--description--
https://timestamp-microservice.freecodecamp.rocks と同じような機能を持つ、フルスタック JavaScript アプリを構築してください。 プロジェクトに取り組むにあたり、以下の方法のうち 1 つを用いてコードを記述します。
- GitHub リポジトリをクローンし、ローカル環境でチャレンジを完了させる。
- Replit スタータープロジェクトを使用して、プロジェクトを完了させる。
- 使い慣れたサイトビルダーを使用してプロジェクトを完了させる。 必ず GitHub リポジトリのすべてのファイルを取り込む。
If you use Replit, follow these steps to set up the project:
- Start by importing the project on Replit.
- Next, you will see a
.replit
window. - Select
Use run command
and click theDone
button.
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.
(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)
(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
(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" }
(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)
(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" }
(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
(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
(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);
}
);
