Vega front-end monorepo
The front-end monorepo provides a toolkit for building apps that interact with Vega, as well as the apps themselves.
This repository is managed using Nx.
🔎 Applications in this repo
Block explorer
The Vega block explorer provides an interface that allows users to search for and see transactions, blocks, parties, assets, markets and more on the Vega chain.
Trading UI
The trading interface built based on a component toolkit. It will provide a way for participants to interact with markets and provide resources for others to build additional open-source user interfaces.
Token
The utility dApp for interacting with the Vega token and using its' utility. This includes; delegation, nomination, governance and redemption of tokens.
Explorer
The block explorer for the Vega network, showing details of raw chain states and the state of markets on the Vega network.
Stats
An application for the status of the Vega network. Showing block height and other network activity.
Static
Hosting for static content being shared across apps, for example fonts.
🧱 Libraries in this repo
UI toolkit
The UI toolkit contains a set of components used to build interfaces that can interact with the Vega protocol, and follow the design style of the project.
It contains a storybook that can be served with yarn nx run ui-toolkit:storybook.
Tailwind CSS config
The Tailwind CSS config contains theme that align default config with Vega design system.
Cypress
For shared Cypress logic, commands and steps.
Web3
A utility library for connecting to the Ethereum network and interacting with Vega Web3 contracts.
React Helpers
Generic react helpers that can be used across multiple applications, along with other utilities.
💻 Develop
Set up
Check you have the correct version of Node. You can install NVM to switch between node versions. Then NVM install.
Before you build you will need to yarn install in the root directory.
The repository includes a number of template .env files for different networks. Copy from these to the .env file before serve to launch app with different network. You can serve any application with yarn nx run <name-of-app>:serve.
Build
Run nx build my-app to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.
Run nx serve my-app for a dev server. Navigate to the port specified in app/<project-name>/project.json. The app will automatically reload if you change any of the source files.
Using Apollo GraphQL and Generate Types
In order to generate the schemas for your GraphQL queries, you can run nx run types:generate.
If it is the first time you are running the command, make sure you are setting up the environment variable from apollo.config.js.
export NX_VEGA_URL=https://lb.testnet.vega.xyz/query
yarn nx run types:generate
Running tests
Run yarn nx run <my-app>-e2e:e2e to execute the e2e tests with cypress, or nx affected:e2e will execute just the end-to-end tests affected by a change. You can use the --watch flag to open the cypress tests UI in watch mode, see cypress executor for all CLI flags.
Run nx test my-app to execute the unit tests with Jest, or nx affected:test to execute just unit tests affected by a change. You can also use --watch with these test to run jest in watch mode, see Jest executor for all CLI flags.
Trading app E2E tests
To run tests locally using your own wallets you can add the following environment variables to cypress.json
- Change
TRADING_TEST_VEGA_WALLET_NAMEto your Vega wallet name - Add
TRADING_TEST_VEGA_WALLET_PASSPHRASEas your wallet passphrase - Add
ETH_WALLET_MNEMONICas your Ethereum wallet mnemonic
Formatting
In CI linting, formatting and also run. These checks can be seen in the CI workflow file.
- To fix linting errors locally run
yarn nx lint --fix - To fix formatting errors local run
yarn nx format:write - For either command you may use
--allto run across the entire repository

Docker & Vegacapsule
Docker
The Dockerfile for running the frontends is pretty basic, merely building the application with the APP arg that is passed in and serving the application from nginx. The only complexity that exists is that there is a script which allows the passing of run time environment variables to the containers. See configuration below for how to do this.
You can build any of the containers locally with the following command:
docker build . --build-arg APP=[YOUR APP] --tag=[TAG]
In order to run a container:
docker run -p 3000:80 [TAG]
Config
As environment variables are build time and not run time in frontend applications. We have built a system which allows for passing run time environment variables, this generates a JSON file that will override the default environment variables that the container was built with (which is always testnet, using the default .env files).
In order to override specific environment variables you can pass these to the container like this:
docker run -e NX_VEGA_URL=https://n04.d.vega.xyz/query -p 3000:80 [TAG]
Which will now point the app to use a devnet data node. To see a list of all possible config properties see the readme.md for each app in the app directory.
Vega capsule
Coming soon! You will be able to run the containers within Vega Capsule.
You can run against a local instance of Vega Capsule today by using the .env.capsule present in the apps.
