# Deploying ToolJet on Heroku
*If you have any questions feel free to join our [Slack Community](https://tooljet.com/slack) or send us an email at hello@tooljet.com.*
### Follow the steps below to deploy ToolJet on Heroku:
1. Click the button below to start one click deployment.
2. On Heroku tab, you'll be asked to provide an `App name` and `Choose a region`. Enter the name for your deployment and select the region according to your choice.
3. Now let's enter the `Config vars` to configure additional [environment variables](/docs/setup/env-vars) that are required for the installation.
- **LOCKBOX_MASTER_KEY**: ToolJet server uses lockbox to encrypt datasource credentials. You should set the environment variable LOCKBOX_MASTER_KEY with a 32 byte hexadecimal string. If you have OpenSSL installed, you can run the command `openssl rand -hex 32` to generate the key.
- **NODE_ENV**: By default NODE_ENV is set to production.
- **NODE_OPTIONS**: Node options are configured to increase node memory to support app build.
- **SECRET_KEY_BASE**: ToolJet server uses a secure 64 byte hexadecimal string to encrypt session cookies. You should set the environment variable SECRET_KEY_BASE. If you have OpenSSL installed, you can run the command `openssl rand -hex 64` to generate the key.
- **TOOLJET_HOST**: Public URL of ToolJet installation. This is usually `https://.herokuapp.com`.
- **TOOLJET_SERVER_URL**: URL of ToolJet server installation. (This is same as the TOOLJET_HOST for Heroku deployments)
4. Click on `Deploy app` button at the bottom to initiate the build.
5. After the successful build, you'll see two buttons at the bottom: `Manage App` and `View`. Click on the `View` to open the app or click on `Manage App` to configure any settings.
:::tip
ToolJet server and client can be deployed as standalone applications. If you do not want to deploy the client on Heroku, modify `package.json` accordingly. We have a [guide](/docs/setup/client) on deploying ToolJet client using services such as Firebase.

### Deploying Tooljet Database
If you intend to use this feature, you'd have to set up and deploy PostgREST server which helps querying ToolJet Database.
This feature is only enabled if `ENABLE_TOOLJET_DB` is set to `true` in the Tooljet application.
#### Follow the steps below to deploy ToolJet Database on Heroku:
:::note
Please install Heroku CLI on your local machine. Please refer Heroku CLI installation steps [**here**](https://devcenter.heroku.com/articles/heroku-cli).
:::
1. **Create a new Heroku app using the PostgREST buildpack**
1.1 Create a folder with your app name. Please give a unique name to the app.
```bash
mkdir ${YOUR_PGRST_APP_NAME}
cd $${YOUR_PGRST_APP_NAME}
git init
```
1.2 Add PostgREST buildpack to your app.
```bash
heroku apps:create ${YOUR_PGRST_APP_NAME} --buildpack https://github.com/PostgREST/postgrest-heroku.git
heroku git:remote -a ${YOUR_PGRST_APP_NAME}
```
2. **Attach the Tooljet app’s PostgreSQL database your Tooljet database app**
`${HEROKU_PG_DB_NAME` Should be the name of the PostgreSQL created by the Tooljet app.
You can get the `${HEROKU_PG_DB_NAME` of the Tooljet application from the Resources tab under Heroku Postgres attachments as shown below. (eg: `${HEROKU_PG_DB_NAME = postgresql-transparent-24158` ).
```bash
heroku addons:attach ${HEROKU_PG_DB_NAME} -a ${YOUR_PGRST_APP_NAME}
```
3. **Create a Procfile**
:::info
The Procfile is a simple text file that is named Procfile without a file extension. For example, Procfile.txt is not valid.
:::
Please paste the below string within the Procfile file.
```bash
web: PGRST_SERVER_HOST=0.0.0.0 PGRST_SERVER_PORT=${PORT} PGRST_DB_URI=${PGRST_DB_URI:-${DATABASE_URL}} ./postgrest-${POSTGREST_VER}
```
4. **Set environment variables**
You can also refer environment variable [**here**](/docs/setup/env-vars/#enable-tooljet-database--optional-).
:::tip
If you have openssl installed, you can run the
command `openssl rand -hex 32` to generate the value for `PGRST_JWT_SECRET`.
If this parameter is not specified, PostgREST will refuse authentication requests.
:::
```bash
heroku config:set PGRST_JWT_SECRET=
heroku config:set POSTGREST_VER=10.0.0
```
You can also refer environment variable [**here**](/docs/setup/env-vars/#enable-tooljet-database--optional-).
5. **Build and deploy your app**
```bash
git add Procfile
git commit -m "PostgREST on Heroku"
git push --set-upstream heroku main
```
Your Heroku app should be live at `${YOUR_APP_NAME}.herokuapp.com`.
6. **Additional environment variables for Tooljet application**
Please enter the below env variables in the Tooljet application, under the setting tab. You can also refer environment variable [**here**](/docs/setup/env-vars/#enable-tooljet-database--optional-).
## Upgrading to the Latest Version
The latest version includes architectural changes and, hence, comes with new migrations.
If this is a new installation of the application, you may start directly with the latest version. This guide is not required for new installations.
#### Prerequisites for Upgrading to the Latest Version:
- It is **crucial to perform a comprehensive backup of your database** before starting the upgrade process to prevent data loss.
- Ensure that your current version is v2.23.0-ee2.10.2 before upgrading.
- Users on versions earlier than v2.23.0-ee2.10.2 must first upgrade to this version before proceeding to the latest version.
For specific issues or questions, refer to our **[Slack](https://tooljet.slack.com/join/shared_invite/zt-25438diev-mJ6LIZpJevG0LXCEcL0NhQ#)**.
