QUESTION
I have a code to update or create new users in my system. It works with a forEach function, and works well. However, I want to take advantage of Node.js and execute several updates/creations at the same time. I have tried to create an array of promises, but I think I am building the promises wrong. This is the code that works fine:
...ANSWER
Answered 2021-Feb-10 at 17:49First, move the code flow that deals with each individual
user
value into its own separateasync
function.- Because of how
async
functions actually work (as eachasync function
marks the boundary of each async state-machine) it isn't really feasible to do concurrent-async work inside afor
statement.
- Because of how
Invoke that function from within the
for
loop.Always prefer
===
over==
.Use TypeScript. Using
async
JavaScript without TypeScript is a world of pain because you need to keep track of which functions returnPromise
vs. those that don't, as well as correctly unwrappingPromise
objects.Always, wherever possible, have your own
try/catch
statement that wraps the entire body of anasync
function, otherwise you'll have to deal with inconsistencies with how different JS engines and JS code handles thrown exceptions and objects.

QUESTION
I am currently working on an angular app using Rest API (Express, Nodejs) and Postgresql. Everything worked well when hosted on my local machine. After testing, I moved the images to Ubuntu server so the app can be hosted on an external port. I am able to access the angular frontend using the https://server-external-ip:80 but when trying to login, Nginx is not connecting to NodeApi. Here is my docker-compose file:
...ANSWER
Answered 2020-Aug-22 at 01:51I think you should use the docker-compose
service as a DNS
. It seems you've several docker hosts/ports available, there are the following in your docker-compose structure:
- db:5432
- http://backend:3000
- http://myapp
Make sure to use db
as POSTGRES_DB
in the environment part for backend
service.
Take a look to my repo, I think is the best way to learn how a similar project works and how to build several apps with nginx
, you also can check my docker-compose.yml
, it uses several services and are proxied using nginx
and are worked together.
On this link you’ll find a nginx/default.conf
file and it contains several nginx
upstream configuration please take a look at how I used docker-compose service references there as hosts
.
Inside the client/ directory, I also have another nginx
as a web server of a react.js project.
On server/ directory, it has a Node.js API, It connects to Redis and Postgres SQL database also built from docker-compose.yml.
If you need set or redirect traffic to /api you can use some ngnix
config like this
I think this use case can be useful for you and other users!
