javascript - Understanding npm package @-prefix: @angular/router -

-

in angular component router documentation stumbled on npm command have never seen before , don't understand going on:

npm install @angular/router --save

what meaning of @angular/router?

is whole string package name? dont find package when use search on npmjs.com. , commandline search return no such package:

npm search @angular/router                                                                                                                                           :no match found "@angular/router"

so @angular/ kind of prefix mechanism in npm? , how work?

this new feature of npm called 'scoped packages'. allow npm packages namespaced - package starts @angular/ grouped @angular folder in node_modules.

the reason scoped packages don't show in public search because lot of them private packages created organizations using npm's paid services, , they're not comfortable opening search until can totally they're not going make public shouldn't public - legal perspective, pretty understandable.

for more information, see npm docs, or angular docs

this follow question undefined reference rsa_generate_key in openssl? have openssl program generate rsa key, follows : #include <stdio.h> #include <openssl/rsa.h> #include <openssl/pem.h> int main(int argc, char* argv[]) { rsa *r = null; int ret; r = rsa_new(); bignum *bne = null; ret = rsa_generate_key_ex(r, 2048, bne, null); return 0; } when compile gcc -i../include rsatest.c -lcrypto -l. i undefined reference errors functions in libraries gdi32 , zlib. so correct this, have add -lz , -lgdi32, as gcc -i../include/ rsatest.c -lcrypto -lz -lgdi32 -l. my question is, aren't static libcrypto , libssl self sufficient? in why having add libraries make work? there option should have added while compiling library prevent this? i'm using 64 bit windows mingw compiler. made openssl library of msys , make.
