Relationship to other projects

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
