我应该如何使用tsd类型来组织打字稿模块/软件包？

Question

I've got quite a large TS-project with numbers of internal libraries that are linked to each other as npm packades. Sometimes in .ts i need to put a references to some ambient or external definitions, provided by TSD, like this: /// <reference path="../../typings/tsd.d.ts" /> Each package includes own .d.ts files referencing to ...root.../typings/tsd.d.ts .

So, when i install a dependency package inside of another one, there can be a multiple definition for some ambient stuff, such as ...root.../typings/node/node.dt . And it causes transpiling errors Duplicate identifier .

I think you all know that problem. But i've spent about a day googling and reading and trying numbers of solutions that didn't work fine. :(

Please, show me a way out of this. Tell me how you do it.

Hmm... A weird idea has come. Put in all projects a postinstall hook script that changes the typings/tsd.d.ts and replaces paths of duplicating definition files to the parent poject's ones, something like this: /// <reference path="../../../../typings/node/node.d.ts" />

It's dirty but could work fine

 var fs = require('fs'); var path = require('path'); function searchParentTypingPath(currentPath, moduleName, depth){ if (!depth) depth = 1; if (depth>4) return null; try{ var filePath = currentPath+'/typings/'+moduleName+'/'+moduleName+'.d.ts'; fs.accessSync(filePath); return filePath; } catch(e){ return searchParentTypingPath(currentPath+'/..', moduleName, depth+1); } } module.exports = function (tsdFilePath, verbose){ var tsdContent = fs.readFileSync(tsdFilePath).toString(); var resultContent = ''; tsdContent.split('\\n').forEach(function(line){ var match = line.match(/^\\/\\/\\/\\s+<reference path="([\\/a-zA-Z0-9_\\-.]+)"\\s*\\/>/); if (!match) { resultContent+=line+'\\n'; return; } var modulePath = match[1]; if (!modulePath.match(/^\\w+/)) {// it's not provided by TSD resultContent+=line+'\\n'; return; } var moduleName = path.basename(modulePath, '.d.ts'); var parentPath = searchParentTypingPath(path.dirname(tsdFilePath)+'/../..', moduleName); resultContent+='/// <reference path="'+(parentPath||modulePath)+'" />\\n'; }); if (verbose) { console.log(resultContent); return resultContent; } fs.writeFileSync(tsdFilePath, resultContent); };
