CockroachDB and Docker Compose

This is the first in a series of tutorials on CockroachDB and Docker Compose

• Information on CockroachDB can be found here.
• Information on Docker Compose can be found here

1. Install Docker Desktop

Because we already have an official CockroachDB docker image, we will use that in our docker-compose.yml file. We recommend you use one of the current tags instead of latest.

usage

go build: compiles the packages named by the import paths, along with their dependencies, the binary does not end up in $GOPATH/bin it gets created in the dirs

go build [-o output] [build flags] [packages]

If the [packages] are a list of .go files, build treats them as a list of source files specifying a single package.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

var Article = require('../../../models/article');

Those suck for maintenance and they're ugly.

Possible solutions

Synopsis

At the top of the file there should be a short introduction and/ or overview that explains what the project is. This description should match descriptions added for package managers (Gemspec, package.json, etc.)

Code Example

Show what the library does as concisely as possible, developers should be able to figure out how your project solves their problem by looking at the code example. Make sure the API you are showing off is obvious, and that your code is short and concise.
