1
REST is the most common communication standard between computers over the internet.
2
What is it?
3
Why is it so popular?
4
Let's take a look.
5
API stands for Application Programming Interface.
6
It is a way for two computers to talk to each other.
7
The common API standard used by most mobile and web applications to talk to the servers is called REST.
8
It stands for Representational State Transfer.
9
It is a mouthful.
10
What does that mean?
11
REST is not a specification.
12
It is a loose set of rules that has been the common standard for building web APIs since the early 2000s.
13
An API that follows the REST standard is called a RESTful API.
14
Some real-life examples are Twilio, Stripe, and Google Maps.
15
Let's look at the basics of REST.
16
A RESTful API organizes resources into a set of unique URIs or Uniform Resource Identifiers.
17
The URIs differentiate different types of resources on a server.
18
Here are some examples.
19
The resources should be grouped by noun and not verb.
20
An API to get all products should be slash products and not slash get all products.
21
A client interacts with a resource by making a request to the endpoint for the resource over HTTP.
22
The request has a very specific format as shown here.
23
The line contains a URI for the resource we'd like to access.
24
The URI is preceded by an XGTP verb, which tells the server what we want to do with the resource.
25
A POST request means we want to create a new resource.
26
A GET means we want to read the data about an existing resource.
27
A PUT is for updating an existing resource.
28
A DELETE is for removing an existing resource.
29
You might have heard the acronym CRUD.
30
This is what it stands for.
31
In the body of these requests, there could be an optional HTTP request body that contains a custom payload of data, usually encoded in JSON.
32
The server receives the request, processes it, and formats a result into a response.
33
The first line of the response contains the HTTP status code to tell the client what happened to the request.
34
A well implemented RESTful API returns proper HTTP status codes.
35
The 200 level codes mean the request was successful.
36
The 400 level codes mean something was wrong with our request.
37
For example, the request contained incorrect syntax.
38
At the 500 level, it means something ran wrong at the server level.
39
For example, the service was unavailable.
40
A well-behaved client could choose to retry a fail request with a 500 level status quo.
41
We said could choose to retry because some actions are not idempotent and those require extra care when retrying.
42
When an API is idempotent, making multiple identical requests has the same effect as making a single request.
43
This is usually not the case for a post request to create a new resource.
44
The response body is optional and could contain the data payload and is usually formatted in JSON.
45
There's a critical attribute of REST that is worth discussing more.
46
A REST implementation should be stateless.
47
It means the two parties don't need to store any information about each other, and every request and response is independent from all others.
48
This leads to web applications that are easy to scale and well-behaved.
49
There are two final points to discuss to round out a well-behaved RESTful API.
50
If an API endpoint returns a huge amount of data, use pagination.
51
A common pagination scheme uses limit and offset as parameters.
52
Here is an example.
53
If they are not specified, the server should assume sensible default values.
54
Lastly, versioning of an API is very important.
55
allows an implementation to provide backward compatibility so that if we introduce breaking changes from one version to another,
56
consumers can get enough time to move to the next version.
57
There are many ways to version an API.
58
The most straightforward is to prefix the version before the resource on the URI.
59
For instance, like this.
60
Restful API is simple and effective when applied sensibly.
61
It may not be the best choice for all companies, but it is simple and good enough, and that's why it is so widely used.
62
There are other popular API options like GraphQL and GRPC.
63
We'll discuss those and compare them in separate videos.

इस पाठ की शब्दावली और बोलने के सुझाव

इस वीडियो में शैडोइंग के लिए 65 वाक्य और 753 शब्द हैं। बोला गया हिस्सा 5:11 लंबा है। वक्ता लगभग 145 शब्द प्रति मिनट की स्थिर गति से बोलता है, जो शैडोइंग के लिए आरामदायक है। केवल 78% शब्द अंग्रेज़ी के 3,000 सबसे आम शब्दों में से हैं, इसलिए शब्दावली कठिन है।

इस वीडियो की मुख्य शब्दावली

वीडियो के 15 सीखने लायक शब्द, उच्चारण और अर्थ के साथ:

शब्दउच्चारणअर्थ
resource संज्ञा/ɹɪˈzɔːs/संसाधन
server संज्ञा/ˈsɝvɚ/सर्वर
behave क्रिया/bɪˈheɪv/आचरण करना, बर्ताव करना
implementation संज्ञा/ˌɪmplɪmənˈteɪʃən/कार्यान्वयन
optional विशेषण/ˈɑp.ʃə.nəl/वैकल्पिक
verb संज्ञा/vɝb/क्रिया, क्रियापद
compare क्रिया/kəmˈpɛɚ/तौलना
custom संज्ञा/ˈkʌstəm/प्रथा, रीति
introduce क्रिया/ˌɪntɹəˈdus/परिचय
default संज्ञा/dɪˈfɔlt/व्यतिक्रम
organize क्रिया/ˈɔɹɡənaɪz/व्यवस्था करना
incorrect विशेषण/ˌɪn.kəˈɹɛkt/त्रुटिपूर्ण
attribute संज्ञा/ˈæt.ɹɪˌbjut/गुण, सिफ़त
unavailable विशेषण/ˌʌnəˈveɪləbəl/अनुपलब्ध
noun संज्ञा/naʊn/संज्ञा, नाम

ध्यान देने योग्य उच्चारण

वक्ता 4 बार संक्षिप्त रूपों का प्रयोग करता है, जैसे we'll, don't, we'd। इन्हें वैसे ही छोटा बोलें जैसा आप सुनते हैं।

  • “sh” और “zh” की ध्वनियाँ: implementation /ˌɪmplɪmənˈteɪʃən/, optional /ˈɑp.ʃə.nəl/, differentiate /dɪf.əˈɹɛn.ʃi.eɪt/, pagination /ˌpæd͡ʒəˈneɪʃən/
  • लंबे शब्द — बलाघात सही रखें: implementation /ˌɪmplɪmənˈteɪʃən/, unavailable /ˌʌnəˈveɪləbəl/, differentiate /dɪf.əˈɹɛn.ʃi.eɪt/, compatibility /kəmˌpætəˈbɪlɪti/, parameter /pəˈɹæm.ə.tɚ/

इस वीडियो से अभ्यास कैसे करें

  1. पहले बिना बोले पूरा वीडियो एक बार सुनें और जो शब्द नहीं आते उन्हें लिख लें।
  2. सामान्य गति पर एक-एक वाक्य की शैडोइंग करें और हर वाक्य तब तक दोहराएँ जब तक आपकी लय वक्ता से न मिल जाए।
  3. अपनी आवाज़ रिकॉर्ड करें और मूल से तुलना करें, ख़ासकर resource, server, behave जैसे शब्दों पर ध्यान दें।

शैडोइंग तकनीक क्या है?

शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
