# --description--
|
|
|
|
Build a full stack JavaScript app that is functionally similar to this: <https://timestamp-microservice.freecodecamp.rocks/>. Working on this project will involve you writing your code using one of the following methods:
|
|
|
|
- Clone [this GitHub repo](https://github.com/freeCodeCamp/boilerplate-project-timestamp/) and complete your project locally.
|
|
- Use [our Replit starter project](https://replit.com/github/freeCodeCamp/boilerplate-project-timestamp) to complete your project.
|
|
- Use a site builder of your choice to complete the project. Be sure to incorporate all the files from our GitHub repo.
|
|
|
|
When you are done, make sure a working demo of your project is hosted somewhere public. Then submit the URL to it in the `Solution Link` field. Optionally, also submit a link to your project's source code in the `GitHub Link` field.
|
|
|
|
**Note:** Time zones conversion is not a purpose of this project, so assume all sent valid dates will be parsed with `new Date()` as GMT dates.
|
|
|
|
# --hints--
|
|
|
|
You should provide your own project, not the example URL.
|
|
|
|
```js
|
|
(getUserInput) => {
|
|
assert(
|
|
!/.*\/timestamp-microservice\.freecodecamp\.rocks/.test(getUserInput('url'))
|
|
);
|
|
};
|
|
```
|
|
|
|
A request to `/api/:date?` with a valid date should return a JSON object with a `unix` key that is a Unix timestamp of the input date in milliseconds (as type Number)
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/api/2016-12-25').then(
|
|
(data) => {
|
|
assert.equal(
|
|
data.unix,
|
|
1482624000000,
|
|
'Should be a valid unix timestamp'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
A request to `/api/:date?` with a valid date should return a JSON object with a `utc` key that is a string of the input date in the format: `Thu, 01 Jan 1970 00:00:00 GMT`
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/api/2016-12-25').then(
|
|
(data) => {
|
|
assert.equal(
|
|
data.utc,
|
|
'Sun, 25 Dec 2016 00:00:00 GMT',
|
|
'Should be a valid UTC date string'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
A request to `/api/1451001600000` should return `{ unix: 1451001600000, utc: "Fri, 25 Dec 2015 00:00:00 GMT" }`
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/api/1451001600000').then(
|
|
(data) => {
|
|
assert(
|
|
data.unix === 1451001600000 &&
|
|
data.utc === 'Fri, 25 Dec 2015 00:00:00 GMT'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
Your project can handle dates that can be successfully parsed by `new Date(date_string)`
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/api/05 October 2011, GMT').then(
|
|
(data) => {
|
|
assert(
|
|
data.unix === 1317772800000 &&
|
|
data.utc === 'Wed, 05 Oct 2011 00:00:00 GMT'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
If the input date string is invalid, the api returns an object having the structure `{ error : "Invalid Date" }`
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/api/this-is-not-a-date').then(
|
|
(data) => {
|
|
assert.equal(data.error.toLowerCase(), 'invalid date');
|
|
},
|
|
(xhr) => {
|
|
assert(xhr.responseJSON.error.toLowerCase() === 'invalid date');
|
|
}
|
|
);
|
|
```
|
|
|
|
An empty date parameter should return the current time in a JSON object with a `unix` key
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/api').then(
|
|
(data) => {
|
|
var now = Date.now();
|
|
assert.approximately(data.unix, now, 20000);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
An empty date parameter should return the current time in a JSON object with a `utc` key
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/api').then(
|
|
(data) => {
|
|
var now = Date.now();
|
|
var serverTime = new Date(data.utc).getTime();
|
|
assert.approximately(serverTime, now, 20000);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
