File Metadata Micro-service

An app that, on file upload, returns a JSON response which includes a 'name', 'size', 'date', and 'file'.

Getting Started

Create your own server. I used mLab.com. Create a user on that server.

Create your own .env file in the root directory with a DB_URI which links to your server. Here is an example:

PORT=8000
HOST=127.0.0.1
DB_URI=mongodb://<dbuser>:<dbpassword>@ds125588.mlab.com:25588/answart-file-metadata-ms
DB_USER=<dbuser>
DB_USER_PASS=<dbpassword>
SECRET=my-super-secret

Install dependencies then launch app @ localhost:8000.

$ npm install
$ npm start
