如何从next.js 应用程序调用Prismic (CMS) API ？在 next.js 我以前有过：

import React from 'react'
import Link from 'next/link'
import 'isomorphic-fetch'

export default class Index extends React.Component {
  static async getInitialProps () {
    const res = await fetch('https://myAPI_URL')
    const json = await res.json()
    return { cars: json.results }
  }

  render () {
    return (
      <div>
        <p>I can see the data {this.props.cars} </p>
      </div>
    )
  }
}

但我想使用 Prismic 开发工具包作为依赖项，如他们的文档中所述。 

npm install prismic-javascript prismic-dom --save

以及调用 Prismic 的代码：

const Prismic = require('prismic-javascript');

const apiEndpoint = "https://your-repository-name.prismic.io/api/v2";
const apiToken = "this_is_a_fake_token_M1NrQUFDWUE0RYvQnvv70";

Prismic.getApi(apiEndpoint, {accessToken: apiToken}).then(function(api) {
  return api.query(""); // An empty query will return all the documents
}).then(function(response) {
  console.log("Documents: ", response.results);
}, function(err) {
  console.log("Something went wrong: ", err);
});

但是如何让 Prismic API 调用在 getInitialProps 中与 next.js 一起工作？例如：

import React from 'react'
import Link from 'next/link'
import 'isomorphic-fetch'

export default class Index extends React.Component {
  static async getInitialProps () {
    // fetch Prismic API and return the results
  }

  render () {
    return (
      <div>
        <p>Showing data fetched from API here</p>
      </div>
    )
  }
}

您已经准备好所有组件。而不是fetch等待Prismic请求。然后返回结果。

import React from 'react';
import Prismic from 'prismic-javascript';

const apiEndpoint = 'https://project.prismic.io/api/v2';
const apiToken = 'TOKEN';

export default class Index extends React.Component {
  static async getInitialProps({ req, query }) {
    const data = await Prismic.getApi(apiEndpoint, { accessToken: apiToken })
      .then(api => {
        return api.query(''); // An empty query will return all the documents
      })
      .catch(err => console.log(err));

    return { cars: data.results };
  }

  render() {
    return <div>Example car id: {this.props.cars[0].id}</div>;
  }
}
