Basic Usage

1. Create a request file, by default the application recognizes the file as request.json

{
    "protocol": "https", // required (http or https)
    "host": "api.example.com", // required
    "path": "/api/v1/users", // required
    "method": "POST", // required (GET, POST, PUT, DELETE, HEAD, PATCH)
    "headers": {
        "Content-Type": "application/json"
    },
    "body": {
        "name": "John Doe",
        "email": "[e-mail]"
    }
}

2. Execute the request

api-rester call

3. The application will execute the request and save the response in the response.json file

{
    "status": 200,
    "headers": {
        "Content-Type": "application/json"
    },
    "body": {
        "id": 59,
        "name": "John Doe",
        "email": "[e-mail]" 
    }
}

Custom Files

The application supports alternative files to be used as a request and response.

For example, if you have a file called example-file.json and want to receive the response in a different file called example-response.json, you can use it as a request by running the following command:

api-rester call --request-file example-file.json --response-file example-response.json

The application will execute the request and save the response in the example-response.json file.

Environment Variables

The application supports environment variables to be replaced in the request.json file.

For example, if you have an environment variable called API_KEY, you can replace it in the request.json file with ${{API_KEY}}.

{
    // ...
    "path": "/api/v1/users/${{API_KEY}}"
    // ...
}

When you execute the request, the application will replace the ${{API_KEY}} with the value of the API_KEY environment variable.

API_KEY="1234567890" api-rester call

The application will replace the ${{API_KEY}} with the value of the API_KEY environment variable and execute the request.

{
    // ...
    "path": "/api/v1/users/1234567890"
    // ...
}

Example

1. Create a request file called example-file.json

{
    "protocol": "https",
    "host": "api.example.com",
    "path": "/api/v1/users",
    "method": "POST",
    "headers": {
        "Content-Type": "application/json",
        "Authorization": "Bearer ${{API_KEY}}"
    },
    "body": {
        "name": "John Doe",
        "email": "[e-mail]"
    }
}

2. Execute the request

API_KEY=1234567890 api-rester call --request-file example-file.json --response-file example-response.json

3. The application will execute the request and save the response in the example-response.json file

{
    "status": 200,
    "headers": {
        "Content-Type": "application/json"
    },
    "body": {
        "id": 59,
        "name": "John Doe",
        "email": "[e-mail]"
    }
}

Template generation

Api rester can also generate a template of what it expects as a request with this command:

api-rester template

Which you can specify the path with --filename or --f

api-rester template --filename custom_place.json

It will generate this file:

{
  "protocol": "http",
  "host": "localhost:3000",
  "path": "/",
  "method": "GET",
  "headers": {
    "Content-Type": "application/json"
  },
  "body": {
    "message": "Hello world"
  }
}
