Package.json are used to obtain the pkg.The source and destination files are configured in "Build". That is, who is required to compress? Who will be generated after compression? Note that we will name the file name of the target files through the name and version of the Pkg.(PS: The contents of the Package.json mentioned above have finally found the place where he was applied.) The benefits are: for example, the management of the file version, you o

An analysis of the two-layer VLAN forwarding of Huawei Ethernet switches and its advantages. To solve the problem of VLAN introduced by Huawei Ethernet switches, we must first understand the benefits brought by VLAN introduction. Remember the corresponding instance. Therefore, it is very advantageous to study the following carefully. Packet forwarding thread: After VLAN is introduced, the packet forwarding thread of the L2 Switch has the following imp

MySQL databases support single-item and asynchronous replication. During the replication process, one server acts as the master server, and the other server acts as the slave server. As shown in. The master server writes the update information to a specific binary file. An index of the file is maintained to track log loops. This log can be recorded and sent to the slave server for updates. When an slave server is connected to the master server, the slave server will notify the master server to r

Elasticsearch is an advanced, high-performance, extensible open-source search engine that provides both structured and unstructured data for full-text search and real-time analysis. It features a RESTful API that can be easily integrated into existing Web architectures using HTTP. Therefore, in the case of high concurrency, we can use Nginx reverse proxy load balancer to multiple Elasticsearch servers. Architecture diagram: So what are the benefits o

Data can be uniquely identified by XML. Without XML, search software must understand how each database is built. This is actually impossible, because the description data of each database is different. With XML, books can be easily classified by authors, titles, ISBN numbers, or other standards in a standard way. It is very convenient to search for books.
