Building and running your own Tuta Mail web client

You can build your own Tuta Mail client and run it locally. Remember that you have to update your Tuta Mail client on your own. If you prefer the auto-update feature, you can use the official mail client.

Pre-requisites:

• An up-to-date version of Git is installed
• Node.js (check package.json engines field for the version)

Build steps:

1. Clone the repository: git clone https://github.com/tutao/tutanota.git
2. Switch into the repository directory: cd tutanota
3. Checkout the latest web release tag: git checkout tutanota-release-xxx
4. run npm ci to install dependencies.
5. Build packages: npm run build-packages
6. Build the web part: node webapp prod
7. Switch into the build directory: cd build
8. Run the local server. Either use node server or python -m SimpleHTTPServer 9000.
9. Open localhost:9000 with your favorite browser (tested: Firefox, Chrome/Chromium, Safari).

Building and running your own Tuta Mail Android app

If you build and install the Tuta Mail Android app by yourself, keep in mind that you will not get updates automatically. If you prefer the auto-update feature, download the app from the Google Play Store or F-Droid. The APK is also published on the GitHub releases page https://github.com/tutao/tutanota/releases. You can add https://github.com/tutao/tutanota/releases.atom to your feed reader to get notified about available updates.

Pre-requisites:

• An up-to-date version of Git is installed
• Node.js (check package.json engines field for the version)
• An up-to-date version of the Android SDK is installed

Build steps:

1. Clone the repository: git clone https://github.com/tutao/tutanota.git
2. Switch into the Tutanota directory: cd tutanota
3. Checkout the latest android release tag: git checkout tutanota-android-release-xxx
4. Install dependencies: npm ci
5. Build packages: npm run build-packages
6. Create a keystore if you don't have one: keytool -genkey -noprompt -keystore MyKeystore.jks -alias tutaKey -keyalg RSA -keysize 2048 -validity 10000 -deststoretype pkcs12 -storepass CHANGEME -keypass CHANGEME -dname "CN=com.example"

run APK_SIGN_ALIAS="tutaKey" APK_SIGN_STORE='MyKeystore.jks' APK_SIGN_STORE_PASS="CHANGEME" APK_SIGN_KEY_PASS="CHANGEME" node android

7. Install the app on your device: adb install -r <path-to-apk> (path as printed by the build script)

Building and running your own Tuta Mail Desktop client

Keep in mind that your own build of Tuta Mail Desktop will not update automatically.

Pre-requisites:

• An up-to-date version of Git is installed.
• Node.js (check package.json engines field for the version)

Preparations:

0. Open a terminal.
1. Clone the repository: git clone https://github.com/tutao/tutanota.git.
2. Switch into the Tutanota directory: cd tutanota
3. Checkout the latest web release tag: git checkout tutanota-release-xxx
4. Run npm ci to install dependencies.

Build:

1. Build packages: npm run build-packages
2. Run node desktop --custom-desktop-release.

The client for your platform will be in build/desktop/. Note that you can add --unpacked to the build command to skip the packaging of the installer. This will yield a directory containing the client that can be run without installation.

Extra Notes:

The windows client uses a native dependency to enable MAPI Support. The source can be found at https://github.com/tutao/mapirs. You can build it yourself before building the client and the build process will pick the artifact up automatically if you structure the projects a such:

parent dir
├── mapirs
└── tutanota-3

Otherwise, the builder will load the current release from https://github.com/tutao/mapirs/releases/latest .
