There are two current versions of this application. One deployed through Vercel which can be found here
The other version can be found in the directory titled node-nlp-api which can be run locally as an API on your local machine. Most tools associated with this project are written in Nodejs or bash.

The script test will use text examples from lockdown.txt

| Factor | Implementation Strategy |
|---|---|
| Codebase | Gitlab |
| Dependencies | npm & custom shell scripting & env for dependency isolation |
| Config | Store keys in .env file |
| Backing services | Twitter API & Google Translate API, no file-based io. Investigating reload module at runtime |
| Build, release, run | Use npm build system and GitLab CI/CD |
| Processes | Shell script kicks off 2 processes: static server and API endpoint |
| Port binding | All ports are defined in .env and added at build time |
| Concurreny | Define a shell script to start and stop processes via GitLab CI/CD |
| Disposability | Handle SIGTERM and possibly handle events with a task queue. |
| Dev/prod parity | No database, 2 branches: dev and master, daily merges, smaill team, dev tools all Unix |
| Logs | All output to stdout, aggregated by process management script |
| Admin processes | Support a REPL, support remote shell commands, separate admin dir |
