О чём код?
#!/usr/bin/env node // Some copypasta that does an exhaustive introspection query on some graphql // server and outputs a pretty-printed schema. // // Install dependencies: // // $ npm install -g axios graphql // // Usage, e.g.: // // $ NODE_PATH=$(npm root --quiet -g) utils/dump-remote-schema.js http://localhost:8088/v1/graphql // // TODO whatever if there's a more appropriate way to install dependencies such // that this script can be called from anywhere, and without littering // everything with node_modules directories. const { introspectionQuery, buildClientSchema, printSchema } = require('graphql'); const axios = require('axios'); if (process.argv.length != 3){ console.log("Supply the graphql server URL as the only argument on the command line"); process.exit(1); } axios({ url: process.argv[2], method: 'post', headers: { 'Content-Type': 'application/json' }, data: {operationName: "IntrospectionQuery", query: introspectionQuery}, }).then(({data}) => { console.log(data); if (data.errors) { console.log(data.errors); console.log("\n ^^^^^^^^^^^^^^^ OOPS GOT SOME ERRORS FROM THE SERVER ^^^^^^^^^^^^^^^\n\n"); // proceed anyway I guess } const schema = buildClientSchema(data.data); console.log(printSchema(schema)); }).catch(error => { console.log(error); console.log("\n ^^^^^^^^^^^^^^^ OOPS GOT SOME ERRORS ^^^^^^^^^^^^^^^\n\n"); });
