Application Configurations

+ * + *

+ * The config module exports a singleton object representing all + * configurations for this application deployment. + *

+ * + *

+ * Application configurations are stored in files within the config directory + * of your application. The default configuration file is loaded, followed + * by files specific to the deployment type (development, testing, staging, + * production, etc.). + *

+ * + *

+ * For example, with the following config/default.yaml file: + *

+ * + * 
+ *   ...
+ *   customer:
+ *       initialCredit: 500
+ *       db:
+ *           name: customer
+ *           port: 5984
+ *   ...
+ *
+ * + *

+ * The following code loads the customer section into the CONFIG variable: + *

+ * + * 

+ *   var CONFIG = require('config').customer;
+ *   ...
+ *   newCustomer.creditLimit = CONFIG.initialCredit;
+ *   database.open(CONFIG.db.name, CONFIG.db.port);
+ *   ...
+ *
+ * + * @module config + * @class Config + */ + +/** + *

+ * The configuration object is a shared singleton object within the application, + * attained by calling require('config'). + *

+ * 
+ * var CONFIG = require('config');
+ *
+ * + *

+ * Sometimes you only care about a specific sub-object within the CONFIG + * object. In that case you could do this at the top of your file: + *

+ * 
+ * var CONFIG = require('config').customer;
+ * or
+ * var CUSTOMER_CONFIG = require('config').customer;

+ * Set default configurations for a node.js module. + *

+ * + *

+ * This allows module developers to attach their configurations onto the + * default configuration object so they can be configured by the consumers + * of the module. + *

+ * + *

Using the function within your module:

+ * 
+ *   var CONFIG = require("config");
+ *   CONFIG.util.setModuleDefaults("MyModule", {
+ *     templateName: "t-50",
+ *     colorScheme: "green"
+ *   });
+ * 

+ *   // Template name may be overridden by application config files
+ *   console.log("Template: " + CONFIG.MyModule.templateName);
+ *

Make a configuration property hidden so it doesn't appear when enumerating + * elements of the object.

+ * + *

+ * The property still exists and can be read from and written to, but it won't + * show up in for ... in loops, Object.keys(), or JSON.stringify() type methods. + *

+ * + *

+ * If the property already exists, it will be made hidden. Otherwise it will + * be created as a hidden property with the specified value. + *

+ * + *

+ * This method was built for hiding configuration values, but it can be applied + * to any javascript object. + *

+ * + *

Example:

+ * 
+ *   var CONFIG = require('config');
+ *   ...
+ *
+ *   // Hide the Amazon S3 credentials
+ *   CONFIG.util.makeHidden(CONFIG.amazonS3, 'access_id');
+ *   CONFIG.util.makeHidden(CONFIG.amazonS3, 'secret_key');
+ *
+ * + * @method makeHidden + * @param object {object} - The object to make a hidden property into. + * @param property {string} - The name of the property to make hidden. + * @param value {*} - (optional) Set the property value to this (otherwise leave alone) + * @return object {object} - The original object is returned - for chaining. + */ +util.makeHidden = function(object, property, value) { + + // If the new value isn't specified, just mark the property as hidden + if (typeof value === 'undefined') { + Object.defineProperty(object, property, { + enumerable : false + }); + } + // Otherwise set the value and mark it as hidden + else { + Object.defineProperty(object, property, { + value : value, + enumerable : false + }); + } + + return object; +} + +/** + *

Make a javascript object property immutable (assuring it cannot be changed + * from the current value).

+ *

+ * If the specified property is an object, all attributes of that object are + * made immutable, including properties of contained objects, recursively. + * If a property name isn't supplied, all properties of the object are made + * immutable. + *

+ *

+ * + *

+ *

+ * New properties can be added to the object and those properties will not be + * immutable unless this method is called on those new properties. + *

+ *

+ * This operation cannot be undone. + *

+ * + *

Example:

+ * 
+ *   var config = require('config');
+ *   var myObject = {hello:'world'};
+ *   config.util.makeImmutable(myObject);
+ *
+ * + * @method makeImmutable + * @param object {object} - The object to specify immutable properties for + * @param [property] {string | [string]} - The name of the property (or array of names) to make immutable. + * If not provided, all owned properties of the object are made immutable. + * @param [value] {* | [*]} - Property value (or array of values) to set + * the property to before making immutable.

