--- title: Yarn Setup sidebar_position: 1 description: | Set up the project with Yarn sidebar_custom_props: icon: TbScript --- import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem'; In this document, you'll learn how to install the project using yarn. You should use this method since it's the easiest way to get started but you can also run the project with [Docker](/contributor/local-setup/docker-setup). :::info `npm` does not support local packages well, opt for `yarn` instead. ::: ## Prerequisites Before you can install and use Twenty, make sure you install the following on your computer: - [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) - [Node v18](https://nodejs.org/en/download) - [yarn v4](https://yarnpkg.com/getting-started/install) - [nvm](https://github.com/nvm-sh/nvm/blob/master/README.md) :::info Note Yarn is now shipped with Node.js nowadays, so you don't need to install it separately. You should only have to run `corepack enable` to enable Yarn if you haven't done it yet. ::: 1. Install WSL Open PowerShell as Administrator and run: ```powershell wsl --install ``` You should now see a prompt to restart your computer. If not, restart it manually. Upon restart, a powershell window will open and install Ubuntu. This may take up some time. You'll see a prompt to create a username and password for your Ubuntu installation. 2. Install and configure git ```bash sudo apt-get install git git config --global user.name "Your Name" git config --global user.email "youremail@domain.com" ``` 3. Install Node.js, nvm, yarn ```bash sudo apt-get install curl curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/master/install.sh | bash corepack enable ``` Close and reopen your terminal to start using nvm. :::caution Note Avoid using Docker on WSL as it adds an extra layer of complexity. ::: --- ## Step 1: Git Clone In your terminal, run the following command. :::info Note It's better to use SSH for this step. If you already haven't set up SSH keys, please do so first. You can learn more about it [here](https://docs.github.com/en/authentication/connecting-to-github-with-ssh/about-ssh). ::: ```bash git clone git@github.com:twentyhq/twenty.git ``` ```bash git clone https://github.com/twentyhq/twenty.git ``` ## Step 2: Place yourself at the root of the project ```bash cd twenty ``` All commands in the following steps should be run from the root of the project. ## Step 3: Set up PostgreSQL Database To install PostgreSQL with a `default` and a `test` database, and provision these databases with a user `twenty` (password: `twenty`), follow the steps below: Option 1: To provision your database locally: ```bash make postgres-on-linux ``` Option 2: If you have docker installed: ```bash make postgres-on-docker ``` This will create a Docker container, exposing a PostgresSQL instance at [http://localhost:5432](http://localhost:5432). You can access this using `twenty` postgres user (password: `twenty`) Option 1: To provision your database locally: ```bash make postgres-on-macos-intel #for intel architecture make postgres-on-macos-arm #for M1/M2/M3 architecture ``` Option 2: If you have docker installed: ```bash make postgres-on-docker ``` This will create a Docker container, exposing a PostgresSQL instance at [http://localhost:5432](http://localhost:5432). You can access this using `twenty` postgres user (password: `twenty`) It's better to provision your database locally: ```bash make postgres-on-linux ``` This will create a Docker container, exposing a PostgresSQL instance at [http://localhost:5432](http://localhost:5432). You can access this using `twenty` postgres user (password: `twenty`) ## Step 4: Setup environment variables Twenty requires you to set some environment variables. Locally, you should set them through a `.env` file. To do so, make copies of the `.env.example` files in `/front` and `/server`: ```bash cp ./packages/twenty-front/.env.example ./packages/twenty-front/.env cp ./packages/twenty-server/.env.example ./packages/twenty-server/.env ``` ## Step 5: Installing dependencies :::info Use `nvm` to install the correct `node` version. The `.nvmrc` ensures all contributors use the same version. ::: To build Twenty server and seed some data into your database, run the following commands: ```bash nvm install #recommended nvm use #recommended yarn ``` ## Step 6: Running the project Setup your database with the following command: ```bash yarn nx database:init twenty-server ``` Start the server and the frontend: ```bash yarn nx start:dev twenty-server yarn nx start twenty-front ``` Twenty's server will be up and running at [http://localhost:3000/graphql](http://localhost:3000/graphql). Twenty's frontend will be running at [http://localhost:3001](http://localhost:3001). Just login using the seeded demo account: `tim@apple.dev` (password: `Applecar2025`) to start using Twenty.
