角2 websql键入 [英] angular 2 websql typings
问题描述
我正在使用angular 4用电子方式编写应用程序.我需要一个数据库,并且想使用websql,但是找不到导入websql类型的方法.
I am writing an app in electron using angular 4. I need a database and want to use websql but I cannot find a way to import websql typings.
我添加了@ types/websql.在我的IDE中,当我这样做时没有编译错误:
I added @types/websql. In my IDE, there is no compil error when i do :
const db: Database = window.openDatabase('foo', '1.0', 'foo', 2 * 1024 * 1024);
但是ng serve
给了我:
Property 'openDatabase' does not exist on type 'Window'
我没有任何特定于@types/websql
的导入.由于它不是模块,所以我不知道如何导入它.
I do not have any import specific to @types/websql
. As it is not a module, I don't know how to import it.
有人对我如何导入它有任何想法吗?
Does anyone have any idea on how I can import this ?
推荐答案
好,我找到了解决方法.
Ok, I found the solution.
ng-cli生成一个tsconfig.app.json,其属性types
设置为[].
如果我正确理解tsc doc,它将阻止编译器使用typeRoots
属性.
ng-cli generate a tsconfig.app.json with a property types
set to [].
If I understand tsc doc correctly, it prevents the compiler to use the typeRoots
property.
只需删除此属性,即可编译我的代码.
By simply removing this property, my code compile.