See the [error handling document](ERROR-HANDLING.md) for more details. + +```js +fetch('https://domain.invalid/') + .catch(err => console.error(err)); +``` + +#### Handling client and server errors +It is common to create a helper function to check that the response contains no client (4xx) or server (5xx) error responses: + +```js +function checkStatus(res) { + if (res.ok) { // res.status >= 200 && res.status < 300 + return res; + } else { + throw MyCustomError(res.statusText); + } +} + +fetch('https://httpbin.org/status/400') + .then(checkStatus) + .then(res => console.log('will not get here...')) +``` + +## Advanced Usage + +#### Streams +The "Node.js way" is to use streams when possible: + +```js +fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png') + .then(res => { + const dest = fs.createWriteStream('./octocat.png'); + res.body.pipe(dest); + }); +``` + +In Node.js 14 you can also use async iterators to read `body`; however, be careful to catch +errors -- the longer a response runs, the more likely it is to encounter an error. + +```js +const fetch = require('node-fetch'); +const response = await fetch('https://httpbin.org/stream/3'); +try { + for await (const chunk of response.body) { + console.dir(JSON.parse(chunk.toString())); + } +} catch (err) { + console.error(err.stack); +} +``` + +In Node.js 12 you can also use async iterators to read `body`; however, async iterators with streams +did not mature until Node.js 14, so you need to do some extra work to ensure you handle errors +directly from the stream and wait on it response to fully close. + +```js +const fetch = require('node-fetch'); +const read = async body => { + let error; + body.on('error', err => { + error = err; + }); + for await (const chunk of body) { + console.dir(JSON.parse(chunk.toString())); + } + return new Promise((resolve, reject) => { + body.on('close', () => { + error ? reject(error) : resolve(); + }); + }); +}; +try { + const response = await fetch('https://httpbin.org/stream/3'); + await read(response.body); +} catch (err) { + console.error(err.stack); +} +``` + +#### Buffer +If you prefer to cache binary data in full, use buffer(). (NOTE: `buffer()` is a `node-fetch`-only API) + +```js +const fileType = require('file-type'); + +fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png') + .then(res => res.buffer()) + .then(buffer => fileType(buffer)) + .then(type => { /* ... */ }); +``` + +#### Accessing Headers and other Meta data +```js +fetch('https://github.com/') + .then(res => { + console.log(res.ok); + console.log(res.status); + console.log(res.statusText); + console.log(res.headers.raw()); + console.log(res.headers.get('content-type')); + }); +``` + +#### Extract Set-Cookie Header + +Unlike browsers, you can access raw `Set-Cookie` headers manually using `Headers.raw()`. This is a `node-fetch` only API. + +```js +fetch(url).then(res => { + // returns an array of values, instead of a string of comma-separated values + console.log(res.headers.raw()['set-cookie']); +}); +``` + +#### Post data using a file stream + +```js +const { createReadStream } = require('fs'); + +const stream = createReadStream('input.txt'); + +fetch('https://httpbin.org/post', { method: 'POST', body: stream }) + .then(res => res.json()) + .then(json => console.log(json)); +``` + +#### Post with form-data (detect multipart) + +```js +const FormData = require('form-data'); + +const form = new FormData(); +form.append('a', 1); + +fetch('https://httpbin.org/post', { method: 'POST', body: form }) + .then(res => res.json()) + .then(json => console.log(json)); + +// OR, using custom headers +// NOTE: getHeaders() is non-standard API + +const form = new FormData(); +form.append('a', 1); + +const options = { + method: 'POST', + body: form, + headers: form.getHeaders() +} + +fetch('https://httpbin.org/post', options) + .then(res => res.json()) + .then(json => console.log(json)); +``` + +#### Request cancellation with AbortSignal + +> NOTE: You may cancel streamed requests only on Node >= v8.0.0 + +You may cancel requests with `AbortController`.

