# V lang example web server
2+
3+
Server "competition" *Web Framework Benchmarks*: https://www.techempower.com/benchmarks
4+
5+
It designed to demonstrate how to use <a href="https://modules.vlang.io/veb.html">Veb</a>'s built-in features to create a web application. It's a slightly more complex example due to the fact i tried to reuse code for multiple scenarios.
6+
7+
> NOTE: Cache test still to be properly implemented
8+
9+
## Scenarios
10+
11+
We created some scenarios. One on each folder. All scenarios use **Veb** server, the <a href="https://vlang.io">V</a> lang built-in web framework.
12+
13+
### Veb with Postgres (veb-pg/)
14+
15+
```
16+
v run veb-pg/
17+
```
18+
19+
### Veb with Postgres and ORM (veb-pg-orm/) (TBD)
20+
21+
```
22+
v run veb-pg-orm/
23+
```
24+
25+
### Veb with MySQL/MariaDB (veb-my/) (TBD)
26+
27+
```
28+
v run veb-my/
29+
```
30+
31+
### Veb with MySQL/MariaDB and ORM (veb-my-orm/) (TBD)
32+
33+
```
34+
v run veb-my-orm/
35+
```
36+
37+
## Local Setup
38+
39+
in order to test the servers locally, you will need a database server and a database client. using container, you can use:
40+
41+
### Postgres:
42+
43+
```
44+
docker run --name benckmark-postgres \
45+
-e POSTGRES_USER=benchmarkdbuser \
46+
-e POSTGRES_PASSWORD=benchmarkdbpass \
47+
-e POSTGRES_DB=hello_world \
48+
-p 5432:5432 \
49+
-d techempower/postgres:latest
50+
```
51+
52+
### MySQL/MariaDB:
53+
54+
```
55+
docker run --name benckmark-mysql \
56+
-e MYSQL_ROOT_PASSWORD=benchmarkdbpass \
57+
-e MYSQL_USER=benchmarkdbuser \
58+
-e MYSQL_PASSWORD=benchmarkdbpass \
59+
-e MYSQL_DATABASE=hello_world \
60+
-p 3306:3306 \
61+
-d techempower/mysql:latest
62+
```
