伺服器安裝實施
GraphQL.js
GraphQL.js 是 GraphQL 的 JavaScript 參考實現。你可以通過 npm 安裝它：
- 如果你還沒有在專案中初始化 npm：
npm init - 從 npm：
npm install --save graphql安裝 GraphQL.js
示例伺服器
var { graphql, buildSchema } = require('graphql');
// Construct a schema, using GraphQL schema language
var schema = buildSchema(`
type Query {
hello: String
}
`);
// The root provides a resolver function for each API endpoint
var root = {
hello: () => {
return 'Hello world!';
},
};
// Run the GraphQL query '{ hello }' and print out the response
graphql(schema, '{ hello }', root).then((response) => {
console.log(response);
});