It's just + XML. +* A DOM Builder - You can use it to build an object model out of XML, + but it doesn't do that out of the box. +* XSLT - No DOM = no querying. +* 100% Compliant with (some other SAX implementation) - Most SAX + implementations are in Java and do a lot more than this does. +* An XML Validator - It does a little validation when in strict mode, but + not much. +* A Schema-Aware XSD Thing - Schemas are an exercise in fetishistic + masochism. +* A DTD-aware Thing - Fetching DTDs is a much bigger job. + +## Regarding `Hello, world!').close(); + +// stream usage +// takes the same options as the parser +var saxStream = require("sax").createStream(strict, options) +saxStream.on("error", function (e) { + // unhandled errors will throw, since this is a proper node + // event emitter. + console.error("error!", e) + // clear the error + this._parser.error = null + this._parser.resume() +}) +saxStream.on("opentag", function (node) { + // same object as above +}) +// pipe is supported, and it's readable/writable +// same chunks coming in also go out. +fs.createReadStream("file.xml") + .pipe(saxStream) + .pipe(fs.createWriteStream("file-copy.xml")) +``` + + +## Arguments + +Pass the following arguments to the parser function. All are optional. + +`strict` - Boolean. Whether or not to be a jerk. Default: `false`. + +`opt` - Object bag of settings regarding string formatting. All default to `false`. + +Settings supported: + +* `trim` - Boolean. Whether or not to trim text and comment nodes. +* `normalize` - Boolean. If true, then turn any whitespace into a single + space. +* `lowercase` - Boolean. If true, then lowercase tag names and attribute names + in loose mode, rather than uppercasing them. +* `xmlns` - Boolean. If true, then namespaces are supported. +* `position` - Boolean. If false, then don't track line/col/position. +* `strictEntities` - Boolean. If true, only parse [predefined XML + entities](http://www.w3.org/TR/REC-xml/#sec-predefined-ent) + (`&`, `'`, `>`, `<`, and `"`) + +## Methods + +`write` - Write bytes onto the stream. You don't have to do this all at +once. You can keep writing as much as you want. + +`close` - Close the stream. Once closed, no more data may be written until +it is done processing the buffer, which is signaled by the `end` event. + +`resume` - To gracefully handle errors, assign a listener to the `error` +event. Then, when the error is taken care of, you can call `resume` to +continue parsing. Otherwise, the parser will not continue while in an error +state. + +## Members + +At all times, the parser object will have the following members: + +`line`, `column`, `position` - Indications of the position in the XML +document where the parser currently is looking. + +`startTagPosition` - Indicates the position where the current tag starts. + +`closed` - Boolean indicating whether or not the parser can be written to. +If it's `true`, then wait for the `ready` event to write again. + +`strict` - Boolean indicating whether or not the parser is a jerk. + +`opt` - Any options passed into the constructor. + +`tag` - The current tag being dealt with. + +And a bunch of other stuff that you probably shouldn't touch. + +## Events + +All events emit with a single argument. To listen to an event, assign a +function to `on`. Functions get executed in the this-context of +the parser object. The list of supported events are also in the exported +`EVENTS` array. + +When using the stream interface, assign handlers using the EventEmitter +`on` function in the normal fashion. + +`error` - Indication that something bad happened. The error will be hanging +out on `parser.error`, and must be deleted before parsing can continue. By +listening to this event, you can keep an eye on that kind of stuff. Note: +this happens *much* more in strict mode. Argument: instance of `Error`. + +`text` - Text node. Argument: string of text. + +`doctype` - The ``. Argument: +object with `name` and `body` members. Attributes are not parsed, as +processing instructions have implementation dependent semantics. + +`sgmldeclaration` - Random SGML declarations. Stuff like `` +would trigger this kind of event. This is a weird thing to support, so it +might go away at some point. SAX isn't intended to be used to parse SGML, +after all. + +`opentagstart` - Emitted immediately when the tag name is available, +but before any attributes are encountered. Argument: object with a +`name` field and an empty `attributes` set. Note that this is the +same object that will later be emitted in the `opentag` event. + +`opentag` - An opening tag. Argument: object with `name` and `attributes`. +In non-strict mode, tag names are uppercased, unless the `lowercase` +option is set. If the `xmlns` option is set, then it will contain +namespace binding information on the `ns` member, and will have a +`local`, `prefix`, and `uri` member. + +`closetag` - A closing tag. In loose mode, tags are auto-closed if their +parent closes. In strict mode, well-formedness is enforced. Note that +self-closing tags will have `closeTag` emitted immediately after `openTag`. +Argument: tag name. + +`attribute` - An attribute node. Argument: object with `name` and `value`. +In non-strict mode, attribute names are uppercased, unless the `lowercase` +option is set. If the `xmlns` option is set, it will also contains namespace +information. + +`comment` - A comment node. Argument: the string of the comment. + +`opencdata` - The opening tag of a ``) of a `` tags trigger a `"script"` +event, and their contents are not checked for special xml characters. +If you pass `noscript: true`, then this behavior is suppressed. + +## Reporting Problems + +It's best to write a failing test if you find an issue. I will always +accept pull requests with failing tests if they demonstrate intended +behavior, but it is very hard to figure out what issue you're describing +without a test. Writing a test is also the best way for you yourself +to figure out if you really understand the issue you think you have with +sax-js. diff --git a/node_modules/sax/lib/sax.js b/node_modules/sax/lib/sax.js new file mode 100644 index 0000000..795d607 --- /dev/null +++ b/node_modules/sax/lib/sax.js @@ -0,0 +1,1565 @@ +;(function (sax) { // wrapper for non-node envs + sax.parser = function (strict, opt) { return new SAXParser(strict, opt) } + sax.SAXParser = SAXParser + sax.SAXStream = SAXStream + sax.createStream = createStream + + // When we pass the MAX_BUFFER_LENGTH position, start checking for buffer overruns. + // When we check, schedule the next check for MAX_BUFFER_LENGTH - (max(buffer lengths)), + // since that's the earliest that a buffer overrun could occur.
