Drakov API Blueprint Mock Server

Mock server that implements the API Blueprint specification:

Note on Dependencies

You will need to have g++ and make installed on your system so npm install can compile the Snow Crash library.

Installation instructions

npm install -g drakov

Running

drakov -f <glob expression to your md files> -s <comma delimited list of static file paths> -p <server port>

Argument Notes:

Glob expression is required
If a list of static file paths are provided, then Drakov will proxy the static files
Server port is optional and defaults to 3000
CORS headers are sent by default, you need to use the --disableCORS switch/property

Examples

With only a glob expression

drakov -f "../com/foo/contracts/*.md"

With glob expression and single static path

drakov -f "../com/foo/contracts/*.md" -s "../path/to/static/files"

With glob expression and multiple static paths (must be comma delimited with no spaces)

drakov -f "../com/foo/contracts/*.md" -s "../path/to/static/files" -s "../second/path/to/static/files"

With globa expression and static path that has a specific mount point

drakov -f "../com/foo/contracts/*.md" -s "../path/to/static/files=/www/path"

With globa expression and static path that has a specific mount point with different path mount delimiter

drakov -f "../com/foo/contracts/*.md" -s "../path/to/static/files:/www/path" -d ":"

With glob expression and specified server port

drakov -f "../com/foo/contracts/*.md" -p 4007

CORS Header

By default a CORS header is sent, you can disable it with the --disableCORS switch.

drakov -f "../com/foo/contracts/*.md" --disableCORS

SSL Support

To enable SSL you must provide both key and certificate. Use parameters --sslKeyFile and --sslCrtFile to specify the path to your key and certificate files. Once SSL is enabled Drakov will only respond to HTTPS requests.

drakov -f "../com/foo/contracts/*.md" --sslKeyFile="./ssl/server.key" --sslCrtFile="./ssl/server.crt"

Stealth Mode

In some cases you may wish to suppress the logging output of Drakov. To do so, run is with the --stealthmode options.

drakov -f "../com/foo/contracts/*.md" --stealthmode

Response Delay

In some case you may want to force Drakov to delay sending a response. To do this simple use the --delay argument followed by a number (ms).

drakov -f "../com/foo/contracts/*.md" --delay 2000

Allow Methods Header

For HTTP methods such as DELETE, you may want Drakov to return them in the appropriate methods allow header. You can do this using the --method argument

drakov -f "../com/foo/contracts/*.md" --method DELETE

drakov -f "../com/foo/contracts/*.md" --method DELETE --method OPTIONS

Using as a Node.js module

var drakov = require('drakov');

var argv = {
    sourceFiles: 'path/to/files/**.md',
    serverPort: 3000,
    staticPaths: [
        '/path/to/static/files',
        '/another/path/to/static/files',
        '/path/to/more/files=/mount/it/here'
    ],
    stealthmode: true,
    disableCORS: true,
    sslKeyFile: '/path/to/ssl/key.key',
    sslCrtFile: '/path/to/ssl/cert.crt',
    delay: 2000,
    method: ['DELETE','OPTIONS']
};

drakov.run(argv, function(){
    // started Drakov
    drakov.stop(function() {
        // stopped Drakov
    });
});

Using as an Express middleware

Due to protagonist parsing being async, we need to setup the middleware with an init function

var drakovMiddleware = require('drakov');

var argv = {
    sourceFiles: 'path/to/files/**.md',
    serverPort: 3000,
    staticPaths: [
        '/path/to/static/files',
        '/another/path/to/static/files',
        '/path/to/more/files=/mount/it/here'
    ],
    stealthmode: true,
    disableCORS: true,
    sslKeyFile: '/path/to/ssl/key.key',
    sslCrtFile: '/path/to/ssl/cert.crt',
    delay: 2000,
    method: ['DELETE','OPTIONS']
};

var app = express();
drakovMiddleware.init(app, argv, function(err, middlewareFunction) {
    if (err) {
        throw err;
    }
    app.use(middlewareFunction);
    app.listen(argv.serverPort);
});

FAQ

Q: If I have multiple requests/responses on the same API endpoint, which response will I get?

A: Drakov will respond with the first response matching the request body for that API endpoint.

Q: If I have multiple responses on a single request, which response will I get?

A: Drakov will respond with the first response.

Q: Drakov is too loud (outputting too much logging), can I turn off request and API responses?

A: You can suppress all but the startup output of Drakov with --stealthmode.

CONTRIBUTING

Pull requests with patches for fixes and enhancements are very welcome. We have a few requirements that will help us to quickly assess your contributions.

If you have any ideas or questions you are welcome to post an issue.

Code conventions

Setup your editor to use the .editorconfig and .jshintrc files included in the project
We use 4 spaces for tabs
Most of the style issues should be resolve as long as you run npm test and run against the jshinting rules
We prefer readability over compact code

Logging in your code

Include the lib/logger module and use logger.log(), this allows your logging be properly disabled in Drakov's stealth mode
Always have a type qualifier in square brackets in from of your message in white, logger.log('[TYPE]'.white, 'Something is happening');`
We don't have any guidelines for how to log, except that you should have your type a different colour from your actual message (better logging is in our roadmap)

Functionality that adds CLI arguments

Make sure you add the new argument property to the optimistOptions object in the arguments module

Middleware functionality

For functionality that does something with the request object add code to the request module
For functionality that does something with the response object add code to the response module

Testing

If your contribution deals with API Blueprint request/response behaviour add an example into an existing or new markdown file in the test/example/md directory
Always add a test in test/api for request/response behaviour tests, or test/unit if it is a unit test
All test specification files must end in -test.js
Always run npm test before you submit your build request
