# Server
4+
5+
## Getting started
6+
7+
First you'll need to get the source of the project. Do this by cloning the whole JSPrep repository:
8+
9+
`git clone [email protected]:olga-f/capstone.git`
10+
11+
`cd server`
12+
13+
#### Create a virtual environment in which we can install the dependencies
14+
15+
`python -m venv env`
16+
17+
`source env/Scripts/activate`
18+
19+
#### Now we can install our dependencies:
20+
21+
`pip install -r requirements.txt`
22+
23+
#### Setup a mongodb connection and create a database.
24+
25+
> 🔹 [MongoDB Atlas] (https://www.mongodb.com/) offers Free Shared Clusters.
26+
27+
1. Add `.env` file with your mongodb credentials to the `server` folder.
28+
29+
```
30+
SECRET_KEY=gozaXXXXXXXXXXXXXXXXXXXXXXXX
31+
DEBUG=True
32+
_MONGODB_URI=mongodb+srv://XXXXXXX:[email protected]/test?retryWrites=true&w=majority
33+
34+
```
35+
36+
2. Run the following command:
37+
38+
`python manage.py migrate`
39+
40+
3. Start the server:
41+
42+
`python manage.py runserver`
43+
44+
Now head on over to http://127.0.0.1:8000/graphql and run some queries!
45+
46+
For example:
47+
48+
```
49+
mutation($input: BikeInput!) {
50+
createBike(bikeData: $input) {
51+
bike {
52+
name
53+
brand
54+
year
55+
size
56+
wheelSize
57+
type
58+
}
59+
}
60+
}
61+
62+
```
63+
query variables:
64+
```
65+
{
66+
"input": {
67+
"name": "Greg",
68+
"brand": "Variables",
69+
"year": "2021",
70+
"size": "XX",
71+
"wheelSize": 2.0,
72+
"type": "smalltype"
73+
}
74+
}
75+
```
76+
77+
For tests run:
78+
79+
`pytest -v`
