Library provides Micronaut [Jackson Datetime](https://github.com/GoodforGod/jackson-datetime-configuration) module integration and configuration.

You can read more about [module and its configuration here](https://github.com/GoodforGod/jackson-datetime-configuration).

## Dependency :rocket:

**Gradle**

```groovy

implementation "io.goodforgod:micronaut-jackson-datetime:3.0.0"

```

**Maven**

```xml

    io.goodforgod

    micronaut-jackson-datetime

    3.0.0

```

## Configuration

You can read more about [module configuration in details here](https://github.com/GoodforGod/jackson-datetime-configuration#configuration), below is *application.yaml* configuration example:

```yaml

jackson:

  datetime:

    enabled: true                                                       # Enable DateTime module registration (default true)

    module:

      offset-time-format: HH:mm:ss[.SSS]XXX                             # Set OffsetTime formatter (<- default value)

      offset-date-time-format: uuuu-MM-dd'T'HH:mm:ss[.SSS]XXX           # Set OffsetDateTime formatter (<- default value)

      zoned-date-time-format: uuuu-MM-dd'T'HH:mm:ss[.SSS]XXX['['VV']']  # Set ZonedDateTime formatter (<- default value)

      local-date-time-format: uuuu-MM-dd'T'HH:mm:ss[.SSS]               # Set LocalDateTime formatter (<- default value)

      local-date-format: uuuu-MM-dd                                     # Set LocalDate formatter (<- default value)

      local-time-format: HH:mm:ss[.SSS]XXX                              # Set LocalTime formatter (<- default value)

      year-format: uuuu                                                 # Set Year formatter (<- default value)

      year-month-format: uuuu-MM                                        # Set YearMonth formatter (<- default value)

      month-day-format: MM-dd                                           # Set MonthDay formatter (<- default value)

      force-resolver-strict: true                                       # Forces ResolverStyle#STRICT for all formatters (default - false)

      force-iso-chronology: true                                        # Forces IsoChronology for all formatters (default - false)

```

If you want know more about [Java Date & Time you can read article here](https://goodforgod.dev/posts/2/).

### Hints

For proper Date & Times serialization, you probably don't want to adjust ZoneOffset when deserializing and serializing as longs, then configure as follows:

```yaml

jackson:

  serialization:

    write-dates-as-timestamps: false            # Don't write dates as longs

  deserialization:

    adjust-dates-to-context-time-zone: false    # Don't change ZoneOffset to local

```

### Recommended Configuration

Below is minimal recommended configuration that will be working for most cases.

```yaml

jackson:

  serialization:

    write-dates-as-timestamps: false            # Don't write dates as longs

  deserialization:

    adjust-dates-to-context-time-zone: false    # Don't change ZoneOffset to local

  datetime:

    enabled: true                               # Enables date time module registration

```

## Micronaut Compatability
