ngx-翻译数据库中的值？

Question

我正在使用ngx-translate模块制作一个angular2应用

该服务使用.json文档来查找翻译

首先...我注意到本地json文档的路由是“ / src / assets / i18n /”，就像下一张图片一样：

因此，翻译服务使用默认语言翻译不同文本

这是我的app.component.ts的工作方式：

    ... 4 more

因此该服务使用“ en.json”，“ es.json”和“ fr.json”来匹配翻译。

所以我的问题是

如何避免使用“ json”文档并使文本与数据库中的文本匹配？

因此不必重新构建客户端即可获得新的翻译更新，只需将其添加到数据库并无需重新构建即可自动翻译

Ngx-translate有一个setTranslation方法，该方法接受Lang键和JSON对象-您可以从任何地方（例如数据库）加载JSON对象，并使用此对象进行设置

setTranslation(lang: string, translations: Object, shouldMerge: boolean = false): Manually sets an object of translations for a given language, set shouldMerge to true if you want to append the translations instead of replacing them
