(OLD_mongodb)how-to-run.txt

=== QUICK RUN ===
0. run “npm install —-save” 
1. run go to /client and “npm start” (Start server)
2. run go to /server and “npm start” (Start server)
3. find where mongodb’s folder is (originally in /alexwong/mongodb).
4. run ““./mongod —dbpath ‘../data/db’” (Start MongoDB server)
5. run “./mongo” (Start MongoDB shell client)
6. go to /client and run "npm compodoc"

=== BASIC COMPONENTS ===
angular: front-end (client-side), SPA

nodeJs: server-side
express: framework of nodeJs to handle routes

mongodb: we will use mongoose to provide concept of schema and model (so we don't need to define it ourselves)
mongoose: framework around mongodb to add features such as schemas & models, validation, intuitive database operations (so we don’t need to code them ourselves); installed via nom install —save mongoose

compodoc: create documentation

=== SETTING UP WEBSITE & SERVER (seed project) ===
UI: run ‘npm build’; it will compile a build of our UI and continuously watch for updates and compile accordingly (this does NOT host the UI, UI is hosted by server)
Server: run ‘npm start’.

=== SETTING UP MONGODB ===
1. Download mongodb (from website)
2. navigate to download folder /bin.
3. You can now move this bin folder to anywhere in your machine.
4. On the mongodb website, go to quick start and follow the steps.
5. In monogodb folder, create path: mkdir -p /data/db
6. Then, from /bin folder, run the mongodb server: and link that /data/db folder with your run command: “./mongod —dbpath ‘../data/db’”
7. In another terminal, run mongodb shell client (usually node js will do this for us): go to /bin and run: “./mongo”

=== SOME MONGODB NOTES ===
On terminal with ./mongo, you  can run commands:

use <db> : switch (new) db.

db.<(new)Collection>.insert({<key>.<value>}) : insert data to new collection/table with data as json representation of key and value.

show dbs : print list of all databases on the server
show databases: print list of all available databases on the server.
show collections : show all the collections/table within() a db

db.<collection>.find() : print out the items in collections (can do query)
db.<collection>.deleteMany({“<key>”: “<value>”})
db.<collection>.remove({<key>: "<value>"})    : delete an item from collection; need to provide at least one key and value.
