原作者: [db:作者] 来自: [db:来源] 收藏 邀请

本文整理汇总了TypeScript中ts-invariant.invariant的典型用法代码示例。如果您正苦于以下问题:TypeScript invariant类的具体用法?TypeScript invariant怎么用?TypeScript invariant使用的例子?那么恭喜您, 这里精选的类代码示例或许可以为您提供帮助。



在下文中一共展示了invariant类的5个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的TypeScript代码示例。

示例1: match

  public match(
    idValue: IdValue,
    typeCondition: string,
    context: ReadStoreContext,
  ): boolean | 'heuristic' {
    const obj = context.store.get(idValue.id);

    if (!obj) {
      // https://github.com/apollographql/apollo-client/pull/3507
      return idValue.id === 'ROOT_QUERY';
    }

    if (!obj.__typename) {
      if (shouldWarn()) {
        invariant.warn(`You're using fragments in your queries, but either don't have the addTypename:
  true option set in Apollo Client, or you are trying to write a fragment to the store without the __typename.
   Please turn on the addTypename option and include __typename when writing fragments so that Apollo Client
   can accurately match fragments.`);
        invariant.warn(
          'Could not find __typename on Fragment ',
          typeCondition,
          obj,
        );
        invariant.warn(
          `DEPRECATION WARNING: using fragments without __typename is unsupported behavior ` +
            `and will be removed in future versions of Apollo client. You should fix this and set addTypename to true now.`,
        );
      }

      return 'heuristic';
    }

    if (obj.__typename === typeCondition) {
      return true;
    }

    // XXX here we reach an issue - we don't know if this fragment should match or not. It's either:
    // 1. A fragment on a non-matching concrete type or interface or union
    // 2. A fragment on a matching interface or union
    // If it's 1, we don't want to return anything, if it's 2 we want to match. We can't tell the
    // difference, so we warn the user, but still try to match it (backcompat).
    if (shouldWarn()) {
      invariant.error(
        'You are using the simple (heuristic) fragment matcher, but your ' +
          'queries contain union or interface types. Apollo Client will not be ' +
          'able to accurately map fragments. To make this error go away, use ' +
          'the `IntrospectionFragmentMatcher` as described in the docs: ' +
          'https://www.apollographql.com/docs/react/advanced/fragments.html#fragment-matcher',
      );
    }

    return 'heuristic';

       return document;
     }
     invariant.warn(
       'Found @client directives in a query but no ApolloClient resolvers ' +
       'were specified. This means ApolloClient local resolver handling ' +
       'has been disabled, and @client directives will be passed through ' +
       'to your link chain.',
