Status](https://travis-ci.org/levp/try-with.svg?branch=master)](https://travis-ci.org/levp/try-with)\n\n# try-with\n\n**A utility for safe and convenient handling of managed resources in JavasScript.**\n\nThe purpose of this utility is to provide a convenient and safe way of using resources that must be manually released, such as remote connections and file handlers.  \n\nSimilar concepts:\n* [try-with-resource](https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html) in Java\n* [using statement](https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/using-statement) in C#. \n\n## Installing\n\nnpm: `npm i try-with`  \nyarn: `yarn add try-with`\n\n## Example\n\nA potential resource leak due to stream not being closed:\n\n```js\nconst stream = fs.createWriteStream(filePath);\n// Next line will throw if `data` is not one of the allowed types.\nstream.write(data);\n// Will never be called if previous line threw and someone caught the error.\nstream.close();\n```\n\nA safe variant of the above code:\n\n```js\nconst stream = fs.createWriteStream(filePath);\ntry {\n  stream.write(data);\n} finally {\n  stream.close();\n}\n```\n\nFunctionally equivalent to the code above but using `try-with`:\n\n```js\nconst tryWith = require('try-with');\n\ntryWith(fs.createWriteStream(filePath), stream =\u003e {\n  stream.write(data);\n});\n```\n\n## API\n\n`tryWith(object, action, [cleanupMethodOrName])`\n\n1. Invokes `action`, passing `object` to it as a parameter.\n2. After action is finished try to perform cleanup:  \n\t1. If third argument was omitted:  \n\t\t1. If `dispose` property exists on `object`, try to invoke it.  \n\t\t2. Else if `close` property exists on `object`, try to invoke it.  \n\t2. Else If third argument was provided and is a function, invoke it and pass `object` to it as a paramter.\n\t3. Else (third argument was provided but is not a function):\n\t\t1. If it is a string or a symbol, try to invoke a property with that key on `object`.\n\t\t2. Else convert third argument to string and try to invoke a property with that key on `object`.\n3. If an error was thrown when `action` was invoked, rethrow it.\n\n## Building and Testing\n\n`npm run build` or `npm run watch` to compile TypeScript.  \n`npm test` to run tests, make sure to compile before doing so.\n\n## License\nISC\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flevp%2Ftry-with","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flevp%2Ftry-with","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flevp%2Ftry-with/lists"}
