19 | 20 | ### Highlights 21 | This is a synchronous JavaScript interface for the HTML5 localStorage API that-- 22 | 1) __transparently sets/gets__ key values using data "types" such as Array, BigInt, Boolean, Date, Float, Integer, Object and String; 23 | 2) __provides__ lightweight __data obfuscation__; 24 | 3) intelligently __compresses strings__ (to save storage space); 25 | 4) __facilitates robust lookup__ including query by key (name), query by (key) value and query by existence (boolean check); 26 | 5) __enforces segmented shared storage__ within the same domain by prefixing keys; 27 | 6) lets you __respond to localStorage change events__ on the same page/tab that fired them; 28 | 7) __broadcasts__ change events across the origin for the benefit of other windows/tabs; 29 | 8) lets you __easily work with arrays__ using dedicated Array Keys; and 30 | 9) offers __Memory Keys__ (that can be backed up to disk) for the fastest read times possible. 31 | 32 |

37 | 38 | ## Trusted Installation 39 | 40 | ### Include via CDN 41 | 42 | ```js 43 | 48 | ``` 49 | Since the source file is delivered from a repository over which we have no control, best practices demand we do not trust it. Thus we use [Subresource Integrity](https://archive.ph/ll97b) (SRI) to prevent tampering. 50 | 51 | Unlike the [BrowseAloud story](https://archive.ph/vuKft), my library is a static, self-contained resource which can be fully protected by SRI. 52 |

53 | 54 | ## Application: 55 | Primary usage is the ability to seamlessly *set/get* keys for typical data types without having to perform conversion in your own logic. Toss out an integer and have it returned. Throw an array into storage and get it back, including the ability to add and remove elements. Are you also working with dates, booleans or objects? No problem. While it’s not rocket science to convert, track and restore your own data, letting the interface handle that chore for you is exceptionally convenient. It also saves you the hassle having to incorporate conversion logic in your application. To track a data type, storage management requires one additional byte of memory overhead per key value, so an eight-byte array, for example, will be stored using nine bytes. 56 | 57 | Data Protection
Since localStorage data resides in a client environment where the information is not protected from access or tampering, this data can be rendered unintelligible at the expense of a small amount of memory overhead. Depending on your application, this may be worth the tradeoff. To hide your data, key values may be obfuscated using *safeset/safeget*. A master scramble key may be set globally, or individual scramble keys may be used per each *safeset/safeget* call. Scramble keys can be any value and of any type (array, boolean, date, float, integer, etc.) Key values that have been *safeset* with an individual scramble key can always be retrieved, but cannot be reconstructed apart from the exact scramble key with which they were obfuscated. For convenience, the global scramble key is stored in the interface. For security, individual scramble keys are not. The global scramble key may be accessed using *setscramblekey/getscramblekey* methods. Individual scramble keys must be remembered. 58 | 59 | Scrambling is not encryption. For example, no attempt is made to conceal data lengths by artificially padding to a minimum length. This would be counterproductive to minimizing memory usage. 60 | 61 | Compression
Strings are intelligently compressed on‑the‑fly when storing. This means they are first analyzed to determine whether compression would lower the actual byte count (not string length) needed for storage, and if so, are silently compressed for you. This works well for common English texts (short‑length, 7‑bit ASCII), and not much else. If desired, you may manually *crunch/uncrunch* your own key values. 62 | 63 | Robust Access
One may query by key (the standard way) or query by existence (*haskey* checks if the key is in the store while *hasval* checks if the store contains the value). You can query for duplicate values with *listdupes* and *showdupes*. Convenience methods prevent writing over an existing key *(softset)* and permit deleting a key immediately upon retrieval *(chopget)*. You can easily query and update an array key using *push/pull* and *contains* without the need for external array logic. Key values can be checked for their data type, for example, using *isfloat*, and keys can be renamed (*rename*). Lastly, bypass methods *(forceset/forceget)* permit accessing localStorage directly. 64 | 65 | Storage Management
Since HTML5 localStorage is accessible to all processes running in the browser for the domain visited, it is advisable to have an interface that segments access. To that end, the use of prefixed keys is strongly encouraged, and localDataStorage will only read/write/delete its own values. Unlike the HTML5 API, there is no method in the interface to clear all storage keys, only all prefixed keys. At any time, memory usage can be tracked against key values and key names, for example, using *valbytes* or *keybytes*. 66 | 67 | The domain of operation for HTML5 localStorage is specific to the protocol, host & port; and multiple instances of localDataStorage can be run against the same domain at the same time. It is emoji‑friendly 🤪🤷‍♂️💖👍, which is to say that key names and their values, as well as scramble keys and storage prefixes, are multibyte Unicode‑safe. 68 | 69 | 70 | ## Events 71 | The native localStorage change event is... lacking. Per the misguided whims of the interweb gods, a web page in your browser isn’t permitted to listen to change events that it alone triggers. However, in the event you'd like to keep an ear out for changes, localDataStorage will let you. The interface fires a custom event on key value changes, such as those made by the *chopget*, *clear*, *forceset*, *remove*, *rename*, *safeset*, *set* and *softset* methods. The event returns an activity timestamp and message, as well as expected details about the affected key with its old and new values (and old and new data types, etc.) Insert your own function here to catch the changes. This code snippet shows what's exposed so you can respond accordingly: 72 | 73 | ```js 74 | const nowICanSeeLocalStorageChangeEvents = function( e ) { 75 | console.log( 76 | "subscriber: " + e.currentTarget.nodeName + "\n" + 77 | "date: " + e.detail.date + "\n" + 78 | "timestamp: " + e.detail.timestamp + "\n" + 79 | "prefix: " + e.detail.prefix + "\n" + 80 | "message: " + e.detail.message + "\n" + 81 | "method: " + e.detail.method + "\n" + 82 | "old key: " + e.detail.oldkey + "\n" + 83 | "new key: " + e.detail.newkey + "\n" + 84 | "old value: " + e.detail.oldval + "\n" + 85 | "new value: " + e.detail.newval + "\n" + 86 | "old type: " + e.detail.oldtype + "\n" + 87 | "new type: " + e.detail.newtype + "\n" + 88 | "old base: " + e.detail.oldbase + "\n" + 89 | "new base: " + e.detail.newbase 90 | ); 91 | 92 | // respond to key change by passing key name 93 | myCustomChangeFunction( e.detail.oldkey ); 94 | } 95 | 96 | document.addEventListener( 97 | "localDataStorage" 98 | , nowICanSeeLocalStorageChangeEvents 99 | , false 100 | ); 101 | 102 | ``` 103 |

