Add A 'ttl' (time-to-live) Option to Levelup for Put() & Batch()

level-ttl

Add a ttl (time-to-live) option to levelup for put() and batch().

Usage

If you are upgrading: please see UPGRADING.md.

Augment levelup to handle a new ttl option on put() and batch() that specifies the number of milliseconds an entry should remain in the data store. After the TTL, the entry will be automatically cleared for you.

Requires levelup, level or one of its variants like level-rocksdb to be installed separately.

const level = require('level')
const ttl = require('level-ttl')

const db = ttl(level('./db'))

// This entry will only stay in the store for 1 hour
db.put('foo', 'bar', { ttl: 1000 * 60 * 60 }, (err) => {
  // ..
})

db.batch([
  // Same for these two entries
  { type: 'put', key: 'foo', value: 'bar' },
  { type: 'put', key: 'bam', value: 'boom' },
  { type: 'del', key: 'w00t' }
], { ttl: 1000 * 60 * 5 }, (err) => {})

If you put the same entry twice, you refresh the TTL to the last put operation. In this way you can build utilities like session managers for your web application where the user's session is refreshed with each visit but expires after a set period of time since their last visit.

Alternatively, for a lower write-footprint you can use the ttl() method that is added to your levelup instance which can serve to insert or update a ttl for any given key in the database - even if that key doesn't exist but may in the future!

db.put('foo', 'bar', (err) => {})
db.ttl('foo', 1000 * 60 * 60, (err) => {})

level-ttl uses an internal scan every 10 seconds by default, this limits the available resolution of your TTL values, possibly delaying a delete for up to 10 seconds. The resolution can be tuned by passing the checkFrequency option to the ttl() initialiser.

// Scan every second
const db = ttl(level('./db'), {
  checkFrequency: 1000
})

Of course, a scan takes some resources, particularly on a data store that makes heavy use of TTLs. If you don't require high accuracy for actual deletions then you can increase the checkFrequency. Note though that a scan only involves invoking a levelup ReadStream that returns only the entries due to expire, so it doesn't have to manually check through all entries with a TTL. As usual, it's best to not do too much tuning until you have you have something worth tuning!

Default TTL

You can set a default ttl value for all your keys by passing the defaultTTL option to the ttl() initialiser. This can be overridden per operation. In the following example A will expire in 15 minutes while B will expire in one minute.

const db = ttl(level('./db'), {
  defaultTTL: 15 * 60 * 1000
})

db.put('A', 'beep', (err) => {})
db.put('B', 'boop', { ttl: 60 * 1000 }, (err) => {})

opts.sub

You can provide a custom storage for the meta data by using the opts.sub property. If it's set, that storage will contain all the ttl meta data. A use case for this would be to avoid mixing data and meta data in the same keyspace, since if it's not set, all data will be sharing the same keyspace.

A db for the data and a separate to store the meta data:

const level = require('level')
const ttl = require('level-ttl')
const meta = level('./meta')

const db = ttl(level('./db'), { sub: meta })

const batch = [
  { type: 'put', key: 'foo', value: 'foo value' },
  { type: 'put', key: 'bar', value: 'bar value' }
]

db.batch(batch, { ttl: 100 }, function (err) {
  db.createReadStream()
    .on('data', function (data) {
      console.log('data', data)
    })
    .on('end', function () {
      meta.createReadStream()
        .on('data', function (data) {
          console.log('meta', data)
        })
    })
})

Shutting down

level-ttl uses a timer to regularly check for expiring entries (don't worry, the whole data store isn't scanned, it's very efficient!). The db.close() method is automatically wired to stop the timer but there is also a more explicit db.stop() method that will stop the timer and not close the underlying levelup instance.

Как создать потрясающие настраиваемые радиокнопки, используя только HTML и CSS

В этом руководстве вы узнаете, как создавать потрясающие настраиваемые радиокнопки, используя только HTML и CSS. Чтобы создать удивительные пользовательские радиокнопки, используя только HTML и CSS. Во-первых, вам нужно создать два файла: один файл HTML, а другой — файл CSS.

1: Сначала создайте файл HTML с именем index.html.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Custom Radio Buttons | Codequs</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
  <div class="wrapper">
    <div class="title">Select your option</div>
    <div class="box">
      <input type="radio" name="select" id="option-1">
      <input type="radio" name="select" id="option-2">
      <input type="radio" name="select" id="option-3">
      <input type="radio" name="select" id="option-4">
      <label for="option-1" class="option-1">
        <div class="dot"></div>
        <div class="text">Gamer</div>
      </label>
      <label for="option-2" class="option-2">
        <div class="dot"></div>

        <div class="text">Developer</div>
      </label>
    </div>
  </div>

</html>

2: Во-вторых, создайте файл CSS с именем style.css.

 

@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@200;300;400;500;600;700&display=swap');

Cách tạo các nút radio tùy chỉnh tuyệt vời chỉ sử dụng HTML và CSS

Trong hướng dẫn này, bạn sẽ học cách tạo các Nút radio tùy chỉnh tuyệt vời chỉ bằng HTML và CSS. Để tạo các Nút radio tùy chỉnh tuyệt vời chỉ bằng HTML và CSS. Đầu tiên, bạn cần tạo hai Tệp, một Tệp HTML và một tệp khác là Tệp CSS.

1: Đầu tiên, tạo một tệp HTML với tên là index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Custom Radio Buttons | Codequs</title>
    <link rel="stylesheet" href="style.css">

  <div class="wrapper">
    <div class="title">Select your option</div>
    <div class="box">
      <input type="radio" name="select" id="option-1">
      <input type="radio" name="select" id="option-2">
      <input type="radio" name="select" id="option-3">
      <input type="radio" name="select" id="option-4">
