@exocet/value-flagger

This package was created as an alternative to pass null values through protobuf encoded JSON. It search for null values and creates a boolean flag indicating that field was null. This package doesn't use recursion so it's very fast.

Methods

encode(source[, options])

const { encode } = require('@exocet/value-flagger');

Encode a source object or array flagging the source searching for replaceValue and flagging the object key with the flagKey as property's prefix.

• source - object or array to encode.
• options.replaceValue - value to replace with flags, the default value is null.
• options.flagKey - string with the prefix to be added to encoded object keys, the default value is '__isNull_'.

Return value: the source object or array with encoding flags.

decode(source[, options])

const { decode } = require('@exocet/value-flagger');

Decode a source object or array removing flags from the source and adding original keys as properties with replaceValue as value.

• source - object or array to decode.
• options.replaceValue - value to replace flags, the default value is null.
• options.flagKey - string with the prefix to be removed from decoded object keys, the default value is '__isNull_'.

Return value: the source object without encoding flags and keys set to original values.

isObject(value)

const { isObject } = require('@exocet/value-flagger');

Checks if a value is an object.

Return value: boolean.

Tests are done with mocha, chai and nyc for coverage. The lint preset is based on airbnb preset.
