Examples

Get started with these practical examples to understand how Chimera works and how you can tailor it for your development workflows.

Basic Example

Create a simple data.json mock:

{
  "/api/products": [
    { "id": 1, "name": "Laptop", "price": 1200 },
    { "id": 2, "name": "Keyboard", "price": 100 }
  ]
}

• Directoryproject/

  • data.json

Run Chimera:

chimera-cli.exe --path data.json

Visit http://localhost:8080/api/products to see the mock response.

---

Run a HTTP mock server

chimera-cli.exe --path data.json http

This runs a mock http server

---

Run a Websocket mock server

chimera-cli.exe --path data.json websocket

This runs a mock websocket server

---

Simulate Latency

chimera-cli.exe --path data.json http --latency 300

This adds a 300ms delay to all responses.

---

Paginate Results

chimera-cli.exe --path data.json http --page 2

Returns 2 results per page.

---

Sorted Responses

chimera-cli.exe --path data.json http --sort api/products desc id

Sorts the /api/products endpoint in descending order by attribute id.

---

Using a Schema for Data AutoGeneration

chimera-cli.exe --path schema.json http -X

Example schema.json:

{
    "routes": [
        {
            "path": "api/v2/comment",
            "no_of_entries": 5,
            "schema": {
                "id": "id",
                "user": "name",
                "message": "lorem"
            },
            "null_percentage": 0
        }
    ]
}

This generates 5 random comments.

---

Combine Flags

chimera-cli.exe --path schema.json http -X --port 4000 --latency 150 --sort api/data asc id

Combines data auto-generation, sorting, and latency as a http mock server on on port 4000.
