Question

我有一个小的代码示例，使用ramda时可以按预期运行，但是我尝试将此代码移植到保护区的尝试失败。

<div id='root'>
  <div class='flex-fill flex-col'>
     <div><h1>main title</h1></div>
     <div class="flex-col">
        <div class='flex-col'>
           <div><h2>subtitle</h2></div>
           <div class="flex-row">
              <div>...left side nav list...</div>
              <div class='flex-col'>
                 <div>...data header...</div>
                 <!--Now Scrolls-->
                 <div class="scrolling-div">
				 ...scrolling data list...<br />
				 ...scrolling data list...<br />
				 ...scrolling data list...<br />
				 ...scrolling data list...<br />
				 </div>
              </div>
           </div>
        </div>
     </div>
  </div>
</div>

问题是ramda版本按预期运行，但避难所版本因该错误而退出，可以有人解释其原因。

const IO = require('fantasy-io');
const S = require('sanctuary');
const R = require('ramda');

const url = 'http://localhost:8010?param1=arg1&param2=arg2';

const io = IO.of(url);

// Works as expected:

const r = R.map(R.split('?'), io);
console.dir(r.unsafePerform());
// -> [ 'http://localhost:8010', 'param1=arg1&param2=arg2' ]

// Fails:    

const s = S.map (S.splitOn('?')) (io);
console.dir(s.unsafePerform());

仅发布了一个Fantasy-io版本：

exports.getCountByBranch = async function (req, res) {
let docs;
let request = new EndpointRequestController(req, res);

try {
    docs = await request.aggregate(staffmember, [{
        $lookup: {
            from: "branches",
            localField: "branch",
            foreignField: "_id",
            as: "branch"
        }
    },
    {
        $group: {
            _id: "$branch",
            count: {
                $sum: 1
            }
        }
    }]);
} catch (err) {
    return request.sendError("An error occurred while trying to find existing records.", err);
}
request.documentCount = docs.length;
request.sendResponse(docs);

它针对的是非常旧版本的Fantasy Land，因此不支持prefixed method names。

该项目已被放弃。我建议寻找替代方案。我推荐Fluture，它是成熟且维护良好的。在Sanctuary中也可以很好地工作。

在圣地IO上与避难所进行映射
