setJsonContent

import { setJsonContent } from '@seontechnologies/pactjs-utils'
import type { JsonContentInput } from '@seontechnologies/pactjs-utils'

type JsonContentInput = {
  body?: unknown
  headers?: TemplateHeaders
  query?: TemplateQuery
}

const setJsonContent = (input: JsonContentInput) => (builder) => void

A curried helper for Pact V4 HTTP builder callbacks that removes repetitive inline lambdas around builder.query(...), builder.headers(...), and builder.jsonBody(...).

It is intentionally builder-agnostic:

• On request builders (.withRequest(...)), query, headers, and body are applied
• On response builders (.willRespondWith(...)), headers and body are applied, and query is ignored

Examples

// Full example: https://github.com/seontechnologies/pactjs-utils/blob/main/pact/http/consumer/movies-read.pacttest.ts
import { MatchersV3 } from '@pact-foundation/pact'
import { setJsonContent } from '@seontechnologies/pactjs-utils'

const { like, string, integer } = MatchersV3

await pact
  .addInteraction()
  .uponReceiving('a request to get a movie by name')
  .withRequest(
    'GET',
    '/movies',
    setJsonContent({
      query: { name: 'Inception' }
    })
  )
  .willRespondWith(
    200,
    setJsonContent({
      body: {
        status: 200,
        data: {
          id: integer(1),
          name: string('Inception'),
          year: integer(2010)
        }
      }
    })
  )

You can also use headers for either side:

setJsonContent({
  headers: { 'x-correlation-id': 'pact-test' },
  body: { ok: true }
})
