Common YT/YQL/QC data formatting library.
Function accepts data in Unipika-YSON format (hereinafter referred to as the - Unipika), or, if converter is presented, in any other format and formats data according to its type. Currently two built-in converters are presented:
- YSON to Unipikа
- YQL to Unipika
| Source format | Types |
|---|---|
| YSON | string, number, int64, uint64, double, map, list, null |
| YQL | yql.string, yql.int64, yql.uint64, yql.double, yql.struct, yql.dict, yql.list, yql.tuple, yql.null, yql.yson, yql.pg.* - PostgreSQL Data Types in YQL are being formatted as string |
Similar in meaning types are displayed similarly. For example, int64 and yql.int64, map and yql.struct, etc.
It is assumed that types can't be mixed in arbitrary way, that is, for example, list can't have elements of type yql.string, nevertheless, library doesn't attempt to fix invalid data in this case. When using built-in converter this situation shouldn't happen. Also, for example, only YSON types can have attributes, for the rest of types special field $attributes is pointless.
| Name | Type | Default value | Description |
|---|---|---|---|
| normalizeUrl | (url: string) => string |
(url) => new URL(url).toString() |
Optional pararmeter that allows to override default behavior of utils.normalizeUrl. Default implementation uses encodeURI(url) and returns empty string if the call throws an exception. The result of call settings.normalizeUrl(url) injects to DOM tree "as is" as value of href-attributes, so you have to sanitize returned value to prevent XSS. |
| validateSrcUrl | (url: string) => boolean |
() => false |
Function, which accepts source url for TaggedType types and returns whether it is allowed to be downloaded. If settings in not defined, TaggedType types (images, audio, video) will be formatted as StructType |
| format | String | 'json' |
[YSON-specific] Affects displaying YSON types. Serialization to text yson or json is supported. These ways of representation are described in YT documentation. |
| decodeUTF8 | Boolean | true |
[YSON-Converter][YSON-specific] Setting is passed to the converter (YSON to Unipikа). Indicated whether to try decode the data. The data received from YT with the setting { encode_utf8 = false } should not be decoded (also is means that all strings are valid UTF-8 sequences, that is, they are not binary). By default the data from YT is received with the setting { encode_utf8 = true } and should be decoded; strings that cannot be decoded are marked as binary. |
| showDecoded | Boolean | true |
[NCP][YSON-specific] Indicates whether the decoded data should be displayed or the data in the form in which it is received from YT. |
| binaryAsHex | Boolean | true |
[NCP][YSON-specific] Indicates whether binary strings should be displayed as a sequence of HEX-digits. |
| asHTML | Boolean | true |
Return serialized data in plain text or html. |
| break | Boolean | true |
Put hyphens and indents or return everything as a single line. |
| indent | Number | 4 |
Indent size. |
| compact | Boolean | false |
The mode in which complex types like map, list, yql.struct and so on, are displayed more compact if contain only one element. |
| highlightControlCharacter | Boolean | false |
Enables highlighting of special control characters in html strings. |
| escapeWhitespace | Boolean | true |
[NCP]The mode in which hyphens and tab characters are not escaped. With this option it is convenient to view formatted data like stack-traces. |
| escapeYQLStrings | Boolean | true |
[NCP][YQL-Converter]The mode in which no symbols are escaped at all, so that user can get "raw" data. |
| nonBreakingIndent | Boolean | true |
The mode in which indents, spaces in key-value separator, and spaces in string binary representation are nonbreaking ( symbol). |
| omitStructNull | Boolean | false |
[YQL-Converter] Indicates whether to skip keys with null value in yql.struct type. |
| maxListSize | Number | undefined |
[YQL-Converter] Maximum allowed size of list nodes (yql.list, yql.dict, yql.struct, yql.tuple, yql.stream). If value > 0 is set, node will be truncated to this value. |
| maxStringSize | Number | undefined |
[YQL-Converter] Maximum allowed size of strings (yql.string, yql.utf8). If value > 0 is set, string will be truncated to this value. |
| limitMapLength | Number | undefined |
Maximum allowed size of all map nodes. If value > 0 is set, node will be truncated to this (value - 1). |
| limitListLength | Number | undefined |
Maximum allowed size of all list nodes. If value > 0 is set, node will be truncated to this (value - 1). |
| treatValAsData | Boolean | false |
If val is among data fields, it may be treated two ways: as normal object key (if treatValAsData is not set or is set to false) or it's value will be set as overall $value (if treatValAsData is set to true). In most cases this setting should not be set. |
[YQL-Converter] - Options affects only data conversion from YQL format.
[YSON-Converter] - Options affects only data conversion from YSON format.
[YSON-Specific] - Options affects only YSON types representation and should not affect other types representation.
[NCP] - (Non copy-pastable) this representation is used to improve readability, but is not valid; copying and using such data may cause an error.
Format function wrapper, data is passed in YSON format, YSON to Unipika converter is used.
Format function wrapper, data is passed in YQL format (in the list [data, dataType]), YQL to Unipika converter is used.
Plugins yql-date, yql-datetime and yql-timestamp do formatting of date by Date.prototype.toISOString().
If it is required it is better to use moment.js and rewrite the plugins.
