Node.js – No living connections Error while Elasticsearch connections in nodejs

elasticsearchnode.js

I am having this problem while connecting the elasticsearch connections.


var elasticsearch = require('elasticsearch');
var client = new elasticsearch.Client({ host: 'localhost:9200',
                                       log: 'trace'});

I understand this question is quite old but I wanted to share how you can solve this problem.

If you are locally using elasticsearch

First thing you must do is running elasticsearch on your machine.

Error: Request error, retrying -- connect ECONNREFUSED 127.0.0.1:9200

Because above message indicates that you're not running elasticsearch locally.

So, visit the link and follow the insturction.

Docker environment

It gets much trickier here.

First, follow the instruction here.

And in case you're using node.js elasticsearch client, you have to specify elasticsearch host as 172.24.0.1.

If you use container_name or private IP of container in docker-compose.yml, it won't work.

Node.js – How to update NodeJS and NPM to the next versions

See the docs for the update command:

npm update [-g] [<pkg>...]

This command will update all the packages listed to the latest version (specified by the tag config), respecting semver.

Additionally, see the documentation on Node.js and NPM installation and Upgrading NPM.

The following original answer is from the old FAQ that no longer exists, but should work for Linux and Mac:

How do I update npm?
npm install -g npm
Please note that this command will remove your current version of npm. Make sure to use sudo npm install -g npm if on a Mac.

You can also update all outdated local packages by doing npm update without any arguments, or global packages by doing npm update -g.

Occasionally, the version of npm will progress such that the current version cannot be properly installed with the version that you have installed already. (Consider, if there is ever a bug in the update command.) In those cases, you can do this:
curl https://www.npmjs.com/install.sh | sh

To update Node.js itself, I recommend you use nvm, the Node Version Manager.
