# go-web-app-template
# Holiday api
Basic template for creating go applications
Simple api used for tracking holidays
Includes:
* dotenv
* pq
* sqlx
* chi
* google.uuid
## Endpoints
To start using make sure to setup either environment variables listed
below, or create .env file and copy variables below
Fetching is done via `GET /api/v1/holidays` endpoint
That endpoint accepts a list of required and optional parameters
### Required parameters
`country`
- determines for which country holidays are fetched, uses ISO 3166-1 Alpha-2 codes [more info here](https://en.wikipedia.org/wiki/ISO_3166-1)
- eg. `country=US`
### Optional parameters
`year`
- returns only holidays for given year
- eg. `year=2023`
- only used if no more important parameters are defined
`date`
- returns only holidays for given date
- date must be formatted in ISO 8601 format [more info here](https://www.iso.org/iso-8601-date-and-time-format.html)
- eg. `date=2021-12-25`
- if defined year and rangeStart|rangeEnd parameters are ignored
`rangeStart|rangeEnd`
- returns holidays in given range with both ends being inclusive
- if either limit isn't defined it is assumed to be up to or all from given limit (if rangeStart isn't defined all holidays before rangeEnd are returned and vice-verse)
- dates must be formatted in ISO 8601 format [more info here](https://www.iso.org/iso-8601-date-and-time-format.html)
- eg. `rangeStart=2021-12-25&rangeEnd=2023-01-23`, `rangeStart=2023-01-20`
- if defined year parameter is ignored
`stateHoliday`
- if set true only holidays that are tagged as state holidays are returned, similar for if set false, if not set all holidays are returned
- eg. `stateHoliday=true`, `stateHoliday=false`
`religiousHoliday`
- if set true only holidays that are tagged as religious holidays are returned, similar for if set false, if not set all holidays are returned
- eg. `religiousHoliday=true`, `religiousHoliday=false`
#### Paging
`pageSize`
- returns at most pageSize number of holidays
- eg. `pageSize=20`
- only applied if page is defined as well, by default set to 20
`page`
- returns nth page of holidays, paging starts at 0
- eg. `page=0`
## Response
By default, responses are returned as a json array
```
PSQL_HOST=localhost
PSQL_PORT=5432
PSQL_USER=template
PSQL_PASSWORD=templatePassword
PSQL_DB=template
[{
id: string;
date: string(ISO 8601);
name: string;
description: string;
isStateHoliday: boolean;
isReligiousHoliday: boolean;
},...]
```
eg.
```
[{
"id": "74a2a769-abf2-45d4-bdc4-442bbcc89138",
"date": "2023-12-25",
"name": "Christmas",
"description": "TBD",
"isStateHoliday": true,
"isReligiousHoliday": true
}]
```
Also, database is required for template to start, so you can start it with `docker compose up -d`
But can be returned as XML or CSV by setting appropriate `Accept` header (application/xml, text/xml or text/csv)
XML Response
```
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<Holidays>
<Holiday id="74a2a769-abf2-45d4-bdc4-442bbcc89138" date="2023-12-25" isReligious="true" isState="true">
<name>Christmas</name>
<description>TBD</description>
</Holiday>
</Holidays>
```
CSV Response
```
id,date,name,description,is_state_holiday,is_religious_holiday
74a2a769-abf2-45d4-bdc4-442bbcc89138,2023-12-25,Christmas,TBD,true,true
```
