micro-jaymock

Tiny API mocking microservice for generating fake JSON data.

Usage

• Send a POST request to https://jaymock.now.sh/ (or https://micro-jaymock.now.sh/) with your JSON template (see jaymock.populate's template parameter) as your request's body.

Examples

Using curl:

~ ❯❯❯ curl -X POST \
        -d '{ "firstName": "name.firstName", "lastName": "name.lastName" }' \
        https://jaymock.now.sh
{"firstName":"Isaac","lastName":"Schultz"}

Using httpie:

~ ❯❯❯ http -b POST https://jaymock.now.sh \
        firstName=name.firstName lastName=name.lastName ssn=chance.ssn \
        _repeat:=3
[
    {
        "firstName": "Jalyn",
        "lastName": "Weimann",
        "ssn": "493-64-4894"
    },
    {
        "firstName": "Alvah",
        "lastName": "Ziemann",
        "ssn": "567-92-8024"
    },
    {
        "firstName": "Bennett",
        "lastName": "Russel",
        "ssn": "356-24-9256"
    }
]

Using request (Node.js):

const request = require('request')
const template = {
    firstName: 'name.firstName',
    lastName: 'name.lastName',
    ipAddresses: 'internet.ip|2'
}
request.post({url: 'https://jaymock.now.sh', json: template}, (error, response, body) => {
    if (error) {
        /* Handle error */
        console.error(error)
    }
    console.log(body)
    /*
        {
            firstName: 'Kaley',
            lastName: 'Muller',
            ipAddresses: [ '118.171.253.32', '193.234.186.225' ]
        }
    */
})

Using got (Node.js):

const got = require('got');
const template = {
    name: 'fake({{name.lastName}}, {{name.firstName}} {{name.suffix}})',
    ssn: 'chance.ssn',
    knownAddresses: {
        street: 'address.streetAddress',
        city: 'address.city',
        zipCode: 'address.zipCode',
        _repeat: 2
    }
};
(async () => {
    const {body} = await got.post('https://jaymock.now.sh', {
        json: template,
        responseType: 'json'
    });
    console.log(body);
    /*
        {
            name: 'Goodwin, Libby II',
            ssn: '368-52-3834',
            knownAddresses: [
                {
                    street: '42483 Citlalli Viaduct',
                    city: 'West Joeybury',
                    zipCode: '43966-8850'
                },
                {
                    street: '36297 Estella Throughway',
                    city: 'South Claudie',
                    zipCode: '39189-1653'
                }
            ]
        }
    */
})();

Using requests (Python 3):

import requests, json
template = {
    "accounts": {
        "name": "finance.accountName",
        "iban": "finance.iban",
        "bic": "finance.bic",
        "currentBalance": "finance.amount",
        "currency": "finance.currencyName",
        "_repeat": 2
    }
}
r = requests.post('https://jaymock.now.sh', data = json.dumps(template))
parsedFakeData = json.loads(r.text) # parse for pretty-printing
print(json.dumps(parsedFakeData, indent=4, sort_keys=True))
"""
    {
        "accounts": [
            {
                "bic": "WNRUMKJ1",
                "currency": "Turkish Lira",
                "currentBalance": "37.49",
                "iban": "CY70805008804937709053145O66",
                "name": "Credit Card Account"
            },
            {
                "bic": "LTJUMXQ1",
                "currency": "Somoni",
                "currentBalance": "98.10",
                "iban": "FI1000486540190178",
                "name": "Home Loan Account"
            }
        ]
    }
"""

Development

First, clone the repository and install its dependencies:

~ ❯❯❯ git clone https://github.com/Meeshkan/micro-jaymock.git
~ ❯❯❯ cd micro-jaymock/
~/micro-jaymock ❯❯❯ npm install

Subsequently, start the development server:

~/micro-jaymock ❯❯❯ npm run dev

You can then access the service by navigating to localhost:3000.

Alternatively, you can download jaymock-cli (by running ~ ❯❯❯ npm i -g jaymock-cli), which allows you to run the development server and, consequently, mock a fake API 'globally' (by simply executing ~ ❯❯❯ jaymock --server).

Deployment

Alternatively, to deploy micro-jaymock manually:

First, download now:

~ ❯❯❯ npm install -g now

Then, run now from within the micro-jaymock directory:

~/micro-jaymock ❯❯❯ now
