EZ XLM - XLM Transaction Simplifier
EZXLM is a simple utility that accepts blockchain transactions as received from the XLM (Stellar) Network and simplifies them for easier & more rapid parsing.
Installation
With npm
npm install ezxlmWith yarn
yarn add ezxlmExample
Take for example the following transaction...
const tx = {

}Contrast just calling the StellarSDK.fromXDR methods...
const StellarSdk = require('stellar-sdk')
const xdr_to_json = require('json-xdr').toJSON
tx.envelope = xdr_to_json(StellarSdk.xdr.TransactionEnvelope.fromXDR(tx.envelope_xdr, 'base64'));
tx.result_meta = xdr_to_json(StellarSdk.xdr.TransactionMeta.fromXDR(tx.result_meta_xdr, 'base64'));
tx.result = xdr_to_json(StellarSdk.xdr.TransactionResult.fromXDR(tx.result_xdr, 'base64'));...which produces the following complex transaction:

}Note the many levels & nested fields which are not present in the simplified transaction (much easier and faster to parse!)
Behind the scenes:
ezxlm manipulates the specified transaction via the following operations behind the scenes:
- Deleting the following fields
- _links
- ledger [FUNCTION]
- self [FUNCTION]
- account [FUNCTION]
- operations [FUNCTION]
- effects [FUNCTION]
- precedes [FUNCTION]
- succeeds [FUNCTION]
- transaction [FUNCTION]
- Converting the following fields from XDR and then to JSON
- envelope_xdr
- result_xdr
- Deleting the following XDR fields:
- envelope_xdr
- result_meta_xdr
- result_xdr
- fee_meta_xdr
- Recursively iterating through the transaction and where applicable:
- Deleting keys with null and undefined values
- Deleting empty arrays
- Deleting ext keys and corresponding values
- Converting nested asset codes into human friendly strings and collapsing them into their parent properties (see below)
- Converting nested ed25519 keys into common addresses and collapsing them into their parent properties (see below)
- Flattening simple _type objects (see below)
- Converting numerator / denominator based price information into simplified float values (see below)
- Removing null bytes from text fields
- Collapsing version objects into the parent object (see below)
- Merging operation children into the operation objects (see below)
- Merging results children into the result objects
- Merging data objects into their parent objects (see below)
- Merging body objects into their parent objects (see below)
- Merging tr objects into their parent objects (see below)
The resulting simplified transaction object is returned from the simplify method
assetCode conversion
ezxlm will convert the following:
"selling": {
"_type": "assetTypeCreditAlphanum4",
"alphaNum4": {
"assetCode": "VVNEAA==",
"issuer": {
"_type": "publicKeyTypeEd25519",
"ed25519": "6KYahh5gr2D4B3PgY0blxyy+Wdyt2jdgjVjvQlEdn9w="
}
}
}To the following:
"selling": {
"assetCode": "USD",
"issuer": "GDUKMGUGDZQK6YHYA5Z6AY2G4XDSZPSZ3SW5UN3ARVMO6QSRDWP5YLEX",
},Note: in this example, the ed25519 transformation has also been applied in accordance to the rules specified below.
ed25519 conversion
ezxlm will convert the following:
"sourceAccount": {
"_type": "keyTypeEd25519",
"ed25519": "mcfP1x5DZziNHLxXU1oyYLS+ujC/WNUI5MpshBvN2s4="
}To the following:
"sourceAccount": "GCM4PT6XDZBWOOENDS6FOU22GJQLJPV2GC7VRVII4TFGZBA3ZXNM55SV",This applies to all ed25519 fields
simple _type conversion
ezxlm will convert the following:
{
"buying": {
"_type": "assetTypeNative"
}
}To the following:
{
"buying": "assetTypeNative"
}
This conversion will only be applied to objects containing a _type property and no others.
price conversion
ezxlm will convert the following:
"price": {
"n": 1568229641,
"d": 300455075
}To the following:
"price": 5.219514568026518This is accomplished by dividing n by d and assigning it to price.
version conversion
ezxlm will collapse 'v1', 'v2', etc fields from:
"envelope": {
"_type": "envelopeTypeTx",
"v1": {
"tx" : {
// ...
}
}
}To the following:
"envelope" : {
"tx" : {
// ...
}
}operations conversion
For each operation, ezxlm will convert the following:
{
"body": {
"_type": "manageBuyOffer",
"manageBuyOfferOp": {
"selling": {
"_type": "assetTypeCreditAlphanum4",
"alphaNum4": {
"assetCode": "VVNEAA==",
"issuer": {
"_type": "publicKeyTypeEd25519",

},
"buyAmount": "0",
"price": {
"n": 1,
"d": 10000
},
"offerId": "378761140"
}
}
},To the following:
{
"body": {
"_type": "manageBuyOffer",
"selling": {
"_type": "assetTypeCreditAlphanum4",
"alphaNum4": {
"assetCode": "VVNEAA==",
"issuer": {
"_type": "publicKeyTypeEd25519",
"ed25519": "6KYahh5gr2D4B3PgY0blxyy+Wdyt2jdgjVjvQlEdn9w="

}
},
"buying": {
"_type": "assetTypeNative"
},
"buyAmount": "0",
"price": {
"n": 1,
"d": 10000
},
"offerId": "378761140"
}
}Note: Other conversions will be applied, including the collapsing of the body object into the parent operation (see below)
results conversion
For each result, ezxlm will convert the following:
{
"_type": "opInner",
"tr": {
"_type": "manageBuyOffer",
"manageBuyOfferResult": {
"_type": "manageBuyOfferSuccess",
"success": {
"offersClaimed": [],
"offer": {
"_type": "manageOfferDeleted"
}
}
}
}
}To the following:
{
"_type": "opInner",
"tr": {
"_type": "manageBuyOffer",
"manageBuyOfferResult": {
"_type": "manageBuyOfferSuccess",
"offersClaimed": [],
"offer": {
"_type": "manageOfferDeleted"
}
}
}
}**Note: Other conversion will be applied, including the collapsing of the tr object in the parent result (see below)
data coversion
ezxlm will convert the following:
{
"lastModifiedLedgerSeq": 32842603,

"offerId": "378761140"
// ...
}
}
}To the following:
{
"_type": "manageBuyOffer"
"buyAmount": "0",
"offerId": "378761140"
}
