Testing out the Rust framework Actix-Web to create a JSON API CRUD Web App.
## API Demo
### Get Users
```
curl -X GET http://localhost:7800/api/users/get/1
```
```
{
"name": "user1",
"registration_date": "2020-05-09T06:17:26"
}
```
```
curl -X GET http://localhost:7800/api/users/get
```
```
[
{
"name": "user1",
"registration_date": "2020-05-09T06:17:26"
},
{
"name": "user2",
"registration_date": "2020-05-12T12:43:13"
},
{
"name": "user3",
"registration_date": "2020-05-15T07:47:50"
}
]
```
### Create User
```
curl -H "content-type: application/json" \
-X POST \
-i http://localhost:7800/do_registration \
--data '{"name":"user4","password":"test"}'
```
```
[
{
"name": "user1",
"registration_date": "2020-05-09T06:17:26"
},
{
"name": "user2",
"registration_date": "2020-05-12T12:43:13"
},
{
"name": "user3",
"registration_date": "2020-05-15T07:47:50"
},
{
"name": "user4",
"registration_date": "2020-08-01T05:04:05"
}
]
```
### DTO Validation
```
curl -H "content-type: application/json" \
-X POST \
-i http://localhost:7800/do_registration \
--data '{"name":"abc","password":"test"}' # min length for name is 4
```
```
ValidationErrors({"name": Field([ValidationError { code: "length", message: None, params: {"value": String("abc"), "min": Number(4), "max": Number(10)} }])})
```
## Memory Usage
Memory usage as compared to interpreted languages was my primary motivation for looking into rust as a backend language. As of writing, the demo app uses less than 50MB of memory.
