One-click deploy

What is one-click deploy?

One-click deploy is a feature that is available once a platform is properly configured and a supported device is connected to the computer. Since things can go wrong at many levels (platform may not be configured correctly, SDK may be incorrectly installed, device may be improperly configured, etc.), it's good to let the user know that it exists.

After adding an Android export preset marked as Runnable, Redot can detect when a USB device is connected to the computer and offer the user to automatically export, install and run the project (in debug mode) on the device. This feature is called one-click deploy.

Note

One-click deploy is only available once you've added an export template marked as Runnable in the Export dialog. You can mark several export presets as runnable, but only one preset per platform may be marked as runnable. If you mark a second preset in a given platform as runnable, the other preset will no longer be marked as runnable.

Supported platforms

• Android: Exports the project with debugging enabled and runs it on the connected device.

  • Make sure to follow the steps described in Exporting for Android. Otherwise, the one-click deploy button won't appear.

  • If you have more than one device connected, Redot will ask you which device the project should be exported to.

• iOS: Exports the project with debugging enabled and runs it on the connected device or simulator.

  • Make sure to follow the steps described in Exporting for iOS. Otherwise, the one-click deploy button won't appear.

  • For each new bundle identifier, export the project, open it in the Xcode, and build at least once to create new provisioning profile or create a provisioning profile in the Apple Developer account dashboard.

  • If you have more than one device connected, Redot will ask you which device the project should be exported to.

• Desktop platforms: Exports the project with debugging enabled and runs it on the remote computer via SSH.

• Web: Starts a local web server and runs the exported project by opening the default web browser. This is only accessible on localhost by default. See Troubleshooting for making the exported project accessible on remote devices.

Using one-click deploy

• Android:

  • Enable developer mode on your mobile device then enable USB debugging in the device's settings.

  • After enabling USB debugging, connect the device to your PC using a USB cable.

  • For advanced users, it should also be possible to use wireless ADB.

• iOS:

  • Install Xcode, accept Xcode license and login with your Apple Developer account.

  • If you are using Xcode 14 or earlier, install ios-deploy and set path to ios-deploy in the Editor Settings (see Export ⇾ iOS ⇾ iOS Deploy).

  • For running on device:

    • Pair your mobile device with a Mac.

    • Enable developer mode on your device.

    • Device can be connected via USB or local network.

    • Make sure the device is on the same local network and a correct network interface is selected in the editor settings (see Network ⇾ Debug ⇾ Remote Host). By default, the editor is listening for localhost connections only.

  • For running in simulator:

    • Install and start simulator from the Xcode.

  • Device screen should be unlocked.

• Desktop platforms:

  • Enable SSH Remote Deploy and configure connection settings in the project export setting.

• Make sure there is an export preset marked as Runnable for the target platform (Android, iOS or Web).

• If everything is configured correctly and with no errors, platform-specific icons will appear in the top-right corner of the editor.

• Click the button to export to the desired platform in one click.

Troubleshooting

Android

If you can't see the device in the list of devices when running the adb devices command in a terminal, it will not be visible by Redot either. To resolve this:

• Check if USB debugging is enabled and authorized on the device. Try unlocking your device and accepting the authorization prompt if you see any. If you can't see this prompt, running adb devices on your PC should make the authorization prompt appear on the device.

• Try revoking the debugging authorization in the device's developer settings, then follow the steps again.

• Try using USB debugging instead of wireless debugging or vice versa. Sometimes, one of those can work better than the other.

• On Linux, you may be missing the required udev rules for your device to be recognized.

Web

By default, the web server started by the editor is only accessible from localhost. This means the web server can't be reached by other devices on the local network or the Internet (if port forwarding is set up on the router). This is done for security reasons, as you may not want other devices to be able to access the exported project while you're testing it. Binding to localhost also prevents a firewall popup from appearing when you use one-click deploy for the web platform.

To make the local web server accessible over the local network, you'll need to change the Export > Web > HTTP Host editor setting to 0.0.0.0. You will also need to enable Export > Web > Use TLS as SharedArrayBuffer requires the use of a secure connection to work, unless connecting to localhost. However, since other clients will be connecting to a remote device, the use of TLS is absolutely required here.

To make the local web server accessible over the Internet, you'll also need to forward the Export > Web > HTTP Port port specified in the Editor Settings (8060 by default) in TCP on your router. This is usually done by accessing your router's web interface then adding a NAT rule for the port in question. For IPv6 connections, you should allow the port in the router's IPv6 firewall instead. Like for local network devices, you will also need to enable Export > Web > Use TLS.

Note

When Use TLS is enabled, you will get a warning from your web browser as Redot will use a temporary self-signed certificate. You can safely ignore it and bypass the warning by clicking Advanced and then Proceed to (address).

If you have an SSL/TLS certificate that is trusted by browsers, you can specify the paths to the key and certificate files in the Export > Web > TLS Key and Export > Web > TLS Certificate. This will only work if the project is accessed through a domain name that is part of the TLS certificate.
