Use body-parser instead of using "JSON.parse(body)" for parsing data

Question

Use body-parser instead of using "JSON.parse(body)" for parsing data

When using express, the middleware "body-parser" can be utilized to automatically parse the incoming body.

However, in the absence of an express router to apply the middleware to, is there a way to implement it for all requests in my chai test file? This would ensure adherence to the DRY (Don't Repeat Yourself) principle.

Currently, I find myself repeating this code in every test:

it('login', done => {
    request.post('http://localhost:3000', (err, res, body) => {
        JSON.parse(body) // <-- Parsing the body each time
        done();
    })
});

javascript express middleware chai

Answer №1

It seems like you are utilizing the Request library. If I've interpreted your query correctly, you aim for request to automatically interpret your response body using JSON.parse.

You can find instructions on how to achieve this at https://github.com/request/request#requestoptions-callback

json - sets body to JSON representation of value and includes Content-type: application/json header. It also parses the response body as JSON.

Your code snippet should resemble something along these lines:

request.post({url: 'http://localhost:3000', json: true}, (err, res, body) => {
    console.log(res)
    console.log(body)
})

While untested, this is my understanding based on the documentation.