104 | 105 | 106 | ## Dependencies: 107 | There are no external dependencies. 108 | 109 | Internally, obfuscation is supported by [fisherYatesDurstenfeldKnuthShuffle](#refs) and [aleaPRNG](#refs) (my own libraries). 110 |

111 | 112 | 113 | ## SemVer: 114 | Recognizing there is no way I can predict how a change in my software will affect users, I still use [semantic versioning](https://archive.ph/Z02ta) (semver) to signal those changes. 115 | 116 | Per [Hyrum’s Law](https://archive.ph/IGprL), I gently suggest you may enjoy, but I do not promise you will actually have a bug-free upgrade experience. 117 |

118 | 119 | 120 | ## Falsy pedantics: 121 | There is a universe of difference between a variable considered _null_ and one that is _undefined_. In JavaScript, both of these are [falsy](https://archive.ph/PCDvQ) and both are primitive types (despite what `typeof null` tells you). Yet they are also quite distinct. 122 | 123 | A value of null means the variable has been set to nothing whatsoever, but it has been set nevertheless. 124 | 125 | In contrast, an undefined variable has no value because the variable itself doesn't exist (it is undeclared). 126 | 127 | With null, the variable is set to no value but if undefined, it isn't set. The distinction is important. The native localStorage API returns _null_ when getting a key that doesn't exist. (Pedantically, this is false.) 128 | 129 | However, localDataStorage returns _undefined_ for an undeclared key simply because it isn't present in the store. Further, you could actually store a null value key using localDataStorage if your use case required, but at no time will non-existant keys be returned as nulls. The distinction is just. Too. Important. 130 |

now we include the 2-byte embedded marker (total data) 646 | 647 |

648 | // show memory required to store key name 649 | > localData.keybytes( 'dupekey4' ) 650 | 651 | --> "48.00 bytes" 652 |
the prefix ('passphrase.life' + '.') is 32 bytes, plus key name is 16 bytes more ('dupekey4' ), yielding 48 bytes 653 | 654 |

8 bytes for raw value and 48 bytes for name, i.e. valbytes + keybytes 663 | 664 |

665 | // key name + total value (include value marker byte) 666 | > localData.bytesall( 'dupekey4' ) 667 | 668 | --> "60.00 bytes" 669 |

4 | 5 | There is a difference between the memory required to store a key value and the memory consumed in the process. For JavaScript, _consumption_ is doubled that of _storage_. 6 | 7 | The following table illustrates memory storage and consumption, for both a key name and its value, as well as the available methods for determining each: 8 | 9 | Prefix | Example | Key

24 | **Footnotes:**
25 | ⑴ includes the namespace prefix (6 bytes, in this example)
26 | ⑵ includes the data type marker flag (always 1 byte)
27 | ⑶ text compression—even on a small scale—makes an impact (uncompressed this string consumes 24 bytes, not 17)
28 | ⑷ note that string length is inconsequential (13 in this case); for storage the only metric that counts is byte count
29 | ⑸ dates are automatically stored compressed, providing a degree of obfuscation as well
30 | ⑹ numbers (floats and integers) are automatically stored compressed, providing a degree of obfuscation as well 31 | --------------------------------------------------------------------------------
