--- title: Local Setup icon: TbDeviceDesktop image: /images/user-guide/fields/field.png info: Mostly for contributors or curious developers --- Follow this guide if you would like to setup the project locally to contribute. ## 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) `npm` won't work, you should use `yarn` instead. Yarn is now shipped with Node.js, so you don't need to install it separately. You 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 nvm, node.js and yarn Use `nvm` to install the correct `node` version. The `.nvmrc` ensures all contributors use the same version. ```bash sudo apt-get install curl curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/master/install.sh | bash ``` Close and reopen your terminal to use nvm. Then run the following commands. ```bash nvm install # installs recommended node version nvm use # use recommended node version corepack enable ``` --- ## Step 1: Git Clone In your terminal, run the following command. If you haven't already set up SSH keys, you can learn how to do so [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: Position yourself at the root ```bash cd twenty ``` You should run all commands in the following steps from the root of the project. ## Step 3: Set up a PostgreSQL Database You can access the database at [localhost:5432](localhost:5432), with user `twenty` and password `twenty` . Option 1: To provision your database locally: Use the following link to install Postgresql on your Linux machine: [Postgresql Installation](https://www.postgresql.org/download/linux/) ```bash psql postgres -c "CREATE DATABASE \"default\";" -c "CREATE DATABASE test;" -c "CREATE USER twenty PASSWORD 'twenty';" -c "ALTER ROLE twenty superuser;" ``` Note: You might need to add `sudo -u postgres` to the command before `psql` to avoid permission errors. Option 2: If you have docker installed: ```bash make postgres-on-docker ``` Option 1: To provision your database locally with `brew`: ```bash brew install postgresql@16 export PATH="/opt/homebrew/opt/postgresql@16/bin:$PATH" psql postgres -c "CREATE DATABASE \"default\";" -c "CREATE DATABASE test;" -c "CREATE USER twenty PASSWORD 'twenty';" -c "ALTER ROLE twenty superuser;" ``` Option 2: If you have docker installed: ```bash make postgres-on-docker ``` All the following steps are to be run in the WSL terminal (within your virtual machine) Option 1: To provision your Postgresql locally: Use the following link to install Postgresql on your Linux virtual machine: [Postgresql Installation](https://www.postgresql.org/download/linux/) ```bash psql postgres -c "CREATE DATABASE \"default\";" -c "CREATE DATABASE test;" -c "CREATE USER twenty PASSWORD 'twenty';" -c "ALTER ROLE twenty superuser;" ``` Note: You might need to add `sudo -u postgres` to the command before `psql` to avoid permission errors. Option 2: If you have docker installed: Running Docker on WSL adds an extra layer of complexity. Only use this option if you are comfortable with the extra steps involved, including turning on [Docker Desktop WSL2](https://docs.docker.com/desktop/wsl). ```bash make postgres-on-docker ``` ## Step 4: Set up a Redis Database (cache) Twenty requires a redis cache to provide the best performances Option 1: To provision your Redis locally: Use the following link to install Redis on your Linux machine: [Redis Installation](https://redis.io/docs/latest/operate/oss_and_stack/install/install-redis/install-redis-on-linux/) Option 2: If you have docker installed: ```bash make redis-on-docker ``` Option 1: To provision your Redis locally with `brew`: ```bash brew install redis ``` Option 2: If you have docker installed: ```bash make redis-on-docker ``` Option 1: To provision your Redis locally: Use the following link to install Redis on your Linux virtual machine: [Redis Installation](https://redis.io/docs/latest/operate/oss_and_stack/install/install-redis/install-redis-on-linux/) Option 2: If you have docker installed: ```bash make redis-on-docker ``` ## Step 5: Setup environment variables Use environment variables or `.env` files to configure your project. Copy 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 6: Installing dependencies To build Twenty server and seed some data into your database, run the following command: ```bash yarn ``` ## Step 7: Running the project Start your redis server: Depending on your Linux distribution, Redis server might be started automatically. If not, check the [Redis installation guide](https://redis.io/docs/latest/operate/oss_and_stack/install/install-redis/) for your distro. ```bash brew services start redis ``` Depending on your Linux distribution, Redis server might be started automatically. If not, check the [Redis installation guide](https://redis.io/docs/latest/operate/oss_and_stack/install/install-redis/) for your distro. Setup your database with the following command: ```bash npx nx database:reset twenty-server ``` Start the server, the worker and the frontend services: ```bash npx nx start twenty-server npx nx worker twenty-server npx nx start twenty-front ``` Alternatively, you can start all services at once: ```bash npx nx start ``` Twenty's server will be up and running at [http://localhost:3000](http://localhost:3000). The GraphQL API can be accessed at [http://localhost:3000/graphql](http://localhost:3000/graphql), and the REST API can be reached at [http://localhost:3000/rest](http://localhost:3000/rest). Twenty's frontend will be running at [http://localhost:3001](http://localhost:3001). Just log in using the seeded demo account: `tim@apple.dev` (password: `Applecar2025`) to start using Twenty. ## Troubleshooting #### CR line breaks found [Windows] This is due to the line break characters of Windows and the git configuration. Try running: ``` git config --global core.autocrlf false ``` Then delete the repository and clone it again. #### Missing metadata schema During Twenty installation, you need to provision your postgres database with the right schemas, extensions, and users. If you're successful in running this provisioning, you should have `default` and `metadata` schemas in your database. If you don't, make sure you don't have more than one postgres instance running on your computer. #### Cannot find module 'twenty-emails' or its corresponding type declarations. You have to build the package `twenty-emails` before running the initialization of the database with `npx nx run twenty-emails:build` #### Missing twenty-x package Make sure to run yarn in the root directory and then run `npx nx server:dev twenty-server`. If this still doesn't work try building the missing package manually. #### Lint on Save not working This should work out of the box with the eslint extension installed. If this doesn't work try adding this to your vscode setting (on the dev container scope): #### While running `npx nx start` or `npx nx start twenty-front`, Out of memory error is thrown In `packages/twenty-front/.env` uncomment `VITE_DISABLE_TYPESCRIPT_CHECKER=true` and `VITE_DISABLE_ESLINT_CHECKER=true` to disable background checks thus reducing amount of needed RAM. ``` "editor.codeActionsOnSave": { "source.fixAll.eslint": "explicit" } ```
