### Install build requirements
#### Ubuntu
```
-sudo apt install git cargo libssl-dev pkg-config libpq-dev yarn curl gnupg2
+sudo apt install git cargo libssl-dev pkg-config libpq-dev yarn curl gnupg2 espeak
# install yarn
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
brew install node yarn
```
-### Get the source code
+### Get the back end source code
```
git clone https://github.com/LemmyNet/lemmy.git
# or alternatively from gitea
# git clone https://yerbamate.dev/LemmyNet/lemmy.git
```
-All the following commands need to be run either in `lemmy/server` or `lemmy/ui`, as indicated
-by the `cd` command.
-
### Build the backend (Rust)
```
-cd server
cargo build
# for development, use `cargo check` instead)
```
-### Build the frontend (Typescript)
+### Get the front end source code
```
-cd ui
-yarn
-yarn build
+git clone https://github.com/LemmyNet/lemmy-ui.git
```
### Setup postgresql
sudo apt install postgresql
sudo systemctl start postgresql
-# Either execute server/db-init.sh, or manually initialize the postgres database:
+# Either execute db-init.sh, or manually initialize the postgres database:
sudo -u postgres psql -c "create user lemmy with password 'password' superuser;" -U postgres
sudo -u postgres psql -c 'create database lemmy with owner lemmy;' -U postgres
export LEMMY_DATABASE_URL=postgres://lemmy:password@localhost:5432/lemmy
brew services start postgresql
/usr/local/opt/postgres/bin/createuser -s postgres
-# Either execute server/db-init.sh, or manually initialize the postgres database:
+# Either execute db-init.sh, or manually initialize the postgres database:
psql -c "create user lemmy with password 'password' superuser;" -U postgres
psql -c 'create database lemmy with owner lemmy;' -U postgres
export LEMMY_DATABASE_URL=postgres://lemmy:password@localhost:5432/lemmy
### Run a local development instance
```
-# run each of these in a seperate terminal
-cd server && cargo run
-cd ui && yarn start
+cd lemmy
+cargo run
```
-Then open [localhost:4444](http://localhost:4444) in your browser. It will auto-refresh if you edit
-any frontend files. For backend coding, you will have to rerun `cargo run`. You can use
-`cargo check` as a faster way to find compilation errors.
+Then open [localhost:1235](http://localhost:1235) in your browser. To reload back-end changes, you will have to rerun `cargo run`. You can use `cargo check` as a faster way to find compilation errors.
+
+To do front end development:
-To speed up incremental builds, you can add the following to `~/.cargo/config`:
```
-[target.x86_64-unknown-linux-gnu]
-rustflags = ["-Clink-arg=-fuse-ld=lld"]
+cd lemmy-ui
+yarn
+yarn dev
```
+and goto [localhost:1234](http://localhost:1234). Front end saves should rebuild the project.
+
Note that this setup doesn't include image uploads or link previews (provided by pict-rs and
iframely respectively). If you want to test those, you should use the
[Docker development](contributing_docker_development.md).
