EKI NOTE :

"sebelumnya terimakasih kepada "Web App Project" Youtube Channel saya tambahkan penjelasan beliau & disini saya tambahkan juga pemahaman typescript saya & beberapa informasi penting dari video tutorial pada comment code" ,

"pentingnya dokumentasi karena disini saya memiliki pengalaman Research & Development tanpa dokumentasi, tanpa portfolio, tanpa bukti nyata adalah 'BULLSHIT' ".

==== STAGE 10 = MIGRATION EXPRESS ADAPTER TO FASTIFY ADAPTER

20211212-0045-EXPRESS-TO-FASTIFY-ADAPTER

/045

MySql Fastify : https://github.com/EKI-INDRADI/eki-latihan-nestjs-fastify-mysql

PostgreSql Fastify : https://github.com/EKI-INDRADI/eki-latihan-nestjs-fastify-postgresql

Mongodb (mongoose) Fastify : https://github.com/EKI-INDRADI/eki-latihan-nestjs-fastify-mongodb

RESPONSE :

BENCHMARK :

BENCHMARK NOTE :

npm i autocannon -g

autocannon -c 100 -d 40 -p 10 localhost:3000 ( express nestjs )

autocannon -c 100 -d 40 -p 10 localhost:3001 ( fastify nestjs )

all result : https://github.com/fastify/benchmarks

• backend ini sudah banyak menggunakan inject depedency dan perubahan middleware,

• tidak seperti benchmark list pada https://github.com/fastify/benchmarks yang polos tanpa ada inject dependency

• pada benchmark ini fastify adapter nestjs menunjukan kinerja 3x lipat lebih cepat dari express adapter nestjs

• untuk jangka panjang saya belum test lebih lanjut, tetapi jika saya mendapatkan informasi lebih lanjut saya akan infokan pada github ini

//============================ MULTER NOT SUPPORT FASTIFY ADAPTER
NOTE : https://docs.nestjs.com/techniques/file-upload (fastify tidak support multer multipart form data di nestjs)

silahkan coba depedency alternative lain, 

atau mungkin untuk file upload dapat menggunakan nestjs express secara terpisah, 

toh jika tujuannya ingin membuat microservices, 

memang seharusnya terpisah

==== /STAGE 10 = MIGRATION EXPRESS ADAPTER TO FASTIFY ADAPTER

mohon maaf lama update, karena tidak memiliki banyak waktu karena saya bekerja pada salah 1 perusahaan startup dengan waktu kerja 11-12 jam per hari

semoga dokumentasi ini bermanfaat cukup liat setiap branch nya, akan langsung paham (sudah dibuat komentar code untuk di pahami juga)

end video 04:24:41 [pagenation rekening done]

stage 8 - update manual raw query SQL

stage 9 - migrasi MySql to PostgreSql

stage 10 - migrasi express adapter nestjs to fastify adapter nestjs
