bunyan-remote can be used with the following optional properties:
__allowedIPs__: An array of IP expressions where "" signifys any (e.g 10.* - all IP's that start with 10.X.X.X)
* __auth__: One of the following options:remoteBunyan.AUTH_NONE
* ____: No authentication required by Bunyan Remote DevTool.remoteBunyan.AUTH_KEY
* ____: Prompt Bunyan Remote DevTool for a key.remoteBunyan.AUTH_USER
* ____: Prompt Bunyan Remote DevTool for a username and password.authenticate
* ____: A string, or a function which verifies the authentcation of the client.
When using AUTH_KEY or AUTH_USER, you can set the authenticate property to either a string or a function.
If auth is set to AUTH_KEY then the authenticate property will be compared to a regular token string.
If auth is set to AUTH_USER then the authenticate property will be compared to a combination of the username and password in the format username:password.
#### Examples
The following example uses a simple key for authentication:
`javascript`
logger.addStream(remoteBunyan({
auth: remoteBunyan.AUTH_KEY,
authentication: 'MY-SECRET-KEY'
}));
You can also specify a function that returns a boolean wether to allow or deny the authentication request:
`javascript`
var TOKENS = [ 'SECRET-KEY-1', 'SECRET-KEY-2' ];
logger.addStream(remoteBunyan({
auth: remoteBunyan.AUTH_KEY,
authentication: function (token) {
return TOKENS.indexOf(token) !== -1;
}
}));
If you're working with asynchronous operations you can do one of two things. One return function (accept, reject) where the parameters indicate to accept/reject the request:
`javascript`
logger.addStream(remoteBunyan({
auth: remoteBunyan.AUTH_USER,
authentication: function (token) {
return function (accept, reject) {
fs.readFile('./credentials.txt', { encoding: 'utf8' }, function (data) {
var tokens = data.split('\n');
if (tokens.indexOf(token) >= 0) {
accept();
} else {
reject();
}
});
};
}
}));
or better yet return an ES6 Promise: (recommended)
`javascript`
logger.addStream(remoteBunyan({
auth: remoteBunyan.AUTH_USER,
authentication: function (token) {
return new Promise(function (accept, reject) {
fs.readFile('./credentials.txt', { encoding: 'utf8' }, function (data) {
var tokens = data.split('\n');
if (tokens.indexOf(token) >= 0) {
accept();
} else {
reject();
}
});
};
}
}));
