Proxy library used in NativeScript tooling. This library gives you methods to get, set and clear proxy settings respected by NativeScript tooling.
npm install proxy-libnull.#### getProxySettings definition
``TypeScript`
/**
* Get information about current proxy settings.
* @param {string | { credentialsKey: string, userSpecifiedSettingsFilePath: string }} params @optional CredentialsKey and path to file from which to get the information.
* @returns {Promise<{ proxy: string, rejectUnauthorized: boolean, username: string, password: string, protocol: string, port: string, hostname: string }>} Information about proxy settings
*/
getProxySettings(params: string | { credentialsKey: string, userSpecifiedSettingsFilePath: string }): Promise<{proxy: string, rejectUnauthorized: boolean, username: string, password: string, protocol: string, port: string, hostname: string}>;
#### getProxySettings examples
* Passing credentials key only - in this case the settings will be read from default location:`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.getProxySettings({ credentialsKey: "myCredKey" })
.then(proxySettings => console.log(proxySettings))
.catch(err => console.error("Error while getting proxy settings.", err));
* Passing credentialsKey and userSpecifiedSettingsFilePath - proxy settings will be read from this file:`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.getProxySettings({ credentialsKey: "myCredKey", userSpecifiedSettingsFilePath: "~/.local/share/myProxyFile.json" })
.then(proxySettings => console.log(proxySettings))
.catch(err => console.error("Error while getting proxy settings.", err));
* Passing credentials key as string - in this case the settings will be read from default location:
`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.getProxySettings("myCredKey")
.then(proxySettings => console.log(proxySettings))
.catch(err => console.error("Error while getting proxy settings.", err));
#### setProxySettings definition
`TypeScript`
/**
* Sets new proxy settings.
* @param {string | { proxyUrl: string, credentialsKey: string, rejectUnauthorized: boolean, username: string, password: string, userSpecifiedSettingsFilePath: string }} params Proxy settings
* @returns {Promise
*/
setProxySettings(params: string | { proxyUrl: string, credentialsKey: string, rejectUnauthorized: boolean, username: string, password: string, userSpecifiedSettingsFilePath: string }): Promise
#### setProxySettings parameters and examples
* Passing all settings:JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.setProxySettings({ proxyUrl: "http://192.168.1.102:8888", credentialsKey: "myCredKey", rejectUnauthorized: true, username: "myUsername", password: "myPassword", userSpecifiedSettingsFilePath: "~/.local/share/myProxyFile.json" })
.then(() => console.log("Successfully set proxy settings."))
.catch(err => console.error("Unable to set proxy settings", err));
* proxyUrl - this parameter is mandatory and it shows the url of the proxy. You can pass it as a single string argument of the method or as part of an object:
`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.setProxySettings({ proxyUrl: "http://192.168.1.102:8888" })
.then(() => console.log("Successfully set proxy settings."))
.catch(err => console.error("Unable to set proxy settings", err));
orJavaScript`
const proxyLib = require("proxy-lib");
proxyLib.setProxySettings("http://192.168.1.102:8888")
.then(() => console.log("Successfully set proxy settings."))
.catch(err => console.error("Unable to set proxy settings", err));
The proxyUrl may also contain the authentication information, in this case the call will be:`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.setProxySettings({ proxyUrl: "http://myUsername:myPassword@192.168.1.102:8888" })
.then(() => console.log("Successfully set proxy settings."))
.catch(err => console.error("Unable to set proxy settings", err));
orJavaScript`
const proxyLib = require("proxy-lib");
proxyLib.setProxySettings("http://myUsername:myPassword@192.168.1.102:8888")
.then(() => console.log("Successfully set proxy settings."))
.catch(err => console.error("Unable to set proxy settings", err));
* rejectUnauthorized - this parameter defines if Node.js errors for invalid certificates should be respected. In case you do not pass this value, it will be set to true, so based on the configuration, errors like self signed certificate in certificate chain may be thrown. Setting this value to false will disregard such errors.`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.setProxySettings({ proxyUrl: "http://192.168.1.102:8888", rejectUnauthorized: false })
.then(() => console.log("Successfully set proxy settings."))
.catch(err => console.error("Unable to set proxy settings", err));
* username and password - these parameters should be used in case the proxy requires basic authentication. Currently you can use them only on Windows. Passing only one of the values will throw error. You can either pass the two arguments or include the authentication in the proxyUrl as shown above. The passed values will be saved in Windows Credential Manager.`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.setProxySettings({ proxyUrl: "http://192.168.1.102:8888", username: "myUsername", password: "myPassword" })
.then(() => console.log("Successfully set proxy settings."))
.catch(err => console.error("Unable to set proxy settings", err));
* credentialsKey - this parameter defines the name of the entry in Windows Credential Manager, where the username and password will be persisted. If it is not passed, it has default value. This parameter has no effect in case there's no authentication arguments passed.`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.setProxySettings({ proxyUrl: "http://192.168.1.102:8888", username: "myUsername", password: "myPassword", credentialsKey: "myKey" })
.then(() => console.log("Successfully set proxy settings."))
.catch(err => console.error("Unable to set proxy settings", err));
* userSpecifiedSettingsFilePath - this parameter defines the path to the file where proxy settings (without authentication) will be persisted. In case it is not passed, it has default value.`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.setProxySettings({ proxyUrl: "http://192.168.1.102:8888", userSpecifiedSettingsFilePath: "~/.local/share/myProxyFile.json" })
.then(() => console.log("Successfully set proxy settings."))
.catch(err => console.error("Unable to set proxy settings", err));
#### clearProxySettings definition
`TypeScript`
/**
* Clears proxy settings.
* @param {string | { credentialsKey: string, userSpecifiedSettingsFilePath: string }} params @optional Options for credentials key and path to be cleaned.
* @returns {Promise
*/
clearProxySettings(params: string | { credentialsKey: string, userSpecifiedSettingsFilePath: string }): Promise
#### clearProxySettings examples
* Removing default settings:
`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.clearProxySettings()
.then(() => console.log("Successfully cleared proxy settings file."))
.catch(err => console.error("Unable to clear proxy settings", err));
* Removing settings from custom file:
`JavaScript`
const proxyLib = require("proxy-lib");
proxyLib.clearProxySettings({ userSpecifiedSettingsFilePath: "~/.local/share/myProxyFile.json" })
.then(() => console.log("Successfully cleared custom proxy settings file."))
.catch(err => console.error("Unable to clear proxy settings", err));
* Removing settings from custom Credentials Manager entry and default settings file:
`JavaScript``
const proxyLib = require("proxy-lib");
proxyLib.clearProxySettings({ credentialsKey: "myKey" })
.then(() => console.log("Successfully cleared custom proxy settings file and custom entry."))
.catch(err => console.error("Unable to clear proxy settings", err));
