Apple Lunch PPT Writing a loader is pretty simple. A loader is just a file that exports a function. The compiler calls this function and passes the result of the previous loader or the resource file into it. The this context of the function is filled-in by the compiler with some useful methods that allow the loader to, among other things, change its invocation style to async or get query parameters. The first loader is passed one argument: the content of the resource file. The compiler expects a result from the last loader. The result should be a String or a Buffer (which is converted to a string), representing the JavaScript source code of the module. An optional SourceMap result (as JSON object) may also be passed. Does Aldi Take Credit Cards

Auto Body Facebook Post Ideas A single result can be returned in sync mode. For multiple results the this.callback must be called. In async mode this.async() must be called.

Business Risk Assessment Example The loaders are called from right to left. But in some cases loaders do not care about the results of the previous loader or the resource. They only care for metadata. The pitch method on the loaders is called from left to right before the loaders are called. If a loader delivers a result in the pitch method the process turns around and skips the remaining loaders, continuing with the calls to the more left loaders. data can be passed between pitch and normal call.

module.exports = function(content) { return someSyncOperation(content, this.data.value); }; module.exports.pitch = function(remainingRequest, precedingRequest, data) { if(someCondition()) { // fast exit return "module.exports = require(" + JSON.stringify("-!" + remainingRequest) + ");"; } data.value = 42; };
