# Learn Expressjs
limbanga is learning how to use express in ubuntu :)
Here is his note
## Install node
First step, I download nodejs from node homepage in *.tar.xz format.
I have unziped this file using bash scripts
```bash
tar -xfv
```
I recieved a folder contain nodejs code.
I have moved it into my /home/ folder for management.
Then I add bin folder's path to ~/.bashrc so that I can access nodejs code though my terminal.
For example:
```bash
export PATH=$PATH:/home/lim/node-v20.17.0-linux-x64/bin
```
It can be different rely on where your store the folder
Now restart your terminal and start coding
```bash
source ~/.bashsrc
```
If your installation is succeed, this code should print node version
```bash
node -v
```
## Initialize node project

```bash
npm init
```
You'll see package.json file containing project information.

const app = express();
const port = 3000;
app.get('/', (req, res) => {
res.send('Hello World!');
});
