The unmet need

We wanted a lightweight ElasticSearch data browser to include within the Appbase.io dashboard. We started out with evaluating existing browsers to see if we could repurpose them for our needs.

We were primarily looking for -

1. Client-side rendering: Introducing either server-side code or database coupling would introduce performance hits and make hosting more prone to more failure scenarios; we felt strongly about client-side rendering.
2. Déjà vu: While a polished UI is starting to become the norm in modern apps, we found that some data browsers have yet to match up in this regards.

We evaluated the most popular data browsers and found them lacking with either their client-side rendering capabilities or their UI / Ux sensibilities.

the best way (I've found) to completely uninstall node + npm is to do the following:

go to /usr/local/lib and delete any node and node_modules
go to /usr/local/include and delete any node and node_modules directory
if you installed with brew install node, then run brew uninstall node in your terminal
check your Home directory for any local or lib or include folders, and delete any node or node_modules from there
go to /usr/local/bin and delete any node executable
You may need to do the additional instructions as well:

sudo rm /usr/local/bin/npm

1. Open Terminal
2. cd to your Xcode project
3. Execute the following when inside your target project:

find . -name "*.swift" -print0 | xargs -0 wc -l
