Once the\nfunction is called for the first time the return value of the original\nfunction is saved in `fn.value` and subsequent calls will continue to\nreturn this value.\n\n```javascript\nvar once = require('once')\n\nfunction load (cb) {\n cb = once(cb)\n var stream = createStream()\n stream.once('data', cb)\n stream.once('end', function () {\n if (!cb.called) cb(new Error('not found'))\n })\n}\n```\n", "readmeFilename": "README.md", "bugs": { "url": "https://github.com/isaacs/once/issues" }, "homepage": "https://github.com/isaacs/once#readme", "_id": "once@1.3.2", "_shasum": "d8feeca93b039ec1dcdee7741c92bdac5e28081b", "_resolved": "https://registry.npmjs.org/once/-/once-1.3.2.tgz", "_from": "once@>=1.3.2 <1.4.0" } |
