Graphql 如何将本地@client模式扩展添加到apollo codegen
我正在使用,它向查询根添加了一些字段,我提供了一个Graphql 如何将本地@client模式扩展添加到apollo codegen,graphql,apollo,react-apollo,flow,apollo-client,Graphql,Apollo,React Apollo,Flow,Apollo Client,我正在使用,它向查询根添加了一些字段,我提供了一个typeDef,它看起来像这样: extend type Query { foo: String } 我也在用。但是,它不应用扩展,并返回一个错误: .../src/components/Foo/Foo.js: Cannot query field "foo" on type "Query". 当遇到对扩展字段的查询时: query FooQuery { foo @client } 所以我的问题是:我如何告诉apollo c
typeDef
,它看起来像这样:
extend type Query {
foo: String
}
我也在用。但是,它不应用扩展,并返回一个错误:
.../src/components/Foo/Foo.js: Cannot query field "foo" on type "Query".
当遇到对扩展字段的查询时:
query FooQuery {
foo @client
}
所以我的问题是:我如何告诉apollo codegen有关客户端扩展的信息?好的,根据我们的说法,目前还没有内置的方法。受此启发,我编写了一个快速脚本来合并服务器和客户端架构:
#!/usr/bin/env node
const fs = require("fs");
const path = require("path");
const { introspectionFromSchema } = require("graphql/utilities");
const { makeExecutableSchema } = require("graphql-tools");
const { fileLoader, mergeTypes } = require("merge-graphql-schemas");
// Make sure unhandled errors in async code are propagated correctly
process.on("uncaughtException", error => {
console.error(error);
process.exit(1);
});
process.on("unhandledRejection", error => {
throw error;
});
async function introspectSchema(input, output) {
const schemas = [].concat(...input.map(i => fileLoader(i)));
const typeDefs = mergeTypes(schemas, {
all: true
});
const schema = await makeExecutableSchema({
typeDefs,
resolverValidationOptions: { requireResolversForResolveType: false }
});
const introspection = await introspectionFromSchema(schema);
const json = JSON.stringify(introspection, null, 2);
fs.writeFileSync(output, json);
}
const input = [
path.join(__dirname, "../data/*.graphql"),
path.join(__dirname, "../src/*.graphql")
];
const output = path.join(__dirname, "../src/__generated__/schema.json");
// Generate an introspection JSON format from remote GraphQL server merging
// with any local GraphQL schemas
introspectSchema(input, output, true);
并在运行codegen之前调用它:
node scripts/merge.js && \
apollo-codegen generate src/components/**/*.js \
--schema src/__generated__/schema.json \
--target flow-modern \
--add-typename \
--use-flow-exact-objects false \
--use-flow-read-only-types true
请注意,这并不验证对客户机模式的查询是否使用@client
指令,这将是一流支持的一大优势。但是,这至少会使生成的类型保持工作状态
