Usage
> For more use-cases see the testsjs
const tryCatchCallback = require('try-catch-callback')
`$3
> Pass a synchronous that returns some result and handle completion or errors in cb if given, otherwise it returns thunk which accepts that cb. It's possible to not work in "async mode", if that's the case try to use [try-catch-core][] for your case, which guarantees that cb is called only once and always in next tick, using [dezalgo][] and [once][].Params
*
{Function}: function to be called.
* [opts] {Object}: optional options, such as context and args
* [opts.context] {Object}: context to be passed to fn
* [opts.args] {Array}: custom argument(s) to be pass to fn, given value is arrayified
* [opts.passCallback] {Boolean}: pass true if you want cb to be passed to fn args
* [opts.return] {Boolean}: if true returns error/value and does not calls cb
* [cb] {Function}: callback with cb(err, res) signature.
* returns {Function} thunk: if cb not given. Example
`js
var tryCatch = require('try-catch-callback')tryCatch(function () {
return 'fox qux'
}, function done (err, res) {
if (err) return console.error(err)
console.log(res) // => 'fox qux'
})
`passing custom context
js
const tryCatch = require('try-catch-callback')tryCatch(function () {
console.log(this.foo) // => 'bar'
console.log(this.baz) // => 'qux'
return
${this.foo}/${this.baz}
}, {
context: { foo: 'bar', baz: 'qux' }
}, function done (err, res) {
if (err) return console.error(err)
console.log(res) // => 'bar/qux'
})
passing custom arguments
js
const tryCatchCallback = require('try-catch-callback')
const done = (err, res) => console.log(res) // => 'zzz123'
const opts = {
args: [ { foo: 'zzz' }, 123 ]
}tryCatchCallback((ctx, qux) => {
return ctx.foo + qux
}, opts, done)
`returning a thunk
js
const tryCatch = require('try-catch-callback')
const thunk = tryCatch((a, b) => {
return a + b + 3
}, { args: [1, 2] })thunk((err, res) => {
console.log(res) // => 6
})

Pull requests and stars are always welcome. For bugs and feature requests, please create an issue.
Please read the contributing guidelines for advice on opening issues, pull requests, and coding standards.
If you need some help and can spent some cash, feel free to contact me at CodeMentor.io too.In short: If you want to contribute to that project, please follow these things
1. Please DO NOT edit README.md, CHANGELOG.md and .verb.md files. See "Building docs" section.
2. Ensure anything is okey by installing the dependencies and run the tests. See "Running tests" section.
3. Always use
npm run commit to commit changes instead of git commit, because it is interactive and user-friendly. It uses [commitizen][] behind the scenes, which follows Conventional Changelog idealogy.
4. Do NOT bump the version in package.json. For that we use npm run release, which is [standard-version][] and follows Conventional Changelog idealogy.Thanks a lot! :)
Building docs
Documentation and that readme is generated using [verb-generate-readme][], which is a [verb][] generator, so you need to install both of them and then run verb command like that`
$ npm install verbose/verb#dev verb-generate-readme --global && verb
_Please don't edit the README directly. Any changes to the readme must be made in .verb.md._
Running tests
Clone repository and run the following in that cloned directory
$ npm install && npm test
