LLGo wrapper of libuv
=====
## How to install
### on macOS (Homebrew)
```sh
brew install libuv
```
### on Linux (Debian/Ubuntu)
```sh
apt-get install -y libuv1-dev
```
### on Linux (CentOS/RHEL)
```sh
yum install -y libuv-devel
```
### on Linux (Arch Linux)
```sh
pacman -S libuv
```
## Demos
The `_demo` directory contains our demos (it start with `_` to prevent the `go` command from compiling it):
* [async_fs](_demo/async_fs/async_fs.go): a simple async file read demo
* [echo_server](_demo/echo_server/echo_server.go): a basic async tcp echo server
### How to run demos
To run the demos in directory `_demo`:
```sh
cd <demo-directory> # eg. cd _demo/sqlitedemo
llgo run .
```
