Max*_*ax 1 redis node.js docker graphql
我正在构建 GraphQL API,并且想对某些解析器进行速率限制。为此,我使用此速率限制器: https: //github.com/teamplanes/graphql-rate-limit
这就是我的实现方式:
import { createRateLimitRule, RedisStore } from 'graphql-rate-limit';
import redis from 'redis'
const rateLimit = createRateLimitRule({
identifyContext: (ctx) => ctx.req.ip,
formatError: () => `Hey there, you are doing way too much`,
store: new RedisStore(redis.createClient(6379, 'redis'))
});

但是当我运行时,docker-compose up我的 NodeJS 应用程序出现此错误:
TypeError: Cannot read property 'createClient' of undefined
我的 PostgreSQL 数据库和 NodeJS 应用程序都正常启动。
这是我的 docker-compose 文件:

还有我的 NodeJS 文件的 Dockerfile:

另外,当我删除 Redis 时,一切正常。所以请帮助我。
它说redisvar 未定义。您可能需要:
import * as redis from 'redis'

或者
const redis = require('redis')

并确保您已安装该软件包:
