A web interface to an NMDC/ADC hub.

Tags: nmdc

Chat in real-time on your NMDC/ADC hub using a web browser.


This project forks and deprecates my earlier dcwebui2 project since Go seems to use less memory than node.

This project supercedes dcwebui, flexdc, and dcwebui2.

### Upgrading from dcwebui2

• The configuration file content is identical between nmdc-webfrontend 1.0.0 and dcwebui2 1.3.0, but please now ensure it's valid JSON instead of arbitrary javascript. This means no assignment, use double-quoted strings, and no comments.
• Future changes to the configuration file since nmdc-webfrontend 1.0.0 are backward compatible (see the changelog for more details).


1. Install Go (>= 1.11), Node.js, NPM, and 7-Zip (p7zip-full on Debian)
2. Download the source code
- git clone ; or
- go get ; or
- download and extract a source archive
3. Install dependencies: sudo make deps
4. Build: make
5. Optional: Set web.external_webroot: true in the config file for unminified development
