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

LastaFlute Cast

LastaFlute Repository (with License, Fork info)

The source codes are in Github. You can also see the license and fork information.

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);
}
