If you are here then I assume you already know the purpose of using code-server. So why on phone? Phones these days have become quite powerful. Maybe you have an older laptop lying around. The existence of code-server on Android implies there is at least one use case being fulfilled. So I will not pursue the topic any further.
## Install Termux
Get it from [F-Droid](https://f-droid.org/packages/com.termux/).
Termux is a terminal emulator that allows you to use the command line tools you are familiar with. Root is not needed for our purpose. You can ssh into it or use a bluetooth keyboard if you are not a fan of typing on small screens.
## Install code-server
You can use the [automated script](https://coder.com/docs/code-server/latest/termux#installation) provided by Coder or follow a manual approach as explained below.
In Termux, run `apt update && apt upgrade`. Now we need a few packages to get started. Install them with `apt install build-essential python git nodejs yarn`. Install code-server by running `yarn global add code-server`.
Installing code-server will take a while. It took around 20 minutes on my phone (Snapdragon 665). B
## Running code-server
Start code-server by entering `code-server` in Termux.
By default, it will listen on localhost which is of little help on a small screen. We want to use it on a larger screen like a notebook. There are two ways to achieve this: a) change bind address, and b) use port forwarding.
### Change bind address
Change `bind-addr` to `0.0.0.0:8080` in `~/.config/code-server/config.yaml`.
Now go to your browser (preferably connected to the same network) and enter your phone's IP address with port (which is 8080 in this case). It will ask for a password. Use the one in the config file.
### Use port forwarding
Install `openssh` by running `apt install openssh`. Set your password by running `passwd`. Check username with `whoami`. You may also set up a key pair if you like. In that case, change the config accordingly.
Now start the SSH server by running `sshd`. On remote machine, run the following in your console
```bash
ssh -N -f -L 8080:<your phone's IP address>:8080 <termux username>@<phone's IP address>
```
If you are using key pair, tell ssh to use the key
```bash
ssh -i /path/to/your/key -N -f -L 8080:<your phone's IP address>:8080 <termux username>@<phone's IP address>
```
Open a browser and go to `localhost:8080`.
## Update code-server
Stop code-server, update the above packages, remove code-server (it will not remove config files and stuff) and install code-server. Which means running
```bash
apt update && apt upgrade
yarn global remove code-server
yarn global add code-server
```
