Express middleware for mocking restful APIs
npm install --save-dev express-mock-api-middleware
or
yarn add --dev express-mock-api-middleware
In your server.js
, add the following code
const path = require('path');
const express = require('express');
const app = express();
const mockApiMiddleware = require('express-mock-api-middleware')(
path.resolve(__dirname, 'mock'),
{ ignore: ['asm.js'] }
);
app.use('/', mockApiMiddleware);
const host = 'localhost';
const port = 4000;
app.listen(port, host, error => {
if (error) {
console.error(error);
return;
}
console.info(`http://${host}:${port}`);
});
path.resolve(__dirname, 'mock')
is the folder where mock API files are.
{ ignore: ['asm.js'] }
is the options for more flexible glob. (See how to use ignore
in options)
For example in file /mock/user.js
, you can have content
// you can write your own mock logic here
module.exports = {
'GET /api/user/info': {
id: 101,
userName: 'bob',
email: 'bob@gmail.com',
firstName: 'Bob',
lastName: 'Bushee',
},
'POST /api/user/login': (req, res) => {
const { userName, password } = req.body;
if (userName === 'bob' && password === 'password') {
res.send({
success: true,
});
} else {
res.send({
success: false,
});
}
},
'GET /api/product/:id': (req, res) => {
const { id } = req.params;
res.sendFile(path.join(__dirname, `products/${id}.json`));
}
};
Then you can access the mock API from http://localhost:4000/api/user/info
.
Set the DEBUG
environment variable
DEBUG=mock-api
