javascript - [GraphQL 错误] : Message: Unknown fragment

Question

我想使用一些片段:

import {gql} from "apollo-boost";
import "../fragments/cardFragments.graphql"

export const ADD_CARD = gql`
    mutation AddCard {
        createCard(input: {
            private: true,
            section: "school",
            createdBy: "api/users/1"
        }) {
            card {
                ...CardFields
            }
        }
    }
`;

export default {ADD_CARD}

cardFragments.graphql:

fragment CardFields on card {
    id
    private
    section
    createdBy {
        id
    }
}

在控制台内我收到错误:

[GraphQL error]: Message: Unknown fragment "CardFields"., Location: [object Object], Path: undefined

我忘了什么吗？

编辑:

为了让 graphql 片段工作，我需要使用 webpack 加载它: Apollo docs

我用 Webpack Encore 做了这个:

.addLoader({
    test: /\.(graphql|gql)$/,
    exclude: /node_modules/,
    loader: 'graphql-tag/loader',
});

module.exports = Encore.getWebpackConfig();

在我这样做之前 - 我收到了 Webpack Encore 内部不可加载的 .graphql 扩展的错误.

关于使用 Webpack Encore 创建 cutsom 加载程序有什么我看不到的吗？ ?

你应该 import { CardFields } from "../fragments/cardFragments.js"然后在你的突变中使用这个片段，如下所示:

import {gql} from "apollo-boost";
import { CARD_FEILDS } from "../fragments/cardFragments.js"

export const ADD_CARD = gql`
    mutation AddCard {
        createCard(input: {
            private: true,
            section: "school",
            createdBy: "api/users/1"
        }) {
            card {
                ...CardFields
            }
        }
    }
    ${CARD_FEILDS}
`;

export default {ADD_CARD}

在 cardFragments.js 中:

import {gql} from "apollo-boost"
export const CARD_FEILDS = gql `
  fragment CardFields on card {
    id
    private
    section
    createdBy {
        id
    }
  }
`
