TypeError: redis.addCommand is not a function

[Muntzer]

Hi,

I get this errror:

TypeError: redis.addCommand is not a function
at D:\RedisPoc\node_modules\redis-rejson\index.js:5:11

With:

Redis 5.0.0
"redis": "^2.8.0",
"redis-commands": "^1.4.0",
"redis-rejson": "^1.0.0"
npm 6.4.1

How I can resolve it ?

Can you post your code?

Hi Kyle, I have been investigated it. With the code below var redis = require('redis'); var rejson = require('redis-rejson'); var redisClient = redis.createClient({ host: "192.168.99.100", port: 32768 }); redisClient.on("error", function (err) { console.log("Error RedisClient" + err); }); redisClient.on('connect', function() { console.log('RedisClient connected'); }); rejson(redisClient) module.exports = {redisClient} I receive this error: TypeError: redis.addCommand is not a function at D:\RedisPoc\node_modules\redis-rejson\index.js:5:11 at Array.forEach (<anonymous>) at addReJSONModule (D:\RedisPoc\node_modules\redis-rejson\index.js:4:8) at Object.<anonymous> (D:\RedisPoc\config\redis.js:18:1) at Module._compile (internal/modules/cjs/loader.js:702:30) at Object.Module._extensions..js (internal/modules/cjs/loader.js:713:10) at Module.load (internal/modules/cjs/loader.js:612:32) at tryModuleLoad (internal/modules/cjs/loader.js:551:12) at Function.Module._load (internal/modules/cjs/loader.js:543:3) at Module.require (internal/modules/cjs/loader.js:650:17) But with this code, don't appear the error: var redis = require('redis'); var rejson = require('redis-rejson'); rejson(redis) var redisClient = redis.createClient({ host: "192.168.99.100", port: 32768 }); redisClient.on("error", function (err) { console.log("Error RedisClient" + err); }); redisClient.on('connect', function() { console.log('RedisClient connected'); }); module.exports = {redisClient} But, how I can use rejson with the redis client? Like this redisClient. json_set( ? Thanks for your help Javier, El lun., 22 oct. 2018 a las 18:07, Kyle J. Davis (<notifications@github.com>) escribió:

same problem

`
const redis = require('redis');
const rejson = require('redis-rejson');

rejson(redis);

const client = redis.createClient();
client.json_set('order', '{ "name": "Apple", "description": "grey phone" }', redis.print);

`

@Muntzer Your second example is correct. You must run rejson(redis) before creating your client. You would then run the ReJSON commands as normal as methods in the client object.

I'm updating the README with more example code to clarify this.

@Slooo Your problem doesn't actually sound the same as @Muntzer. Open a new issue please.

@stockholmux , thanks for your help.
