Econia Frontend

This repository contains a reference frontend implementation for the Econia protocol. By default the candlestick chart functionality relies on the closed source TradingView Advanced Charts repository. If you do not have access to the private repository, the candlestick functionality falls back on the open source Lightweight Charts repository.

Prerequisites

1 - Ensure that you clone the Github repository with SSH

NOTE: Skip this part if you've already used SSH or want to use the open source charting library

Open Terminal and run the following commands:

git remote set-url origin git@github.com:econia-labs/econia-frontend.git

2 - Pull the TradingView submodule

NOTE: Skip this part if you do not want to show the trading chart or have no access rights to the TradingView repository

The TradingView Advanced Charts repository is the submodule of this repository which is used for displaying the trading chart of a specific market, and is initialized at src/frontend/public/static.

In essence, adding the TradingView as a submodule clones the TradingView repository and builds it into static files. Therefore, you need to have the access rights to the TradingView repository.

To get the access rights, you have to contact the TradingView team and wait for approval.

Moreover, the submodule path is set up to use SSH protocol with the github.com hostname so that you need to manage your SSH keys to make sure that you are using the correct configuration.

If you don't have any SSH keys

Follow this guide to generate one.

In order to make this repository to be able to use the TradingView, run the following commands in your terminal:

git submodule init
git submodule update

NOTE: If you don't mind using the open source charting library, you can simply run:

git clone https://github.com/econia-labs/econia-frontend.git

Installations

• Get pnpm if you don't already have it

• Navigate to the Frontend Folder

cd src/frontend

• Install dependencies

pnpm i # pnpm is required

• Copy .env.example file

cp -R .env.example .env.local

• Run the development server:

pnpm run dev

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

Deploying on Vercel

1 - Environment Preparation

To deploy on Vercel, you'll need to set up the following environment variables:

Variable	Meaning
NEXT_PUBLIC_ECONIA_ADDR	The Econia module address
NEXT_PUBLIC_FAUCET_ADDR	The Econia faucet address
NEXT_PUBLIC_NETWORK_NAME	The network name (for example, "mainnet" or "testnet")
NEXT_PUBLIC_API_URL	The Econia REST API URL
NEXT_PUBLIC_RPC_NODE_URL	Aptos RPC URL
GITHUB_ACCESS_TOKEN	Access token for the GitHub account with access to the private TradingView repo. This is required when deploying to Vercel
NEXT_PUBLIC_UNCONNECTED_NOTICE_MESSAGE	The modal message to display when a user has not connected their wallet yet
NEXT_PUBLIC_READ_ONLY	For setting read-only mode, where "1" means the user can't submit or sign transactions and "0" means they can
NEXT_PUBLIC_READ_ONLY_MESSAGE	The error message displayed to a user when they attempt to sign a transaction in read-only mode
NEXT_PUBLIC_DEFAULT_MARKET_ID	Default market id
NEXT_PUBLIC_INTEGRATOR_ADDRESS	The address that will receive integrator fees for taker orders. This address must have a fee store registered for the given market
TRY_CLONING_TRADINGVIEW	Set to any value other than "1" to skip private submodule cloning

The variables above will be added into the Vercel project, you can find them at the file .env.example or .env.local which you created from previous steps. However, the GITHUB_ACCESS_TOKEN is still missing, you have to create on your own.

2 - Generating a GITHUB_ACCESS_TOKEN

To generate a GITHUB_ACCESS_TOKEN:

1. Go to https://github.com/settings/tokens/new
2. Provide a descriptive note.
3. In Expiration selection box, choose No expiration
4. In the Select scopes section, click on repo - Full control of private repositories to select all repository-related options.
5. Click Generate token
6. Copy the generated token to your Vercel environment variables and name it GITHUB_ACCESS_TOKEN

3 - Log into the Vercel system using your Github account

Use your Github account, that has the access to this econia-frontend repository, to connect to Vercel.

Now you are navigated to your default team on Vercel and able to create a new project.

4 - Create a Vercel project

Step 1: Import project

On your screen, click Add New button and select Project to create a new project or shortly clicks Import project to import the Github repository.

The Vercel webiste displays a list of repositories existing in your Github account.

Now click the Import button on the econia-frontend repository.

Step 2: Configure your project

Once imported successfully, Vercel asks you to configure your project and deploy.

1. Project Name: The project name is automatically generated, you can change it as you want.

2. Root Directory: At the Root Directory field, click the Edit button next to it. A modal pops up and tells you to select the directory where your source code is located. Then, you must select the path econia-frontend/src/frontend and click Continue.

3. Framework Preset: As the directory at the above path is a NextJS project then Vercel automatically detects that its Framework Preset is NextJS.

4. Build and Output Settings: Override the Install Command with the following:

   npm run vercel-install

5. Environment Variables: Paste all the environment variables in .env.local file to the table. There's a trick that you don't need to copy and paste each variable at a time, just copy your .env.local file and paste into the input field.

Step 3: Deploy your project

Click the Deploy button, wait for several minutes and see the results.
