🏽 Contributing Guidelines

We keep an updated list of bugs/feature requests in Github Issues.

Filter by "good first issue" to get your feet wet! Once you submit a PR, our CI will generate a temporary testing URL where you can validate your changes. Tag any of the gatekeepers on the review to merge them into master.

NOTE: For big changes associated with feature releases/milestones, they will be merged onto the develop branch for more thorough QA before a final merge to master

Defenders of the code:

Only the following people have merge access for the master branch.
