express - InversifyJS: dependency instantiation per HTTP Request -

i'm using inversify.js in project express. create connection neo4j database, , process has 2 objets:

1. the driver object - shared across application , created 1 time only
2. the session object - each http request should create session against driver, lifecyle same http request lifecycle (as long request ends, connection destroyed)

without insersify.js, problem solved using simple algorithm:

exports.getsession = function (context) { // 'context' http request    if(context.neo4jsession) {     return context.neo4jsession;   }   else {     context.neo4jsession = driver.session();     return context.neo4jsession;   } }; 

(example: https://github.com/neo4j-examples/neo4j-movies-template/blob/master/api/neo4j/dbutils.js#l13-l21)

to create static dependency driver, can inject constant:

container.bind<dbdriver>("dbdriver").toconstantvalue(new neo4jdbdriver());

how can create dependency instantiated once per request , retrieve them container?

i suspect must invoke container on middleware this:

this._express.use((request, response, next) => {     // container , create instance of neo4jsession request lifecycle     next(); }); 

thanks in advance.
