LastaFlute
What is LastaFlute?
Typesafe Web Framework for LeAn STArtup with DBFlute and Java8
Rhythm & Speed Programming
Startup has repeated trial & error so light-weight development environment is needed.
- Hot Deploy
- fix action and immediately confirm it without reboot
- Lightening Boot
- fast reboot even if it needs to reboot
.........................................................rhythmical thinking is speed
Adaptable-to-Change Programming
Startup has repeated requirement change so safety mechanism is needed.
- Hard Typesafe
- typesafe action implementation and condition-bean
- Aggressive DB Change
- DBFlute on Full Power, and FreeGen
- Crazy Logging
- looks-like-good log
.........................................................safety is speed
Naturally-be-so Programming
Startup has also repeated human resource change so power of natural is needed.
- Convention Mapping
- URL = class + method: searchable class from URL
- Less Choice
- remove unneeded option, uniform as possible
- Default Libraries
- from configuration to mail library
.........................................................unshaken is speed

How to implement
Java8-on-parade Action.
Mapping Convention
- Request URL
- Action class + Execute method
Package Convention
- Application Package
- [your domain].app e.g. org.docksidestage.app
- Web Package
- [Application Root].web e.g. org.docksidestage.app.web
- Action's Package
- *you can use Action's prefix package
Example for HTML response style
e.g. Action for URL '/product/list/3' as HTML response @Java
@Execute
public HtmlResponse index(OptionalThing<Integer> pageNumber
, ProductSearchForm form) {
validate(form, messages -> (), () -> {
return asHtml(path_Product_ProductListJsp);
});
PagingResultBean<Product> page = productBhv.selectPage(cb -> {
cb.setupSelect_ProductStatus();
cb.query().setProductName_LikeSearch(form.productName, op -> op.likeContain());
cb.query().addOrderBy_ProductName_Asc();
cb.paging(getPagingPageSize(), pageNumber.orElse(1));
});
List<ProductRowBean> beans = page.mappingList(product -> {
return mappingToBean(product);
});
return asHtml(path_Product_ProductListJsp).renderWith(data -> {
data.register("beans", beans);
registerPagingNavi(data, page, form);
});
}
Example for JSON response style
e.g. Action for URL '/product/list/3' as JSON response @Java
@Execute
public JsonResponse<SearchPagingBean<ProductRowBean>> index(
OptionalThing<Integer> pageNumber
, ProductSearchBody body) {
validate(body, messages -> {});
ListResultBean<Product> page = productBhv.selectPage(cb -> {
cb.setupSelect_ProductStatus();
cb.query().setProductName_LikeSearch(form.productName, op -> op.likeContain());
cb.query().addOrderBy_ProductName_Asc();
cb.paging(getPagingPageSize(), pageNumber.orElse(1));
});
SearchPagingBean<ProductRowBean> bean = createPagingBean(page);
return asJson(bean);
}
