@neo9/n9-mongodb-client

n9-mongodb-client

A client to use easily MongoDB official driver.

Upgrade to V1 (from v 0.33)

First, upgrade to V 1.0.0-rc.0

Breaking changes (due to mongodb driver upgrade) :

• Index creation/update/deletion now use parameter of type IndexSpecification
• Sort param is no more an object, it is a proper type Sort
• global.dbClient.isConnected should now be replaced by MongoUtils.isConnected

Other Notable Breaking Changes

• Name changed from @neo9/n9-mongo-client to @neo9/n9-mongodb-client
• Cursor are now N9FindCursor or N9AggregationCursor
• MongoClient is renamed to N9MongoDBClient
• MongoUtils functions are renamed to the UPPER_CASE equivalent :
  • oid → TO_OBJECT_ID
  • oids → TO_OBJECT_IDS
  • connect → CONNECT
  • And so on ...
• We removed all usage of global variable :
  • global.log → A logger is required as parameter of a new N9MongoDBClient
  • global.db → MongoUtils.CONNECT return it, it has to be pass to the new N9MongoDBClient settings
  • global.dlClient → MongoUtils.CONNECT return it too now, as mongodbClient and is required to call MongoUtils.DISCONNECT

Upgrade main steps

• yarn remove @neo9/n9-mongo-client && yarn add @neo9/n9-mongodb-client@^1.0.0-rc.8 (this also upgrade all transitive dependencies)

• Rename usage : find ./ -mindepth 1 -type f -not -path "./node_modules/*" -not -path "./.git/*" -name "*.ts" -exec sed -i -e 's#@neo9/n9-mongo-client#@neo9/n9-mongodb-client#g' {} +

• Remove old mongodb types :

  • yarn remove @types/mongodb
  • find ./ -mindepth 1 -type f -not -path "./node_modules/*" -not -path "./.git/*" -name "*.ts" -exec sed -i -e "s#from 'mongodb'# from '@neo9/n9-mongodb-client/mongodb'#g" {} +
  • ⚠️ find ./ -mindepth 1 -type f -not -path "./node_modules/*" -not -path "./.git/*" -name "*.ts" -exec sed -i -e "s#AggregationCursor<#N9AggregationCursor<#g" {} + Can fix most of cases
  • ⚠️ find ./ -mindepth 1 -type f -not -path "./node_modules/*" -not -path "./.git/*" -name "*.ts" -exec sed -i -e "s# Cursor<# N9FindCursor<#g" {} + Can fix most of cases
  • ⚠️ find ./ -mindepth 1 -type f -not -path "./node_modules/*" -not -path "./.git/*" -name "*.ts" -exec sed -i -e "s#Cursor,##g" {} + Can fix most of cases
  • ⚠️ find ./ -mindepth 1 -type f -not -path "./node_modules/*" -not -path "./.git/*" -name "*.ts" -exec sed -i -e "s#{ FilterQuery } from '@neo9/n9-mongodb-client/mongodb';#{ FilterQuery } from '@neo9/n9-mongodb-client';#g" {} + Can fix most of cases
  • ⚠️ find ./ -mindepth 1 -type f -not -path "./node_modules/*" -not -path "./.git/*" -name "*.ts" -exec sed -i -e "s#{ Cursor } from '@neo9/n9-mongodb-client/mongodb';#{ N9FindCursor } from '@neo9/n9-mongodb-client';#g" {} + Can fix most of cases

• Upgrade dependencies required : yarn upgrade typescript@^5.2.2 @neo9/n9-coding-style@^5.1.2 prettier@^3.0.3

  • Upgrade tsconfig for node 16+ :
    • yarn add -D @tsconfig/node16
    • yarn remove @tsconfig/node14
    • Upgrade tsconfig.json file
      • sed -i 's#node14#node16#g' tsconfig.json

• Upgrade MongoDb used for tests to version 6.0+

• Change MongoDB types imports from import ... from 'mongodb'; to import ... from '@neo9/n9-mongodb-client/mongodb';

• Use Node.js version 18 or greater.

• Use new count function on N9AggregationCursor that wasn't available on AggregationCursor

• It's a good time to use new version of @neo9/n9-mongodb-migration V1 : yarn upgrade @neo9/n9-mongodb-migration@^1.0.0-rc.0
