Let environment variables override configuration set by config.json
and/or app.set()
Behavior changes
- datasources.json now support dynamic configuration through
env-vars and config.json
- component-config.json will first consider env-var
for resolving dynamic conf, then fallback to config.json
- middleware.json will first consider env-var for resolving
dynamic conf, then fallback to config.json
- for all the dynamic confg, unresolved conf will return as `undefined`
Example:
Consider the following server/datasources.json
```
{
"mysql" : {
"name" : "mysql_db",
"host" : "${MYSQL_DB_HOST}",
...
}
}
```
Now you can provide the parameter through
an environment variable:
```
$ MYSQL_DB_HOST=127.0.0.1 node .
```
or you can set the value in server/config.json
```
{
"MYSQL_DB_HOST": "127.0.0.1"
}
```
