Eusda Tutorial

Install it with

``
npm i -g eusda
`

The first time it will ask you some questions to
configure the database.

Here is an example of how to configure it locally with a default file:

`
[.../tfg-kathrina-arrocha-umpierrez/deploy(master)]$ eusda
The directory 'files' was created.
The directory 'zip' was created.
The directory 'unzip' was created.
The directory 'json' was created.
███████╗██╗ ██╗███████╗██████╗ █████╗
██╔════╝██║ ██║██╔════╝██╔══██╗██╔══██╗
█████╗ ██║ ██║███████╗██║ ██║███████║
██╔══╝ ██║ ██║╚════██║██║ ██║██╔══██║
███████╗╚██████╔╝███████║██████╔╝██║ ██║
╚══════╝ ╚═════╝ ╚══════╝╚═════╝ ╚═╝ ╚═╝

? Do you want to use a default configuration file? Yes.
? Where will your config file be? I want to use this directory.
New directory: /Volumes/2020/TFG/tfg-kathrina-arrocha-umpierrez/deploy/config/eusda
New file: /Volumes/2020/TFG/tfg-kathrina-arrocha-umpierrez/deploy/config/eusda/default.json
`

this will create the following tree:

`
[.../tfg-kathrina-arrocha-umpierrez/deploy(master)]$ tree
.
├── config
| └── eusda
│   └── default.json
└── files
├── json
├── unzip
└── zip

6 directories, 1 file
`

The command eusda config shows the contents of the configuration file:

`
[.../tfg-kathrina-arrocha-umpierrez/deploy(master)]$ eusda config
eusda 2.0.6

The configuration used is:

Config {
db:
{ host: '127.0.0.1',
port: 27017,
name: 'eusda',
collectionUSDA: 'food' },
usda:
{ urls:
{ default: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/SR/sr28/dnload/sr28abxl.zip',
sr28: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/SR/sr28/dnload/sr28abxl.zip',
sr27: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/sr27/dnload/sr27abxl.zip',
sr26: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/sr26/dnload/sr26abxl.zip',
sr25: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/sr25/dnload/sr25abxl.zip',
sr24: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/sr24/dnload/sr24abxl.zip',

sr22: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/sr22/dnload/sr22abxl.zip',
sr21: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/sr21/dnload/sr21abxl.zip',
sr20: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/sr20/sr20abxl.zip',
sr19: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/sr19/sr19abxl.zip',
sr18: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/sr18/sr18abxl.zip',
sr17: 'https://www.ars.usda.gov/ARSUserFiles/80400535/DATA/sr17/sr17abxl.zip' } },
files: { zip: 'data.zip', json: 'usda.json', dish: 'dishes.json' },
directories_path:
{ zip: './files/zip/',
unzip: './files/unzip/',
json: './files/json/'
}
}
`

With the command download you can download the default version:

`
[.../tfg-kathrina-arrocha-umpierrez/deploy(master)]$ eusda download
eusda 2.0.6

Downloading from USDA, using version sr28
You can choose another version in this URL:
https://www.ars.usda.gov/northeast-area/beltsville-md-bhnrc/beltsville-human-nutrition-research-center/methods-and-application-of-food-composition-laboratory/mafcl-site-pages/sr11-sr28/
Then, you should change it in our configuration file: ./config/default.json

Extracted files
Converting excel file to json...
Process successfully completed
New json file created in ./files/json/
`

The new tree structure is:

`
[.../tfg-kathrina-arrocha-umpierrez/deploy(master)]$ tree -s
.
├── [ 4096] config
│ └── [ 4096] eusda
│ └── [ 1559] default.json
└── [ 4096] files
├── [ 4096] json
│ └── [ 11787549] usda.json
├── [ 4096] unzip

│ └── [ 653211] sr28_doc.pdf
└── [ 4096] zip
└── [ 3050195] data.zip

6 directories, 5 files
`

Observe the size of the file files/json/usda.json: it contains the whole data base in JSON format. For instance, to get the 2nd item description we can use jq:

`
[.../tfg-kathrina-arrocha-umpierrez/deploy(master)]$ jq .[1].shrt_desc files/json/usda.json
"BUTTER,WHIPPED,W/ SALT"
`

Be sure MongoDB is installed and mongod is running. If not,
install it,
confifure it
and run it:

`
[.../tfg-kathrina-arrocha-umpierrez/deploy(master)]$ mkdir mongo-database
[.../tfg-kathrina-arrocha-umpierrez/deploy(master)]$ cd mongo-database/
[.../deploy/mongo-database(master)]$ mongod --dbpath .
2020-06-04T11:33:33.492+0100 I CONTROL [main] Automatically disabling TLS 1.0, to force-enable TLS 1.0 specify --sslDisabledProtocols 'none'
2020-06-04T11:33:33.522+0100 I CONTROL [initandlisten] MongoDB starting : pid=9774 port=27017 dbpath=. 64-bit host=sanclemente-2.local
...
`

This commands start mongod in the directory mongo-database:

`
[.../tfg-kathrina-arrocha-umpierrez/deploy(master)]$ tree mongo-database/
mongo-database/
├── WiredTiger
├── WiredTiger.lock
├── WiredTiger....
├── _mdb_catalog.wt
├── collection-.....wt
├── diagnostic.data
│   ├── metrics.2020-06-04T10-33-42Z-00000
│   └── metrics.interim
├── index-6--5.....wt
├── journal
│   └── WiredTigerPreplog....
├── mongod.lock
├── sizeStorer.wt
└── storage.bson

2 directories, 21 files
`

Now we can upload the json file inside the mongo database with

`
.../tfg-kathrina-arrocha-umpierrez/deploy(master)]$ eusda insert
eusda 2.0.6
Inserting data in the collection: food
Data was successfully inserted
`


Now, the database and collection with the data should have been created.
exit. To check it, you can do this:


`
$ mongo
> show dbs
admin 0.000GB
config 0.000GB
eusda 0.003GB
local 0.000GB
> use eusda
switched to db eusda
> show collections
food
